摘要
以鄂西南恩施、长阳、五峰等地服役5年以上的3条山区道路为研究对象,通过调查分析确定了鄂西南山区道路的主要病害类型及其成因。结果表明,不规则网状开裂、坑槽、沉降变形为鄂西南山区道路的主要病害类型;不规则开裂源于沥青路面服役期间的老化,坑槽的产生与山区道路坡度大、受水损害严重有关,路面局部沉降变形或塌陷则主要与山区岩溶地质的发展有关。
The main road diseases and their causes were determined in this research based on a survey of three mountain roads located in the southwest of Hubei province including Enshi,Changyang and Wufeng etc,which have served over five years.Results suggest that irregular reticular cracks,potholes and local subsidence deformation or road collapse are the main disease types of mountain roads located in the southwest of Hubei province.The aging of asphalt pavement should be responsible for the irregular reticular cracks.The potholes are due to the contributions of big road slope and serious water damage.The local subsidence deformation or road collapse is mainly related to the development of karst geology.
