Complex-Modified Road Asphalt Polymer Sulfur Concrete Micro-Reinforced with Chrysotilassbeth Fiber
Abstract: For the complex-modified asphalt polymer sulphur concrete micro-reinforced with chrysotile-asbestos fibers of grade A-6K-30, the optimal temperatures were established: laying 140...155 °C; compaction 60...130 °C, which in turn increases the construction season and the transportation distance of the asphalt mix. Modified asphalt polymer sulphur concrete mixtures are characterized by lower specific compaction energy 0,95 j·m3/kg vs 1,27 j·m3/kg for hot asphalt mixes. Modified asphalt polymer sulfur concretes are characterized by higher performance properties than hot asphalt concretes: Marshall resistance 26.83 kN versus 15.26 kN, coefficient of heat resistance in the temperatur range during compression 3.6 versus 6.5; compressive strength at 50 °C 2.2 MPa > 1.2 MPa; coefficient of water resistance at long-term water saturation 1.0 > 0.85. Rigidity according to I. A. Rybiev increases 12 times, which indicates the ability to resist stresses that lead to plastic deformations.
Keywords: road asphalt polymer sulfur concrete micro-reinforced with chrysotile-asbestos fibers, technological properties, deformation-strength characteristics, durability.
