该文将路面破损按历时性分为自然破损和病害破损,提出了路面使用性能自然衰减率概念,研究了其与路面损坏状况定期普查数据之间的关系。对路面损坏状况定期调查数据按照调查历时进行评价分析,得到了沥青路面养护效果与路面损坏状况的关系,据此初步建立了养护效果的历时性评价方法,可以尝试用于分析路面养护效果的有效性以及路况变化趋势的定性预测。
In this paper, the damage of pavement is divided into natural damage and disease damage according to the timeliness. The concept of natural attenuation rate of pavement performance is put forward. The relationship between pavement deterioration and periodic census data is studied. The regular survey data of pavement damage status were evaluated and analyzed according to the survey duration, and the relationship between the pavement maintenance effect and pavement damage status was obtained. Based on this, the diachronic evaluation method of maintenance effect was preliminarily established, which could be used to analyze the pavement maintenance effect effectively Qualitative and predictive trend of the change of road conditions.
