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

从道路养护巡查记录中，得出并分析了国道和城市快速路道路路面的劣化特征。收集了3 ~ 6年的裂缝、波纹、不平、坑洼等基础数据，并对交通量、道路结构、路面材料、信号密度等相关因素进行了调查。通过多元回归分析或量化理论，试图利用基本因素建立路面劣化的解释模型。这些分析的多元回归系数在0.4 ~ 0.6之间，发现影响交通流量的因素是交通繁忙量、总交通量和停车机会(no。交通信号，没有。交通堵塞)。

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).
