Process and composition for constructing hydraulically bonded road foundations or semirigid roadway structures.

摘要

According to the invention when building hydraulically bonded road foundations or semirigid roadway structures with known operations or when producing the material of road foundations, in addition to the usually applied hydraulic binding material, and to the usual additives, 50-150 kg/m<3> of granular plastic material of 1-15 mm, preferably of 5-10 mm, particle size and of a specific surface of 6.0-0.2 kg/m<2> is added to the material of the road foundation. The process can be performed by preliminary blending of the components or by admixing the grained plastic material to the existing soil or to the mineral material transported there and laid out on the site of the road building.
