Road Performance Study on Gap-Graded and Dense-Graded of Rubber Powder Particles Modified Asphalt Mixture

Abstract:

A new type of rubber powder particle modifier can be produced by adding some performance improvement additives into the normal 40-60 mesh rubber powder and re-granulation, it proved to have better performances and less airborne dust, mixing well with base asphalt. Researching the performance indicators of rubber powder particles modified asphalt under different process parameters through the adjustment of shear temperature, shear rate, shear time and dosage of rubber powder in the process of producing rubber powder particles modified asphalt, the optimal process parameters was determined, and the road performance indicators of the modified asphalt mixture has been verified.
