摘要
比选路面预防性养护措施和确定其实施时机是路面预防性养护技术的核心。在已有路面性能衰变模型的基础上,通过引入改善系数A和寿命系数B,建立了预防性养护后的路面性能衰变模型,并讨论了改善系数A和寿命系数B的内在含义;进而提出了利用该衰变模型和费用效益比最大为准则的选择预防性养护措施和确定其实施时机的方法。
The selection of treatment measures and determination of time are the key procedures of pavement preventive maintenance technique, with reference to existing deterioration model on pavement functions, by introducing parameters A and B, an updated deterioration model on pavement functions after undertaking preventive maintenance is established, and the meanings of parameters A and B are discussed, therefore the selection of treatment measures and determination of time for preventive maintenance based upon the deterioration model on pavement functions and maximum cost-benefit ratio are put forward.
