摘要
Abstract
To improve the performance of SBS/Waste rubber powder modified asphalt,and resolve the issue of high viscosity and compatibility that caused by conventional rubber powder content at the same time, we studied the influence of different processes and factors on asphalt performance by the single factor experiment and crumb rubber grafting. The results show that the low amount of grafted rubber powder can effectively solve the problem of high viscosity and segregation. The optimal formula is SBS of 2. 5% , grafted crumb rubber of 1. 5% ,sweller of 4% and stabilizer of 16%.关键词
