Abstract

In order to explore the cause of early damage of highway asphalt pavement in Baiyin area of Gansu Province, this paper analyzed the main factors that affected the performance of asphalt pavement and investigated the use of asphalt pavement in this area, climate environment, and traffic conditions. By taking Baiyin section of National Highway 109 as an example, the specific data were deeply analyzed. Based on the investigation of pavement use, the situation and decay rule of local asphalt pavement were summarized. According to the investigation of the climate environment, the influence of solar radiation, temperature difference, and other conditions on the performance of local asphalt pavement was analyzed. Based on the investigation of traffic conditions, the influence of the proportion of oversized trucks and traffic load grade on the performance of local asphalt pavement was clarified. The results show that the natural climate environment, traffic load grade, the thickness of pavement surfaces, and the rationality of maintenance method are the main reasons that affect the early damage of the pavement.
