针对现行规范中对沥青路面破损面积的评定不够明确等问题,提出修补宽度达到路段宽度时不应参与路面破损状况评价,重新选取修补损坏面积换算系数(K )为0.7；提出一种基于蒙特卡洛算法的 Matlab 检验方法对 K =0.7的合理性进行了检验,先将已有数据输入 Mat-lab 分布拟合,得出影响路况指数(PCI)的修补面积、裂缝总长度、其他破损面积等因素服从的分布函数,进而使用蒙特卡洛算法模拟得出大量数据,计算相应的 PCI,得出路况评价结果。最后通过与实际路况比较和实际工程应用进行检验,证明了 K 取0.7可以得到合理的统计计算破损面积方法。

Aimed at the problems that evaluation of pavement damage area in current standards is not clear enough,a current asphalt pavement condition evaluation model is introduced.If the repair area width rea-ches the pavement width,this should not be involved in pavement damage condition evaluation.Conversion coefficient K of repairing damage area should be 0.7.A Matlab testing method based on Mandonte Carlo al-gorithm is put forward to examine the rationality of K being 0.7.The concrete conditions are as follows:First,input the known data to Matlab to fit,and then,derive the functions of elements obey affected pavement condition index,such as repair area,total crack length and other damage areas,etc.,Last,cal-culate the corresponding PCI to get the result of pavement condition evaluation by using Monte Carlo algo-rithm.Through the comparison with the actual pavement conditions and the actual test,the rationality of K being 0.7 is verified.
