高原高寒地区公路沥青混凝土的耐久性与性能优化分析

Durability and Performance Optimization Analysis of Highway Asphalt Concrete in Plateau and Cold Region

文中结合高原高寒地区公路项目施工实践,对低温、昼夜温差大以及紫外线辐射对沥青混凝土耐久性的影响进行分析,并从材料选择、配合比设计和施工工艺三个方面,提出优化建议。通过路面质量调查、使用情况监测和材料性能检测,相关人员对耐久性优化效果进行评估。结果表明,采取合理的优化措施,可显著提高高原高寒地区沥青混凝土的耐久性。

In order to study the durability of asphalt concrete for highway in the high cold region of the plateau,combined with the construction practice of a highway project in the high cold region of the plateau,the paper analyzes the effects of low temperature,large temperature difference between day and night and ultraviolet radiation on the durability of asphalt concrete,and puts forward performance optimization suggestions from three aspects:material selection,mix design and construction technology.The results of durability optimization were evaluated through pavement quality investigation,actual use monitoring and material performance testing.The results show that the durability of asphalt concrete can be significantly improved by reasonable optimization measures.
