如何完善沥青路面结构设计保证车辆行驶安全的探讨

Probe into How to Improve the Structural Design of Asphalt Pavement to Guarantee Traffic Safety

沥青路面的病害直接威胁着公路通行车辆行驶安全,沥青路面的结构设计不合理是导致路面发生病害的重要原因之一。通过对高速公路沥青路面的主要病害成因从设计角度进行分析,提出应从完善路面设计基础数据的测试与确定方法、合理选择原材料、采用合适的矿料级配、完善配合比设计方法、合理选择沥青面层厚度、加强沥青面层层间及与基层的粘结等途径完善沥青路面结构设计,以进一步提高沥青路面的使用功能,减少道路交通安全事故的发生。

Defects on asphalt pavement directly threaten safe driving of the vehicles; the irrational structural design of the asphalt pavement is one of the key causes of such defects. The causation of main defects is analyzed from the view of design and improvements are suggested from the structural design, such as the test and determination of basic data of pavement design, rational selection of raw materials, adopting appropriate aggregate sizes, improving blend design method, rational selecting the thickness of asphalt layer and reinforcing the binding between the asphalt pavement layer and the base layer to further improve the operational function of the asphalt pavement and reduce the occurrence of traffic accidents.
