FIELD: construction. ^ SUBSTANCE: invention relates to the field of road construction and may be used to improve construction and development of roads with high adhesive and bearing properties, which occur when using the proposed method. The method of road construction with a solid surface includes the following: at first design is carried out, then routing is performed, and soil is excavated for the depth of 0.8-1.2 m, then the route bed along side slopes is strengthened with reinforced concrete piles with height of Hpile=Gs.Hroute, where Gs. -golden section: 1.61, Hroute - route depth, and a metal grid is fixed to them along the entire height with a certain overlap, equal to the height of reinforced concrete piles, and this overlap is rigidly fixed to the surface of the road bed by any available method, then sand is filled into the produced road bed for the height of 0.4-0.6 m, compacted for the depth of 0.2-0.3 m, then find crushed stone of 3-4 cm is filled for the height of 0.5-0.7 m, then it is compacted, further coarse crushed stone of 6-9 cm is filled with thickness of 0.4-0.6 m, compacted, then find sand is filled onto the surface of coarse crushed stone, and the entire surface of the road is processed with rammers, until sand fills the space between coarse crushed stone for a half, then the remaining space is poured with melted liquid glass between coarse crushed stone, and liquid glass appears on top with a layer of 2-3 cm, and then sand is filled on it with average particle size of 3-5 mm, and then the road surface is compacted with simultaneous removal of unfixed sand, besides, all operations, starting from compaction of the lower layer of sand is carried out with formation of an inclination from the road centre to both sides of at least 2-5%, and further the section is left for cooling for 2-3 days, then for a day the water surface is poured with water. ^ EFFECT: method makes it possible to produce a road surface of high adhesive and bearing properties. |
