基于突变理论的沥青路面使用性能的评价

摘要

为准确的对沥青路面使用性能进行评价,建立了以突变理论为基础的性能评价模型,该模型考虑了路面状况指数,舒适性指数,结构强度指数和横向力系数4个主要指标.突变理论模型利用突变理论在多准则评价决策中的优点,解决了传统评价模型由人为确定评价指标权重的缺点,更能真实准确地反应路面的使用性能.首先将各底层评价指标进行规格化计算,再利用归一化公式计算出PQI,从而对沥青路面的使用性能进行评价.通过实例证明了该方法的可行性、可靠性,为沥青路面使用性能的综合评价提供了一种新的思路.%In order to more precisely evaluate the asphalt pavement performance, the catastrophe theory performance evaluation model was established, in which the four main indicators (PCI. RQI. SSI and SFC) of asphalt pavement performance were considered. By using the advantages of catastrophe theory over the multiple criteria decision, the disadvantages of the subjective evaluation was solved, and the real performance of the pavement can be more accurately reflected. At first, the base index should be normalized, and then the normalized formula was used to calculate the PQI, which is used to evaluate the performance of the asphalt pavement. The method has been proved feasible and reliable by examples, and will provide a new way for the asphalt pavement performance evaluation.
