Study on the Deterioration of the Pavement viewing from the Road Meintenance Patrol

从公路养护巡查记录的角度出发，对国道和城市快速路的路面老化特征进行了分析。收集了3-6年的路面裂缝、车辙、不平整度、坑槽等基础数据，分析了交通量、路面结构、路面材料、对路面老化的各种指标，尝试用多元回归分析或数量化理论，建立起基于基本因素的路面老化解释模型，并对各种指标进行了定量化分析，得出了路面老化的主要影响因素，为路面老化的预测提供了理论依据。这些分析的多元回归系数在0.4至0.6之间，而影响因素则是交通量大、总交通量及停车机会（交通灯号、交通挤塞次数）。

Viewing from the record of the road meintenance patrol, the deterioration characteristics of the road pavement have obtained and analyzed for the national highway routes and the urban expressway routes. The fundamental data such as the cracks, corrugation, unevenness, pothole and others were collected for 3-6 years period, and the relating factors such as the traffic volume, road structure, pavement materials, signal density and others were also investigated.Every measures of pavement deterioration has been attempted to build the explanation models using the fundamental factors by the multiple regression analysis or the quantification theory.The multiple regression coefficients of these analyses have been ranging from 0.4 to 0.6, and the influencing factors have been found to be the heavy traffic volume, total traffic volume and the chance of stopping (no. of traffic signal, no. of traffic jams).
