Process Parameters of Rubber Powder Particles Modified Asphalt

Abstract:

A new type rubber powder particle modifier can be produced by adding some performance improvement additives into normal 40-60 mesh rubber powder, and re-granulation, it mixed well with the base asphalt, having less airborne dust and better performance. 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 the dosage of rubber powder in the process of producing rubber powder particles modified asphalt, determining the optimal process parameters, and the road performance indicators of the modified asphalt mixture has been verified.
