Preparation of the composite asphalt material and its performance in road rehabilitation

Asphalt materials have a very wide range of applications in roads, but with the increase traffic pressure and intensification cracking rutting traditional asphalt pavements, there is an urgent need to further improve performance materials. In this paper, composite containing 10%, 20%, 30% trinidad lake (TLA) 0%, 2%, 3%, 4% styrene-butadiene rubber (SBR) were prepared. Their basic properties mixes used for road rehabilitation analyzed. It was found that addition TLA SBR caused decrease penetration degree material, significantly increased softening point detrimental ductility could ductility. From analysis mixes, comprehensive 20% TLA+3% good, its dynamic stability reached 3,712.66 times/mm, water also stiffness modulus 3,332.64 MPa. The results prove improvement performance, method can be applied practical projects.
