高速公路在车辆荷载和气候环境等因素综合作用下,路面的使用状况趋于恶化,当路面破坏到一定程度时,会给车辆的行驶质量产生很大影响,为了使高速公路路面的使用性能保持在一定水平,给公路的使用者提供经济、快速、舒适的通行条件,就要进行不断的资金投入,如何保持高速公路的使用功能,选择什么可行的技术与合理的经济投入以及路面的养护维护对策,这就需要对路面养护费用与效益进行分析研究。
Under the combined action of vehicle load and climate and other factors, the use status of the road surface tends to deteriorate. When the road surface is damaged to a certain extent, the running quality of the vehicle will be greatly affected. In order to maintain the serviceability of the highway pavement, At a certain level, to provide road users with economic, rapid and comfortable access conditions, it is necessary for continuous capital investment, how to maintain the use of the highway function, choose what feasible technology and reasonable economic input and maintenance of the pavement Countermeasures, which need pavement maintenance costs and benefits of research.
