寒冷地区公路由于季节温度变化等因素造成路面结构出现裂缝、坑槽等破坏,直接影响到了公路的使用质量,本文根据松原大广至深井子公路实际使用情况,发现实际应用中路面病害的形成和水泥稳定砂砾路面结构性能有着非常重要的关系。如何改善和提高寒冷地区路面结构的使用性能,成为提高寒冷地区路面结构使用耐久性的一个重要因素。本文通过对该路段的调查和分析,提出了提高水泥稳定砂砾基层使用性能的解决措施。 In the cold area, due to seasonal temperature changes and other factors, the pavement structure cracks and pits and other damage directly affect the quality of use of the highway. Based on the actual use of the road between the Songyuan Daguang and Shamjing sub-roads, Cement stabilized gravel pavement structural performance has a very important relationship. How to improve and enhance the serviceability of the pavement structure in cold areas has become an important factor to improve the durability of the pavement structure in cold areas. Based on the investigation and analysis of the road section, this paper puts forward some measures to improve the performance of cement stabilized gravel base.
