中文摘要：

基于单轴贯入试验和无侧限抗压强度试验,得出了乳化沥青冷再生混合料在常温和高温条件下的抗剪强度、黏聚力与内摩擦角等抗剪特性参数,分析了水泥质量分数、乳化沥青类型及其质量分数、沥青旧料掺量对抗剪性能的影响规律,并进行了有限元计算和室内车辙试验研究.结果表明：随着水泥质量分数增加,乳化沥青冷再生混合料各抗剪指标均有增加,当水泥质量分数为0-1.5%时增幅明显;乳化沥青质量分数增加后,抗剪强度降低,相比于常温条件,高温条件下乳化沥青质量分数影响更显著;乳化沥青类型对抗剪参数影响不明显;沥青旧料掺量降低后,抗剪强度、黏聚力指标均明显提高,但内摩擦角基本不变;基于层变形叠加的永久变形通用模型应用于乳化沥青冷再生混合料变形预估时,需要进行修正,修正后具有较高的准确度.

英文摘要：

Based on the uniaxial penetration strength test and unconfined compressive strength test,shear strength,cohesion and inner friction angle of the cold recycled mixture with emulsified asphalt were determined under the conditions of room temperature and high temperature. The effects of cement mass fraction,characteristics and mass fraction of emulsified asphalt and reclaimed asphalt pavement（ RAP）content on shearing properties of cold recycled mixture were analyzed. The permanent deformation was investigated by the finite element method and rutting test. The results show that all the shearing indexes are increased with the increasing of cement mass fraction,especially obvious for the cement mass fraction from 0 to 1. 5%. The shearing indexes are decreased with the increasing of emulsified asphalt mass fraction, and there is significant impact on the shearing properties at high temperature. The characteristics of emulsified asphalt have no obvious effect on shearing properties. The shear strength and the cohesion are improved obviously with the decreasing of RAP content,while the inner friction anglehas no effect. The permanent deformation model applied for predicting the deformation of cold recycled mixture with emulsified asphalt should be further revised to obtain more improved precise.
