摘　　要：温拌技术可有效降低橡胶沥青混合料的施工温度,但不同类型的温拌技术对橡胶沥青混合料性能的影响存在明显差异。采用不同类型的温拌剂材料制备温拌橡胶沥青混合料,开展混合料的密实度试验、水稳定性试验、动稳定度试验与动态模量试验。研究表明,各类温拌剂均可有效降低橡胶沥青施工温度,然而Evotherm-DAT温拌剂将导致橡胶沥青混合料的抗水损性能与抗车辙性能降低,石蜡与Asphalt-min温拌剂对橡胶沥青混合料的影响相对较小。The warm mixing technology can effectively reduce the construction temperature of rubber asphalt mixture,but the influence of different types of warm mixing technology on the performance of rubber asphalt mixture is obviously different.Different types of warm mixing agent materials are used to prepare warm mixing rubber asphalt mixture.The compactness test,water stability test,dynamic stability test and dynamic modulus parameter analysis of the mixture are carried out.The research shows that all kinds of warm mixing agents can effectively reduce the construction temperature of rubber Asphalt,but Evotherm-DAT warm mixing agent will reduce the water damage resistance and rutting resistance of rubber asphalt mixture,paraffin and Asphalt-min warm mixing agent has relatively little influence on rubber asphalt mixture.
