摘要:
为了研究橡胶沥青混合料的和易性与压实特性之间的关系,采用Superpave旋转压实仪和自行研制的和易性测试设备,测试了不同温度下的压实特性与和易性,并推荐了不同胶粉掺量所对应的适宜压实温度与胶粉细度.结果表明,当胶粉掺量为25%时,胶粉细度对橡胶沥青混合料压实过程的影响最为显著.当压实温度为190 ℃时,胶粉掺量对橡胶沥青混合料压实过程的影响最为显著.当胶粉细度为80目时,压实温度对橡胶沥青混合料压实过程的影响最为显著;橡胶沥青混合料的和易性越好,压实性能也越好.当胶粉掺量为5%和15%时,所推荐的适宜压实温度与胶粉细度分别为160 ℃和40目;当胶粉掺量为25%时,所推荐的适宜压实温度与胶粉细度分别为160 ℃和20目.
Abstract:
To study the relationship between workability and compaction property of rubber asphalt mixture, the Superpave gyratory compactor(SGC)and the self-developed workability test equipment were used to test the workability and compaction property of rubber asphalt mixture at different temperatures. The appropriate compaction temperatures and the powder fineness corresponding to different powder dosages were recommended. The results show that, when the powder dosage is 25%, the powder fineness has the greatest influence on the compaction process. When the compaction temperature is 190 ℃, the powder dosage has the greatest influence on the compaction process. When the fineness is 80 mesh, the compaction temperature has the greatest influence on the compaction process. The better the workability of rubber asphalt mixture, the better the compaction property. When the powder contents are 5% and 15%, the recommended compaction temperature is 160 ℃ and the powder fineness is 40 mesh. When the powder content is 25%, the recommended compaction temperature is 160 ℃ and the powder fineness is 20 mesh.
