摘要
道路病害主要表现在路面破损上,其原因是路面结构本身强度不足,在行车荷载反复作用下产生破损;另外是由于路基稳定性不足,将各种病害反射到路面结构上,使路面产生破损。本文通过对哈尔滨市区道路调查,得出了路面状况指数(PCI)值与路基土含水量,分析路基稠度与路基回弹模量之间的关系,得出影响道路状况的具体因素,为寒区城市道路病害的防治提供指导和依据。
Road disease mainly show up in pavement damage,but the reasons are mainly in two:one is the lack of strength of pavement structure,damaged with a repeated traffic loading;the other is the shortage of subgrade stability and various diseases reflect to the pavement structure so that damage is caused.This paper based on the survey of Harbin urban road gets relationship between the pavement condition index(PCI) and the water content of subgrade soil,and the relationship between consistency of subgrade and subgrade resilient modulus,finally achieves the factors which affect the pavement condition so that it provides basis and guidance to urban road diseases prevention in cold regions.
