All work must be carried out in accordance with the project, this technical conditions and JUS U.E1.010 - earthworks on the construction of roads. The material

To create of embankment will be used all inorganic materials of prescribed quality. In the embankments can not be incorporated organic debris, roots, sod, or material that over time, due to biochemical activity, changes their mechanical and physical properties. Building materials for the embankment may be obtained from carve. Regulations on which is controlled quality of materials • JUS U.B1.010 – sampling • JUS U.B1.012 - determining of soil moisture • JUS U.B1.014 - determination of specific gravity • JUS U.B1.016 - determination of volumetric weight • JUS U.B1.018 - determination of granulometric composition • JUS U.B1.020 - determination of consistency limits • JUS U.B1.024 - determination of combustible and organic materials • JUS U.B1.038 - determination of optimum water content. Determination of organic and combustible materials, and application of soil volume, should be done only in specific cases (hazardous materials). In examining the suitability of earth materials for construction of embankments, examine your of material from each carve and each change of material. Experiments should be conducted at minimum two samples for each type of material. Classification of materials For the classification of materials used for of embankments will be used unique terminology according to classification USCS and AASHO and Casagrande's plasticity chart. Preliminary tests of materials for embankment In examining the suitability of earth materials for construction of embankments should be examined all materials from carve and borrow pits with the coherent soil, including coherent materials in mixed materials. It is necessary to perform the following tests: 1. Proctor procedure to examine all the gravity, optimum humidity and actual humidity. It is required the minimum bulk density of subsoil and embankment to a height of 3.0m 15.0 kN/m3, for height of embankments over 3.0m kN/m3 15:50, and the bedding16:50 kN/m3 , and sand can be used after evaluating their suitability for bedding, if is bulk density of less than 16:50 kN/m3. 2. Examine the grain size distribution and the degree of inconsistency. 3. Examine Atterberg consistency limits; yield strength, rolling limit, plasticity index and Casagrande's criterion to frost. 4. Based on the front, to determine the group index (Ig) 5. Establish a California laboratory index of soil bearing capacity (CBR) according to JUS U.B1.042. Two previous trials should be addressed through the project in geo-mechanical report.

The criteria for judging the quality of materials before incorporation

67

• Moisture content should be such that the compression can achieve the prescribed quality, close to optimal. • Minimum bulk density achieved in the laboratory with the energy E = 60MPm/m3 should amount for embankments up to 3 m - 15.0kN/m3 for embankments over 3 m - 15.50 kN/m3 • The optimum humidity should be less than 25% • Limit flow should be less than 65% • Plasticity Index should be less than 30% • The degree of inconsistency "In the" should not be less than 9 • The content of organic matter should be less than 10 • If the mound for the incoherent material, grain size must not exceed 30cm and a maximum of 10% of 40 cm • For embankments can be used materials of proven stability of the roadbed. In examining the suitability of earth materials for construction of embankments, finish the examination of material from any cuts and borrow pits, and at each change of material. Experiments should be conducted at minimum two samples for each type of material. The above tests must be carried out if there are geo-mechanical testing data in the project. Capture and filling Capture and filling of materials is prepared based on the ground, or already constructed layer of embankments, can begin only after the supervisory body take over the lower layers. Each individual layer must be outspread in the longitudinal direction, horizontally, or up a slope equal to the projected longitudinal slope. In the cross terms, each layer must have a slope-sided, 2 to 5%. The slope is required for storm water drainage, causing surface layer incorporation of coherent earth materials, shall be immediately compacted and compacted (daily). Each individual layer must be filled according to the projected cross section. In capture passes of the means of transportation should be more evenly distributed across the entire width of formation. Compaction Each layer of embankments shall be compacted in full width by suitable mechanical means, while compaction must be generally done from the edge towards the center. All places inaccessible for mechanization or places where the use of heavy compaction plant is unsuitable for other reasons (filling in behind the building, retaining walls, etc.) must be compacted by other suitable means or methods whose use will be approved by supervisory authority,. Each layer of embankments must be moistened before compacting or dried to moisture, which is consistent with previous studies, in which the types of materials can be used to recharge the required density, with each layer of embankments to be chopped by machine. If after compaction and quality control are not immediately continue with the next layer of filling, but will continue filling with longer periods of time, under different weather conditions, before filling up again must be monitored the quality of compaction. Development in this case can only begin when it is again demonstrated by test the quality of compaction. Filling must be performed so that the layers in the longitudinal sense, are preferably horizontal, and so avoid sudden high altitude passes between layers of different heights, and performed by incline, where more can be carried out, the proper compaction.

68

The work on filling up will be terminated at any time when it is not possible to achieve satisfactory results, especially because of rain or other atmospheric elements. On this ground, Contractor is not entitled to any compensation. of embankments The material shall not be installed on frozen surfaces, nor shall be mounted on snow and ice. Regulations governing the quality control of installation • JUS U.B1.010 – sampling • JUS U.B1.012 - determining of soil moisture • JUS U.B1.016 - determining the volumetric weight of soil • JUS U.B1.046 - compressibility module circular plate The volume of running control testing Compaction of embankments layers is examined every 50-100 m with the two experiments in the immediate vicinity, which give a result. This applies for embankments less than 50 m. Moisture content is tested daily. Preparation of the next layer can not be accessed until proven quality required of the previous layer. Receiving of installed material Reception of each layer of embankments shall be carried by supervisory authority in accordance with prescribed criteria. All deficiencies identified in relation to the listed quality conditions the Contractor must repair or remove. Measurement Quantity of the incorporated material is measured in cubic meters per actually executed quantities under the project, including the bank's core. Payments Quantities are paid according to the contracted price for 1 m3 embankment material embedded. The contract price must include all the works on spreading, wetting and drying, compaction, planning embankments and shoulders with accuracy of ± 5 cm, compared to the projected slope embankment, with all materials and labor, transportation and transfers, and the Contractor is not entitled to requires no premium for making embankment. To replace the of low bearing material in the placenta, in places of cuts and carve applies fully all that is said for replacement of low load-bearing material in the subsoil in the preparation of embankment. Excavation in the bedding and in the subsoil, for replacement of material, shall be paid according to the affected unit price for broad dug on the route of the appropriate categories. Calculation of amount embankment shall be determined by cross-profiles, and this quantity does not enter amount of top soil on slopes and shoulders. The calculation of amount embankment, enters part of embankment which was constructed at the site of the removed humus in the subsoil. If it is excavation of topsoil beneath embankment in the thickness of a higher or lower than projected, based on bills of calculated excess or shortage of topsoil excavation, or surplus or deficit derived embankment.
