摘要
为了满足浇筑式沥青混凝土对沥青结合料的特殊性能要求,通过对不同掺加比例的橡胶粉复合改性沥青的性能进行试验分析,确定了最佳橡胶粉掺量,并对橡胶复合改性沥青在不同温度下的粘度进行了测试,以说明橡胶粉加入到浇筑式沥青混凝土中不会影响其施工流动性.分别采用橡胶粉复合改性沥青和岩沥青复合改性沥青作为浇筑式沥青混凝土,在高、低温时,对其性能进行了对比.试验结果表明:采用橡胶粉复合改性沥青作为浇筑式沥青混凝土用沥青结合料,可以达到同等材料使用要求,是可行的.
In order to meet the special requirements for asphalt binder of gussasphalt, performances of composite rubber crumb-based modified asphalt and gussasphalt con- crete with different rubber crumb content were experimentally studied to determine the optimum rubber crumb dosage, and the viscosity of composite rubber crumb-based modified asphalt at different temperatures were tested. The results show that the addi- tion of rubber crumb into gussasphalt concrete would not influence its construction flu- idity. Comparative research was done for the high and low temperature performances of composite rubber crumb-based TJhe results also show that it is as the asphalt binder of gussasp modified asphalt and composite rock modified asphalt. feasible to use the rubber crumb-based modified asphalt halt concretes.
