… m2, excavation and engraving in the amount of 594,05 m3, with transport of excavated material up to 5 km and removal of excess for disposal, and making embankments in the amount of 181,00 m3. The embankments should be made of material obtained by the Contractor, with density and wetting of subsequent layers. The surface of the roadway and borders. Milling or demolition of the asphalt surface over an area of 1 178,00 m2 is planned, with an average depth of 10 cm, and cutting of the surface over a length of 300,00 m. Asphalt demolition material is subject to removal and becomes the property of the Contractor. The surface includes an AC16 leveling layer with a thickness of 4 cm on an area of 1178,00 m2 and an AC11 abrasive layer with a thickness of 4 cm on an area of 1159,00 m2, for the KR3 movement category. The frames include 15 × 30 cm concrete curbs on the C12/15 concrete bench and 8 × 30 cm concrete bench edges on the C12/15 concrete bench. Sewage should be made of gray Holland concrete cube with a thickness of 8 cm, on a cement-sand ballast with a thickness of 15 cm, with sand filling of welds. Walkway and descents. Once the substrate has been profiled and compacted, a layer of improved substrate is expected to be made of a 15 cm C1.5/2.0 cement-bonded base and a 15 cm C90/3 non-aggregate base with a 0-31.5 mm grain size and a 15 cm thickness. The surface is a colorful concrete cube of Behaton type with a thickness of 8 cm, laid on a cement-sand ballast, with joints filled with sand. the bus bay. The structure includes a contoured and compacted substrate, a layer of improved C3/4 cement-bonded substrate with a thickness of 25 cm, a non-aggregate C90/3 base with a grain size of 0-31,5 mm and a thickness of 35 cm, and a surface of 8 cm thick Behaton grey concrete cube on a cement-sand ballast, with sand-filled welds. The thicknesses of the layers are given after compaction, in accordance with the descriptions of costing items. Finishing works and drainage. The range includes the demulsion and profile of ditches, the strengthening of slopes with a palisade of 16.5 × 16.5 × 120 cm and openwork slabs 60 × 40 × 8 cm on 8 cm thick cement-sand ballast, the humbling of slopes and the height adjustment of water, gas and sewage fittings. Passes under the exits should be made of PVC-U or PP pipes with a diameter of 500 mm, class SN8, connected to rubber seals, on a bench of broken aggregate 15 cm thick, with prefabricated front walls with wings.
