摘　　要：动态模量(AMPT)一般用来评价沥青混合料的材料性能,常作为沥青混合料设计、沥青路面设计和评价分析的参数。选取青银高速公路不同罩面结构层、不同罩面材料、不同罩面时间的代表路段钻芯取样,进行室内AMPT试验,并对动态模量指标和流动度指标进行分析,旨在通过检测在役期路面沥青结构层的动态模量来评价其使用寿命,为养护罩面的时机提供数据支持。The dynamic modulus(AMPT)is generally used to evaluate the material property of asphalt mixture,which is often used as the parameter of asphalt mixture design,asphalt pavement design and evaluation analysis.Core drilling samples of representative sections with different structural layers,materials and time of overlays of Qing-Yin expressway are selected.The indoor AMPT test is carried out,and the dynamic modulus index and fluidity index are analyzed,so as to evaluate the service life by testing the dynamic modulus of asphalt structure layer of pavement during the period of active service,and provide data support for the timing of the maintenance overlay.

关 键 词：养护罩面 动态模量 使用性能 流动度
