伴随着我国城市建设的快速发展,运营多年的道路面临着车行道及人行道破损严重,对周边的服务功能不断减弱,严重制约沿线区域的经济发展,因此必须进行升级改造。本文结合具体的工程实例,重点对路面病害调查、车行道人行道改造方案及雨污水改造进行了全面的介绍。 Along with the rapid development of urban construction in China, the roads that have been operating for many years are facing serious damage to roadways and sidewalks, the continuous weakening of the service functions in the surrounding areas and serious constraints on the economic development along the line. Therefore, upgrading and reconstruction must be carried out. In this paper, the specific engineering examples, focusing on the pavement disease survey, the sidewalk renovation program and the rainwater and sewage to carry out a comprehensive introduction.
