沥青面层是直接承受行车荷载作用和大气降水、温度变化影响的路面结构层,应具有足够的结构强度,良好的温度稳定性,耐磨、抗滑、平整和不透水性。现已得到广泛的应用,所以质量已成为今后研究的重点。针对公路沥青面层的结构类型及其各自的特点进行了分析,在实际工程中应根据当地的交通状况、气候条件、降雨量、材料情况、施工工艺、经济造价等因素选择合适的沥青面层类型。
Asphalt pavement is a pavement structural layer that directly receives driving load, atmospheric precipitation and temperature changes. It should have sufficient structural strength, good temperature stability, wear resistance, anti-skidding, smoothness and impermeability. Now it has been widely used, so the quality has become the focus of future research. According to the analysis of the types of asphalt pavement structure and their respective characteristics, the actual asphalt pavement should be selected according to the local traffic conditions, climatic conditions, rainfall, material conditions, construction technology, economic cost and other factors Types of.
