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。 Asphalt concrete pavement surface of the expressway is directly subjected to the wheel load and is subject to atmospheric factors such as sunlight, temperature, air and rain for many years. For this reason, the asphalt pavement surface must have comprehensive road performance. However, Gradation with a more relaxed range. On the basis of grading of AC16, AK16 and SMA16, the range of surface gradation with comprehensive properties for asphalt pavement of Linfen expressway was proposed and the corresponding experimental verification was carried out.
