Crushed rock products shall be supplied only from a VicRoads accredited source.

Source rock types from which crushed rock base and subbase can be produced are specified in Section 11 - Source Rock for the Production of Crushed Rock and Aggregates.

Construction requirements for unbound flexible pavements incorporating crushed rock are covered in Section 13 - Unbound Flexible Pavement Construction.

12.2 DEFINITIONS

Additive

A material that may be added to crushed rock to improve its workability and physical properties.

Aggregates

For the purposes of this specification, fine aggregate shall be the portion of the crushed rock mixture passing the 4.75 mm sieve and coarse aggregates shall be the portion of the crushed rock mixture retained on the 4.75 mm sieve.


The assigned Los Angeles Value is a hardness rating derived from Los Angeles Value test results, which is assigned to each source by VicRoads on an annual basis as a part of the accreditation process. The value is assigned on the basis of test data obtained from testing products.

Crushed Rock

Crushed rock is composed of rock fragments produced by the crushing, scalping and screening of igneous, metamorphic or sedimentary source rock which conforms to the requirements of Section 801, with or without additives, produced in a controlled manner to close tolerances for grading and plasticity.

For the purpose of this specification crushed rock is to be supplied in various classes broadly defined as follows:

Class 1 is a premium cohesive pavement base material for unbound pavements where a very high standard of surface preparation for a sprayed sealed or thin asphalt surfacing is required. It has a minimum Plasticity Index requirement and may have additional requirement for maximum permeability when used for heavy duty unbound pavements.



Class 2 is a high quality pavement base material for unbound flexible pavements in locations where a very high standard of surface preparation may not be required. Class 2 crushed rock does not have a minimum Plasticity Index or a maximum permeability requirement.

Class 3 is a high quality upper subbase material for heavy duty unbound flexible pavements. It may have a minimum permeability requirement to provide positive drainage to the sub-surface drains. Where specified, Class 3 may be used as base for lightly trafficked pavements provided the material produces sufficient cohesive fines during compaction.

12.3 SOURCE ROCK

Source rock shall comply with the requirements of Section 11.

Material from a quarry or non-quarry site shall not be used until approval from the Superintendant has been given in writing.

14.9 CONSTRUCTION

14.9.1 General

Construction includes the pulverisation of any seal or asphalt surfacing, premixing of in situ materials, supply and spreading of any additional granular material, supply, spreading and mixing of cementitious binder into the in situ pavement material, and compaction, trimming and curing of the stabilised layer.

Unless otherwise specified, stabilisation work undertaken each day shall be completed across the full pavement width.

Stabilisation operations may continue during light rainfall if the moisture content of the in situ pavement material can be maintained below modified optimum moisture content.

Only sufficient area of pavement is to be pulverised that can be mixed and fully compacted in one day. For stabilised patching work which is to be trafficked or sealed immediately after completion of compaction, only sufficient pavement area shall be opened up to enable work to be completed within the maximum allowable working time specified in Table 14.1

14.9.2 Preparation of subgrade

The subgrade shall be mixed in a way ensure that as much of structural integrity of the layer is maintained.



The contractor may opt to spread the binder on the trimmed subgrade surface prior to mixing.

14.9.3 Spreading of Lime or Cementitious Binder

Spreading shall not be carried out at times when lime or cementitious binder could become air borne or dispersed in such a way as to become a nuisance or a hazard to persons, property or livestock.

Immediately following completion of spreading, the Contractor shall check and record the Average Spreading Rates and the Uniformity of Spread.. If the required Spreading Rate for lime or cementitious binder exceeds 15 kg/m2, it shall be spread in two equal spreading runs with material from the first spread run being fully mixed into the pavement material prior to the second spreading run being undertaken.

The prepared pavement shall not be trafficked until the cementitious binder has been mixed into the pavement material.

14.9.4 Mixing in Cementitious Binder

Mixing shall commence as soon as practical after spreading of the cementitious binder and shall continue until all pavement materials and cementitious binder are uniformly blended throughout the full depth of the stabilised layer.

The moisture content of the pavement material prior to addition of the cementitious binder shall be within the range 85% to 100% of the Modified optimum moisture content. Additional water shall be added to hydrate the cementitious binder.

14.9.5 Compaction

Compaction of the stabilised layer shall commence immediately after mixing. Compaction equipment shall work as close as practicable behind the mixer to maximise the time available for compaction. Compaction and trimming shall be carried out in a continuous operation.

All compaction shall be completed within the times specified in Table 14.1 after addition of the cementitious binder.

Where necessary during compaction, the Contractor shall water the material to maintain the moisture content within 85% to 100% Modified optimum moisture content.

14.9.6 Trimming

On completion of initial rolling, the stabilised material shall be trimmed to the specified surface tolerances. Light applications of water may be applied during this operation to replace evaporated moisture and to assist in rapid achievement of a tightly knit surface.

All surface irregularities shall be rectified by the Contractor within the maximum working time for the cementitious binder used as specified in Table 14.1. Rectification beyond the maximum working time for the cementitious binder shall be carried out by replacing material with freshly stabilised material as necessary.

The material trimmed off shall be either cut to waste and if necessary, removed from site or, alternatively it may be transported to another location to be incorporated into a stabilised layer.



14.10 JOINTING

Longitudinal joints shall be avoided by completing a full carriageway width each day. If a longitudinal joint is required, because of rain or traffic control requirements, it shall be located at a lane line or in the centre of the carriageway. Transverse joints shall be formed where stabilisation operations have been halted for more than the time specified in Table 307.052 and at the end of each day's work.

Joints shall be formed by cutting back into the fully compacted previously stabilised material by a minimum of 300 mm which shall be remixed into the new work. Additional stabilising agent shall be added to the area of previously stabilised material to be remixed. Placement of additional cementitious binder shall be deemed to be part of the joint construction.

14.11 TEST ROLLING

Stabilised layers shall pass test rolling in accordance with Section 8, prior to acceptance of the layer.

Any unstable areas detected by test rolling shall be rectified.

14.12 MAINTENANCE OF THE STABILISED SURFACE PRIOR TO SURFACING OR OVERLAY

The Contractor shall keep the stabilised pavement surface moist and protected from damage by traffic or construction activities until either a further pavement layer or the bituminous surfacing is applied.

14.13 PRELIMINARY TRIAL

If directed by the Superintendent, the Contractor shall carry out a preliminary trial of the proposed stabilising operation.

The trial shall determine:

the effectiveness of the construction plant; the number of passes of the stabilisation machine necessary to achieve uniform

pulverisation and mixing; the field moisture content required to achieve specified compaction requirements; the rolling routine required to meet specified compaction requirements.

The trial section shall be located within the Works area.

The length of the trial section shall be between 100 and 200 metres over the full width of the area proposed for stabilisation.

***Stabilisation work shall not proceed outside the trial section (one lot) until the Superintendent has reviewed all aspects of the stabilising operation. The Superintendent's review of the stabilising plant and procedures will be provided to the Contractor by the end of the next working week day after the trial's completion. If the Specification requirements are not met for this trial section, the Superintendent may direct that another trial section be stabilised or the rejected section be re-stabilised and presented for re-assessment.



14.14 Pavement Construction

The surface of each compacted layer shall be kept moist for a period of seven days unless covered at an earlier stage with the succeeding layer or with an approved curing membrane.

Construction or other traffic shall not use a compacted layer within 24 hours of placement without the approval of the Superintendent.

The subbase shall be kept in good order and condition and free from contamination.

*** The Contractor’s Environmental Management Plan shall include procedures to minimise all risks of damage to the environment associated with priming and primersealing.

allow the cementitious treated subbase to cure for seven days without trafficking (except for the application of a prime or primerseal);

prevent construction plant from using the pavement during the seven day curing period apart from that required to maintain and cure the surface; and

after the seven days curing period, restrict construction traffic to vehicles with a maximum axle group load of 4 tonnes until asphalt base and intermediate courses are placed (priming, primersealing and asphalt placement activities excepted).

14.15 TEST ROLLING

Test rolling may be carried out in accordance with the requirements of Section 8 on the cementitious treated subgrade and subbase layers within the maximum allowable working time for the relevant binder and time of year as specified.

14.16 CURING AND PROTECTION OF COMPACTED LAYERS

Unless there are special design and construction conditions specified for placing of multiple layers, cementitious treated subbase with a pavement design modulus exceeding 500 MPa shall be placed in a single layer. The minimum compacted thickness shall be not less than 100 mm and the maximum compacted thickness shall be no more than 180 mm and constructed within the tolerances specified.

14.17 REQUIREMENTS FOR TESTING AND ACCEPTANCE OF COMPACTION AND STRENGTH

14.17.1 General

Lot Testing Requirements

The maximum lot size shall be the area of work completed on the same day up to 4,000 m2 provided that the whole of the lot is essentially a uniform material similar to material used for the relevant mix design applicable to the lot. If the maximum binder working time requires the area or work to be completed in one day to split into sub-sections, each sub-section shall be treated as a separate lot.

If the material is too variable to be able to assign a single maximum dry density for the lot, a separate reference density shall be determined for each test site.

The calculation of density ratio shall be based on Modified compactive effort of the laboratory prepared sample containing the design rate of cementitious binder.

Determination of the Density Ratio

If it is not possible to transport extracted samples of mixed material to an established laboratory for determination of the reference density within the



maximum working time of the cementitious binder, and the Superintendent agrees that establishment of a site laboratory for this purpose is not warranted, the following procedure shall be used to determine the Density Ratio:

1. measure field density on completion of compaction;

2. extract samples and transport to an offsite laboratory;

3. determine the reference density for the laboratory compacted samples as soon as practicable but not exceeding 24 hours;

4. determine the Density Ratio (DR) from -

DR = DRt x DDCF

Where: DRt = Density Ratio calculated using the reference density determined at time (t)

DDCF = Density Decay Correction Factor determined from Table 14.2 corresponding to time (t), the binder type and the time of year construction is being undertaken.

Any unstable areas within limits of work and depth of stabilisation detected by test rolling shall be rectified by the Contractor and re-presented for test rolling.

14.17.3 Assessment of Compaction for Thick Layers

For compacted layers in excess of 200 mm thick, the Contractor shall measure the field density of the layer in two sub-layers of equal thickness in accordance with the relevant Test Method. At each test site the sub-layer with the lower of the two density test results shall be used in the calculation of the Characteristic or Mean Density Ratio for assessment of compaction in accordance with Clause 307.13.

14.18 REQUIREMENTS FOR TESTING AND ACCEPTANCE OF SPREADING RATES

14.18.1 Mat or Tray System

The average spreading rate of lime or cementitious binder shall be ascertained by dividing the mass of cementitious binder spreading by the area over which the cementitious binder has been spread. Where the average spreading rate is less than the specified or design spread rate, additional cementitious binder shall be spread to bring the average rate up to at least the design spread rate.

The Contractor shall check the uniformity of spreading rate of lime or cementitious binder at the frequency specified in Clause 307.15 by placing a minimum of three mats or trays with a plan area not less than 1 m2 in the path of the spreading vehicle at an equal spacing of not less than 25% of the length of the spreading run. The spreading rate over each mat or tray shall be calculated by dividing the mass of lime or cementitious binder deposited on each mat or tray by the plan area of the mat or tray. Where the spread rate so determined for any mat or tray is less than the specified rate by more than 10%, additional cementitious binder shall be spread over the part or all of the area over which the lime or cementitious binder has been spread.

14.18.2 Continuous Weighing System

The mass of lime or cementitious binder spread over the pavement surface may be measured and recorded by a spreader fitted with a fully calibrated electronic weigh scale system capable of continuously measuring and recording the mass of lime or cementitious binder at intervals of not more than 100 m of forward travel. The Contractor shall have a current certificate of calibration for the computerised spreading equipment and shall produce evidence of the actual running spread rate when requested by the Superintendent.

14.19 MINIMUM TESTING FREQUENCY

The Contractor shall test the materials and the stabilised pavement layer at a frequency which is sufficient to ensure that the materials and work under the Contract comply with the specified requirements but not less than the frequency specified in Table 14.3

constructed to meet specified shape and level requirements; homogenous and consistent with the material in the pavement base layer; uniform in texture; free of tearing and scabbing; free of lamination on top of or within 75 mm of the finished surface; level with adjacent sealed areas and edgings at the joints; a hard dense and tight surface capable of being swept with a rotary road broom or

similar; free of loose and foreign materials; dried back to the moisture content as specified in Clause 16.3

Any imperfections as listed above shall be corrected in a manner approved by the Superintendent.

In preparing the pavement surface the Contractor shall avoid construction practices that produce a slurry of fine material. The addition of fine material to the surface is not permitted.

The total area of the work shall be presented to the Superintendent for acceptance for surfacing as one lot.

15.3 DRYING BACK OF PAVEMENT BASE PRIOR TO BITUMINOUS SURFACING

The uppermost pavement layer after preparation of the surface and prior to priming or primersealing shall be dried back in moisture content to an extent that the mean Moisture Ratio as determined from six randomly selected sites is less than 60% of the optimum moisture content based on Modified compactive effort, with an individual result not exceeding 70%.

The mean Moisture Ratio shall be determined in accordance with VicRoads Test Method - Moisture Ratio determination for assessment of dry-back of granular pavement materials, using nuclear gauge.

The maximum lot size to be presented for testing under this provision shall be 4000 m², and testing shall be undertaken no more than 24 hours before priming or primersealing. Should the mean Moisture Ratio be more than 60% and less than 65% and providing that no individual result is more than 70%, the lot may be accepted by the Superintendent subject to Ball Penetration testing in accordance with Austroads test method AG:PT/T251 being undertaken at six randomly selected sites. No individual result from such Ball Penetration testing shall be more than 3 mm.

1. Procedure Statement The health, wellbeing and safety of personnel are of paramount importance to Swan Hill Rural City Council. All individuals have a right to be safe at all Swan Hill Rural City Councils workplaces. Alcohol and Other Drugs (AOD), when present in the workplace, have the potential to increase risk of harm in the workplace and adversely impact upon fitness for work. The issue of adverse affects of the consumption of AOD is covered under Part 99 of the Civil Aviation Safety Regulations 1998 (CASRs) and the Occupational Health and Safety Act 2004

(OHS Act 2004). The Act requires:

• employers to provide and maintain a working environment that is safe and without risks to health (Section 21). Without in any way limiting the generality of this duty, employers have duties with respect to plant, substances and systems of work; providing information, instruction, training and supervision to their employees as well as monitoring their health and safety. (Sections 21(2) and 22);

• employers and self-employed persons to ensure that persons other than employees (including the public) are not exposed to risks to their health and safety arising from the undertaking of the employer or self-employed person. (Sections 23 and 24); and

• employees to take reasonable care for their own health and safety and that of others (by ensuring they are not affected in a way that may put themselves or others at risk by use of AOD); and to cooperate with employers in their efforts to comply with OHS requirements. (Section 25).

Swan Hill Rural City Council takes a multi-strategy approach that incorporates education, support, testing and performance management. The policy is based on safety outcomes and not whether a positive test result is illicit or legal. This policy also recognises permissible therapeutic drug use under the guidance of a physician or pharmacist. Swan Hill Rural City Council’s Drug and Alcohol Management Plan for Safety Sensitive Aviation Activity Employees PRO/STAFF125; outlines the strategies and processes that Swan Hill Rural City Council will use to manage the risks associated with the use of Alcohol and other Drugs by persons at all Swan Hill Rural City Council workplaces.

considered fit to resume performing SSAA activities, the employee receives a confirmatory drug test and records, for the test, a result that: 4.1. Was not a positive result; and 4.2. A DAMP medical review officer is satisfied the test indicates the absence of

testable drug use. Swan Hill Rural City Council will permit a SSAA employee time to attend a nominated drug or alcohol intervention program, if: 1. A DAMP medical review officer has advised Swan Hill Rural City Council that the

employee should attend the program; and 2. The employee is returning to work after a period during which the employee was not

permitted to perform or be available to perform an SSAA because of a positive test result for testable drug use or alcohol use.

8. Self-Referral An aim of this policy and the available educational material is to encourage Swan Hill Rural City Council personnel to recognise problematic use of substances and to obtain the assistance they need. Any employee who seeks assistance from their Manager or from Swan Hill Rural City Council will be encouraged to seek professional assistance. The matter will be treated in the strictest confidence. Personnel seeking assistance from Swan Hill Rural City Council management will be offered assistance, by way of counselling or other treatment / rehabilitation program. They may be provided with flexible leave arrangements in order to complete any treatment / rehabilitation program.




Rural City Council




Swan Hill Rural City Council will use existing counselling services to provide therapeutic interventions to Swan Hill Rural City Council employees who require professional assistance to manage problematic AOD use. In determining the appropriate provider, Swan Hill Rural City Council considered matters of accreditation and qualification of the agency/practitioners, organisational procedures and protocols, and sought assurances of client confidentiality and security of information. 9. Role of the Medical Review Officer Swan Hill Rural City Council will consult a DAMP medical review officer as part of its responsibilities under this program and CASR 99. What is the role of a Medical Review Officer? Swan Hill Rural City Council will consult a DAMP medical review officer in the following circumstances: 1. If a drug test conducted under the program returns a confirmatory drug test result for a

Swan Hill Rural City Council SSAA employee that is a positive result — to determine if the presence and level of a testable drug detected by the test could be the result of legitimate therapeutic treatment or some other innocuous source; and

2. To review medical information concerning a person’s failure to give a body sample for drug or alcohol testing because of a claimed medical condition;

3. To determine, in consultation with the employee’s treating clinician (if any) if the employee is fit to resume performing, or being available to perform, a SSAA after being required to cease performing or being available to perform SSAA for a drug or alcohol testing related incident.

10. Disciplinary Action Disciplinary action for employees will be taken as per Swan Hill Rural City Councils Disciplinary procedures in the Human Resources Manual. Disciplinary action for Contractors will be as described in Councils contractor agreement. 11. Procedural Reviews This procedure will be reviewed every two years by the OHS Coordinator and Swan Hill Rural City Councils Occupational Health & Safety Committee. 12.

The Contractor will comply with any and all directions by Council relating to OH&S.

1.1 Legislative Compliance

The Contractor must comply with and ensure that its employees, subcontractors and agents comply with all applicable Acts, regulations, local laws and by-laws, Codes of Practice, Australian Standards and Council’s OH&S policies and procedures that are in any way applicable to this Contract Agreement or the performance of the works under this Contract Agreement.

If the Contractor is required by the Occupational Health and Safety (Incident Notification) Regulations



1997 or by any other regulations to give any notice of an accident occurring whilst performing works under this Contract Agreement, the Contractor must at the same time, or as soon thereafter as possible under the circumstances, give a copy of the notice to Council.

Council may direct the Contractor to suspend the performance of works until such time as the Contractor satisfies Council that the works will be resumed in conformity with applicable health and safety provisions.

During any period of suspension referred to above, Council shall not be required to make any payments whatsoever to the Contractor.

If the Contractor fails to rectify any breach of health and safety for which the performance of works has been suspended, or if the Contractor’s performance has involved recurring breaches of health and safety, the Council may, at its absolute discretion, terminate the Contract Agreement, without further obligation to the Contractor. In this event, Council’s liability shall be limited to payment for the works performed and costs incurred by the Contractor up to the time of termination or an earlier suspension of works.
