沥青路面水损害机理分析及对策研究

Mechanism Analysis and Countermeasures of Water Damage of Asphalt Pavement

沥青混凝土路面积水容易因内部集料的黏结性较低而发生离析,在行车荷载的作用下,路面易发生整体破坏。基于此,论文对水损害的成因及表现类型进行调查分析,通过马歇尔稳定度试验分对沥青混合料水敏感性进行析,结合工程案例,对抗水损害的具体措施进行探讨。

The water in asphalt concrete pavement is easy to segregate because of the low bonding property of the internal aggregate.Under the action of driving load,the pavement is easy to be damaged as a whole.Based on this,the paper investigates and analyzes the causes and manifestations of water damage,analyzes the water sensitivity of asphalt mixture through Marshall stability test,and discusses specific measures to combatwater damage combinedwith engineering cases.
