摘要
为了确定水泥混凝土路面预防性养护时机,基于路面损坏状况指数PCI与路面平整度关系构建模型,借助模型找到路面损坏状况指数加速度最大值,从而确定预防性养护时机。最后给出实例进行了验证。
In order to determine preventive maintenance timing,a new model is made based on pavement condition index & roughness index(PCI-IRI) function model,by which the maximum accelerating speed of pavement condition index(PCI) can be found,and then preventive maintenance timing can be identified at this point.Finally an example is presented to verify the model.
