摘要
高速公路沥青混凝土路面表层直接承受车轮荷载作用 ,并且长年累月经受阳光、温度、空气和雨水等大气因素的影响 ,为此沥青混凝土路面表层必须具有综合的路用性能 ,而我国现有的各种表层级配范围比较宽松。在 AC16、AK16和 SMA16等级配范围基础上 ,通过试验为临长高速公路沥青混凝土路面提出了具有综合性能的表层级配范围并进行了相应的试验验证。
The top layer of asphalt concrete pavements bears wheel function of loading directly, and moreover it withstands the influences of sunshine, temperature, air and rainwater,etc.year in year out. For this reason, the top layer of asphalt pavements must has comprehensive performance,but in China the existing various graded kinds of out-layer can't meet the request.On the basis of the gradations of AC16,AK16,SMA14 the gradation with comprehensive performance are presented and the corresponding verification carried out by tests.
