沥青路面裂缝成因与防治策略探析

Analysis of Causes and Prevention Strategies for Asphalt Pavement Cracks

旨在对沥青路面裂缝的成因和防治策略进行分析。沥青路面裂缝的主要成因包括温度变化、车辆负荷、沥青自身性质等因素。针对不同的成因可以采取不同的防治策略,对于温度变化引起的裂缝可使用表层封闭处理;对于车辆负荷引起的裂缝可配置弹性防护层;对于沥青自身性质引起的裂缝可添加聚合物、橡胶等改性剂。采取有效的防治策略可以延长路面的使用寿命,减少裂缝的发生,提高道路的质量和安全性。经过实际案例验证,合理的维护措施可以显著降低沥青路面裂缝的发生率。

Aiming to analyze the causes and prevention strategies of asphalt pavement cracks.The main causes of asphalt pavement cracks include temperature changes,vehicle loads,and the properties of the asphalt itself.Different prevention and control strategies can be adopted for different causes,and surface sealing treatment can be used for cracks caused by temperature changes;Elastic protective layers can be configured for cracks caused by vehicle loads;Polymer,rubber and other modifiers can be added to cracks caused by the properties of asphalt itself.Adopting effective prevention and control strategies can prolong the service life of the road surface,reduce the occurrence of cracks,and improve the quality and safety of the road.Through practical case verification,reasonable maintenance measures can significantly reduce the occurrence rate of asphalt pavement cracks.
