橡胶沥青及其混合料高温性能研究

Research on high-temperature performance of rubber asphalt and its mixture

从橡胶沥青及混合料的高温性能入手,采用针入度、软化点、135℃粘度评价橡胶沥青高温性能,并采用车辙试验分析橡胶沥青混合料的高温性能,试验结果表明:橡胶粉能够显著改善橡胶沥青及混合料的高温性能。

Starting from high-temperature performance of rubber asphalt and mixture,the article estimates high-temperature performance of rubber asphalt by penetrometer,softening point and 135℃ viscosity,and analyzes the high-temperature performance of rubber asphalt mixture by applying wheel tracking test. The experimental results show that：rubber power can improve the high-temperature performance of rubber asphalt and mixture.
