为研究橡胶粉改性沥青混合料及其路用性能,基于实体工程,对橡胶粉的改性机理进行了分析,并对间断级配橡胶粉改性沥青混合料进行了配合比设计,在此基础上,对间断级配橡胶粉改性沥青混合料的路用性能进行了验证,试验结果表明,利用废旧橡胶粉对沥青进行改性,能够有效提升沥青的粘结性能与温度敏感性能,其成型的间断级配沥青混合料具有优良的路用性能。
In order to study the rubber powder modified asphalt mixture and its road performance, based on the physical engineering, the modification mechanism of the rubber powder was analyzed, and the compounding ratio design of the rubber powder modified asphalt mixture was carried out. Based on this, , The road performance of intermittent graded rubber powder modified asphalt mixture was tested. The results show that the use of waste rubber powder modified asphalt, asphalt binder can effectively improve the performance and temperature-sensitive properties, the molding The discontinuous grade asphalt mixture has excellent road performance.
