【摘要】 为了解决沥青路面存在的泛油、坑槽、车辙、推移、低温裂缝等问题,有必要研究沥青路面的高温稳定性,从而改善路面结构的使用性能,减轻路面结构的损害。通过马歇尔试验和车辙试验对三种沥青混合料进行了高温稳定性试验,同时分析了影响沥青混合料马歇尔稳定度和动稳定度的因素并从集料、沥青、设计和施工几个方面对提高沥青混合料高温稳定性的途径进行了探讨。更多还原

【Abstract】 In order to resolve problems such as overfull asphalt, process and rut occur on the heavy-duty roads and improve the application performance of asphalt pavement, it is necessary to study the high temperature stability of asphalt mixture. Marshall stability tests and rut formation tests are carried out to test high temperature stability of three types of asphalt mixtures. Factors that influence Marshall stability and dynamic stability of asphalt mixture are analyzed and suggestions to improve high temperature stability from aspects of aggregate, asphalt, design and construction are given.更多还原
