沥青路面水损害的因素分析及预防对策

Analysis, Prevention and Countermeasures on Water Damage Factor of Asphalt Pavement

分析了沥青路面水损害的主要病害存在形式和特征,并总结了造成沥青路面水损害的主要机理和影响因素,说明:降雨是水损害的直接原因,沥青混合料材料本身特性是内在因素,而车辆荷载作用是病害形成的直接诱因。为了进一步降低沥青路面水损害的发生,提高沥青路面结构的长期使用性能和行车安全性能,可以从优化路面排水设计和改善沥青混合料材料选择两个方面进行预防。

The article analyzes the main water damage type and feature of asphalt pavement, and summarizes the main mechanical mechanism and influence factors of water damage on the asphalt pavement. The result shows that the rainfall is the direct cause to water damage, the material properties of bituminous mixture is the inherit factor, and the vehicle load effect is the direct incentive to cause the fault. In order to further reduce the cause of water damage on asphalt pavement, and to improve the long-term service life and driving safety of asphalt pavement structure, there are two aspects of optimizing the pavement drainage design and improving the asphalt mixture materials for prevention.
