摘要
温拌沥青混合料在道路工程中应用广泛,为了研究温拌剂对沥青混合料压实特性及力学特性的影响,以AC-20型沥青混合料为研究对象,测试不同压实条件下混合料的密度及力学性能。室内试验结果表明:温拌剂可以降低沥青混合料压实温度及所需的压实功,改善混合料的压实性能,可以提高沥青混合料的高温性能,降低沥青混合料的低温性能,对水稳定性影响不大。
Warm mixing asphalt mixture is widely used in the road.In order to study the influence of warm mixing agent on the compaction characteristic and mechanical property of asphalt mixture,the density and mechanical properties of mixtures under different compaction conditions are tested by taking AC-20 asphalt mixture as the research object.The laboratory test results show that:the warm mixing agent can reduce the compaction temperature of asphalt mixture and the required compaction effort,improve the compaction performance of mixture,improve the high temperature performance of asphalt mixture,and reduce the low temperature performance of asphalt mixture.The influence on the water stability is not large.
