| 摘 要： | 温度作用引起的沥青路面开裂是沥青路面使用中的主要病害之一.通过对西南地区高温季节和低温季节的温度场、温度梯度以及路面受力情况进行分析,得出西南地区冬季寒冷季节气温变化对路面的影响仅限于路表,基层及以下土层处于稳定的受压状态;夏季炎热季节气温变化对路面温度影响的幅度较大,温度应力变化幅度也较大的结论.

| Abstract: | The cracking of the asphalt pavement caused by temperature is one of the main diseases.Through the analysis of temperature field,temperature gradient and stress of the road in high-temperature and low-temperature in Southwest Region,it is concluded that the impact of temperature in cold winter season in Southwest is only limited to the surface of road,and the base and the sub-base are in a stable state of compression,and that the temperature changes in hot summer season have a great impact on the rate of ro... |
