1. Introduction

1.1 Scope

This Standard specifies the procedures to be followed for the approval and delivery of Pavement Asset Repair and Renewal (PARR) Schemes on the National Road network and shall be read in conjunction with AM-PAV-06050 which sets out the technical requirements for such schemes.

1.2 Implementation

The procedures described in this Standard shall be followed for all PARR Schemes on National Roads. The Standard shall be applied to schemes already being prepared unless, in the opinion of Transport Infrastructure Ireland (TII), application would result in significant additional expense or delay progress. In such cases TII shall issue appropriate directions to the Implementation Authority (IA).

1.3 Definitions

The following definitions will apply to this Standard:

a) Approval Gateway: An Approval Gateway is a systematic review of proposals which require formal TII approval prior to proceeding to the next stage of the process.

b) As-Built Record: Record of construction which can include, but is not limited to, drawings, documents, photographs, surveys, maps, models or any other record, providing a final statement of what works were completed on a road construction scheme. The as-built records will comply with the requirements of CC-CMG-04001.

c) Design Organisation: Usually an Implementation Authority, National Roads Design Office (or a Consultant acting on their behalf) who are responsible for the design of the Scheme.

d) Designer: The Designer will be a Chartered Engineer or equivalent and who has at least 5 years’ experience in the design and supervision of PARR Schemes. This experience should include a thorough understanding of the interaction between the attributes of drainage, geotechnics, utility issues, land issues and pavement design.

e) Employer’s Representative: As defined in the Public Works Contract.

f) Emergency Pavement Repair Scheme: PARR schemes which have to be carried out quickly in response to emergencies to ensure the safety and continued serviceability of the road. For example, these repairs may follow collisions, diesel spillage or unexpected and rapid deterioration of the pavement.

g) Implementation Authority: The Implementation Authority is the relevant road authority responsible for the PARR scheme.

h) Life Cycle Cost Analysis: Life-cycle cost analysis is the process of calculating whether a particular investment, resulting from a specific design strategy, will generate a positive return on investment over the life of the renewed pavement.

i) Minor Pavement Repair Scheme: Pavement schemes and repairs not exceeding €200,000 (excluding Vat) in estimated cost.


Page 2

j) National Road Network: The primary and secondary road network in Ireland which comprises motorways, dual carriageways and single carriageway roads.

k) Original Cross-Sectional Profile: The cross-sectional profile of the road as originally constructed and prior to any deterioration including settlement during the subsequent use of the road pavement. If drawings and other records are not available then engineering judgement may need to be applied to establish the original profile.

l) Pavement Asset Management System (PAMS): The network pavement asset management system which is maintained and managed by TII NM.

m) Pavement Asset Repair and Renewal (PARR) Scheme: Activity targeted at extending the life of an existing road pavement and/or improving its load carrying capacity or skid resistance. Examples include overlay and inlay works and edge strengthening of an existing road pavement.

n) TII: Transport Infrastructure Ireland.

o) TII Network Management (TII NM): Division within TII responsible for the management and operation of the road network including responsibility for pavement management and the operation of the TII Pavement Asset Management System (PAMS).

p) TII Regional Management (TII RM): Division within TII responsible for the delivery of the roads programme for the Network within specific geographic regions.

1.4 Background

Road pavements represent both a considerable investment in assets and a significant maintenance liability as it is this element of the road which is most exposed to deterioration due to the effects of traffic loading, weather, drainage and movements of the supporting structures and earthworks. To mitigate this deterioration requires management and ongoing investment in pavement repairs and renewals to retain and enhance the value of the road asset and to maintain a safe driving surface for road users.

The overall strategic objective of the PARR procedures is to maintain the overall asset value for the minimum life cycle costs by ensuring optimal management of the National Road Network Pavements. Optimal management of the pavement assets requires the combination of local knowledge, intervention and network-wide monitoring, knowledge sharing and co-ordination, especially as new technologies present opportunities to reduce both the economic and environmental costs.

The delivery of the PARR Scheme will be the responsibility of the IA.

TII NM maintains a PAMS which comprises a large database of information relating to the entire National Road network. The system hosts the results of annual pavement condition surveys together with site-specific survey data and as-built records. This data is analysed to determine PARR priorities at a national level, so as to optimise the efficiency of investment in the road network.

The effectiveness of this system depends on the quality of the information available. This Standard prescribes procedures for the reporting of as-built information by the IA. When works are carried out and not reported into the system, the analytical capabilities of PAMS are compromised.

1.5 Submissions

All submissions, reports, tables and associated documents for all PARR Schemes shall be submitted in accordance with this Standard.


Page 3

1.6 Mutual Recognition

The construction and maintenance of road pavements will normally be carried out under contracts incorporating the TII Specification for Road Works. In such cases works, goods or materials conforming to harmonised European Standards (hEN) where applicable will be acceptable in accordance with the terms of the Clauses 104 and 105 of the TII Specification for Road Works (CC-SPW-00100). Contracts that do not contain these clauses must contain suitable clauses of mutual recognition having the same effect. Advice should be sought in relation to such situations from the TII Director of Network Management.

Construction products must be supplied with appropriate CE marking in accordance with the Construction Products Regulation (CPR) or as required by the TII Specification for Road Works.

In order to allow a manufacturer to draw up a declaration of performance for a construction product which is not covered or not fully covered by a harmonised standard, it is necessary to provide for a European Technical Assessment for these products. For more information on the implementation of the Construction Products Regulation in Ireland visit the Building Standards Section of the Department of Housing, Planning and Local Government website:

http://www.housing.gov.ie/housing/building-standards/construction-products-regulation/construction-products-regulation-cpr

1.7 Departures from Design Standards

In exceptional situations, TII may be prepared to agree to a Departure from Standards. Implementation Authorities or Design Organisations wishing to consider pursuing this course shall discuss any such option at an early stage in design with TII NM. Proposals to adopt Departures from Standard must be submitted by the IA or Design Organisation to TII and formal approval received BEFORE incorporation into a design layout. Approval cannot and will not be given retrospectively for Departures identified at a later stage. Refer to GE-GEN-01005 Departures from Standards and Specifications for further information.

2. Pavement Asset Repair and Renewal Scheme Approval Process

2.1 Approval Process

The process of identifying, developing and delivering PARR schemes is illustrated in Figure 2.1.

Pavement repair and renewal schemes typically progress through the following six phases:

a) Selection of PARR schemes.

b) Data collection.

c) Pavement asset repair and renewal proposal.

d) Procurement.

e) Monitoring of pavement repair and renewal works.

f) Close out of PARR scheme.

The key elements of each of the above phases for a PARR scheme are described in the subsequent Chapters 3 to 8. Chapter 9 deals with PARR schemes when classified as emergency pavement repair or minor pavement repair schemes.

2.2 Approval Gateways

All PARR schemes must be processed through the Approval Gateways shown in Figure 2.1.

On Figure 2.1 the Approval Gateways are shown in boxes with bold margins and uppercase text.


Page 5 Figure 2.1 Pavement Repair and Renewal Flow Chart

TII notifies the relevant IA of sections of the national road network for priority development into pavement asset repair and renewal schemes either through the annual allocations process or through direct contact (recorded in minutes or by e-mail) with the TII NM Senior Engineer and RM Senior Engineering Inspector.

IA carries out all necessary studies and surveys and reviews all relevant information to determine the likely

causes of the pavement deterioration for the sections notified and proposes appropriate repair and renewal

solutions – taking account of the principles contained within TII Publication AM-PAV-06050. These proposals

will be summarised in the PARR Proposal which shall be submitted to TII NM for approval.

2.3 PARR Schemes

The purpose of PARR Schemes is to extend the life of an existing road pavement and/or improve its load carrying capacity or skid resistance. Examples include overlay and inlay works and edge strengthening of an existing road pavement.

In some cases a PARR scheme may involve non-substantive geometric change(s), which may be progressed as a PARR scheme as defined in this Standard (AM-PAV-06049), subject to agreement with TII NM prior to approval of the PARR proposal under Gateway No. 1.

Examples of non-substantive geometric changes that may be considered as part of a PARR scheme include:

a) Road widening work, not requiring landtake.

b) Modifications to the horizontal road centreline.

c) Modifications to the vertical alignment.

d) Overlay and inlay works that do not negatively affect stopping or overtaking sight distance.

e) Overlay and inlay works which regulate the camber of the existing road, including removal of adverse camber.

f) Changes to the original cross-sectional profiles.

g) Junction improvements within existing road boundary.

h) Curve widening within existing road boundary.

In these situations, the design of the non-substantive geometric change(s) shall comply with the relevant TII design standards.

2.4 PARR Schemes in Relation to Road Safety Improvement Schemes

Where a Road Safety Improvement Scheme overlaps with a PARR scheme, the implementation of the Road Safety Improvement Scheme may be combined with the PARR scheme subject to the prior approval of TII NM and the safety measures and pavement works may then be combined in one design.

The combined scheme should comply with the requirements of this Standard (AM-PAV-06049) and the relevant TII road safety scheme procedures, including the provision to TII RM of the Updated PAMS Database Information Sheet as outlined in Appendix E of this Standard.

2.5 Exceptions to the Pavement Repair and Renewal Process

Exceptions to the standard process will apply to PARR schemes classified as emergency pavement repair schemes or as minor pavement repair schemes. These exceptions are described below.

2.6 Emergency Pavement Repair Schemes

The IA must obtain approval from TII NM to consider the PARR scheme as an emergency pavement repair. If an emergency repair is required, the IA will keep TII RM informed on the progress of the Works.


Page 7

Emergency pavement repair schemes can comply with an abridged approval process as set out in Chapter 9 and can submit the Short Form for the PARR Proposal as outlined in Appendix B.

2.7 Minor Pavement Repair Schemes

Minor pavement repair schemes are typically those with an estimated cost less than €200,000 (excluding Vat).

Minor pavement repair schemes can comply with an abridged approval process as set out in Chapter 9 and can submit the Short Form for the PARR Proposal as outlined in Appendix B.


Page 8

3. Selection of PARR Schemes

3.1 Selection of Priority Schemes for Implementation

In order to obtain the maximum value from investment in PARR across the Network, determination of the highest-priority pavement repair/renewal projects will be undertaken by TII NM, based on an analysis of the PAMS.

Analysis of the data contained in the PAMS is examined against a series of deterioration models to determine the likely intervention required to preserve or enhance the asset and the timeframe within which intervention is required to prevent significant further deterioration. The PAMS is used to determine PARR priorities and recommends the appropriate intervention taking account of the overall budgetary constraints. Potential interventions, treatments and the technical objective of carrying out the PARR works are detailed in AM-PAV-06050.

3.2 Notification for the Development of a PARR Scheme

As outlined in Figure 2.1, TII NM will notify the relevant IA of sections of the national road network for priority development into PARR Schemes by the IA, who will be required to carry out data collection and to develop a PARR Proposal for the approval of TII NM. The IA and their Designer are encouraged to confirm the objectives of the scheme with TII NM at an early stage in the process.


Page 9

4. Data Collection

4.1 Data Collection

Delivery of a successful PARR scheme requires the collation and examination of a wide range of data.

4.2 Information available from PAMS

All relevant survey data stored within PAMS will be made available to the IA by TII NM. This information will normally include the following road condition parameters:

a) International Roughness Index (IRI).

b) Rut depth and crossfall.

c) Surface texture.

d) Cracking.

A detailed description of the information available from PAMS data is presented in Chapter 2 of AM-PAV-06050.

PAMS does not identify the root cause of the defects. The cause of the defects should be confirmed from the data collection exercise which should provide the information for the definition of the scheme specific objectives.

A check list of the typical data sources for the PARR Schemes including structural evaluation is given in AM-PAV-06050. This check list is provided as guidance, and the IA should consider other data sources as appropriate to provide complete information for the preparation of proposals and design.

For guidance on pavement surveys and the detailed investigation of the causes of pavement deterioration, also refer to AM-PAV-06050.

4.3 Utility Surveys

On behalf of the IA, the Designer should carry out the necessary liaison with utility companies and other service providers (e.g., electricity, telecommunications, water, wastewater, gas, cable, broadband etc.) and prepare mapping and records and conduct surveys as necessary to establish the nature and extent of utility, plant and equipment affected by the Scheme.

Utility installation, repairs and diversion work, whenever possible, should be programmed to be completed in advance of any pavement repair and renewal works.

4.4 Acquisition of Mapping/Topographical Surveys

Prior to the commencement of the detailed design of a PARR Scheme, all available mapping should be updated and topographical surveys carried out along the scheme. Where appropriate these can be used to create a digital terrain model and to generate cross-sections and longitudinal profiles. Particular care should be taken to accurately record pavement levels, road markings and signage.


Page 10

5. Pavement Asset Repair and Renewal Proposal

5.1 Preparation of the PARR Proposal

The PARR Proposal will take the form of a report and shall adopt the headings listed in the Report Template provided in Appendix A. The proposal shall include a preliminary schedule of Works.

The IA is responsible for determining the underlying cause of the deterioration, setting the scheme specific objectives and proposing the detailed scope of works to be undertaken. Guidance on the Pavement Assessment, Repair and Renewal Principles is set out in AM-PAV-06050 which sets out the requirements for the scheme level surveys and investigations, data interpretation, treatment options and repair and renewal works.

The engineering solutions proposed must seek to obtain the best value for the investment taking into account the root cause and life cycle costs.

Innovative or unusual pavement asset repair or renewal proposals may require further studies, investigation and/or specialist reports in addition to the PARR Proposal and specific requirements in this regard should be agreed with TII NM.

5.2 Exceptions to the PARR Proposals

Emergency pavement repair schemes referred to in Section 2.6 and minor pavement repair schemes referred to in Section 2.7 can submit the Short Form for the PARR Proposal as outlined in Appendix B.

5.3 Approval of the PARR Proposal

The PARR proposal shall be submitted to TII NM for approval under Gateway No. 1.


Page 11

6. Consent for Award of Contract

6.1 Preparation of Tender Documents and Procurement

The IA shall procure the construction of the PARR Scheme in accordance with relevant procurement procedures and subject to the consent requirements of Gateway No. 2 of Figure 2.1.

Instructions

This Appendix provides a template for the PARR Report which is shown in Table A.1. This Table sets out the main headings for the Report and a short commentary on each Chapter and Appendices for the Report.

The outline shown in Table A.1 should not be regarded as prescriptive nor should its contents be regarded as exhaustive. The IA is expected to have considered all of the headings and to demonstrate such consideration by developing the heading, or stating that it is not relevant and why. The PARR reports only need to be as complex and comprehensive as the proposed works dictate.

All text should be well written and concise as these records will be the key reference to those undertaking future maintenance works.

Report

The Report will be submitted to TII and guidance on the completion of each field is provided in the Pavement Asset Repair and Renewal Proposal Template in Table A.1.

Table A.1 Pavement Asset Repair and Renewal Proposal Template

Chapter/ Appendix

Outline and Commentary

0 Name of Scheme/Scheme Number

1 Introduction Outline the Scheme and summarise the key objectives.

2 Site and Location Include a layout drawing showing the location of the scheme in the National Context and a scheme drawing at a maximum of 1/2500 scale.

5 Objectives of the PARR Proposal

Set out the key objectives of the PARR proposal - is it a structural or surface improvement, etc. How does this compare with the interventions/treatment recommended by the PAMS?

PAMS can identify the symptoms in terms of pavement distress but it does not identify the underlying cause of the pavement deterioration. The Designer must fully understand the causes of pavement distress and deterioration and propose a range of options which will address the underlying causes of the failure of the pavement including inadequate drainage.
