摘　　要：SEAM沥青混合料具有降低施工温度、节约沥青用量、提高高温稳定性等优点,通过马歇尔、车辙、低温弯曲和冻融劈裂等试验对不同级配类型不同掺量SEAM沥青混合料性能进行全面评价,并指出不同掺量SEAM沥青混合料的适用条件。结合单轴压缩试验数据(圆柱体法),推荐不同级配类型不同掺量的SEAM沥青混合料抗压回弹模量回归曲线,为SEAM沥青混合料推广使用时提供设计参数。The SEAM asphalt mixture had the advantages of reducing construction temperature, saving asphalt content, improving the high temperature stability, etc. With different gradation type and different SEAM mixing amount, the performances of SEAM asphalt mixture were evaluated by Marshall, rutting, freezing cold bending and splitting and other tests, pointed out the applicable conditions of asphalt mixture with different dosage of SEAM. Based on the data of uniaxial compression test, compression rebound modulus regression curves of asphalt mixture with different gradation type and different SEAM mixing amount were recommended, and offered design parameters for the promotion of SEAM asphalt mixture.
