市政道路工程沥青路面裂缝控制研究

Research on Crack Control of Asphalt Pavement in Municipal Road Project

近年来,随着我国经济的发展,我国市政工程建设日趋完善。目前,我国市政道路的施工技术和机械化水平不断提高,进一步加强了沥青施工质量。但是,在具体的施工过程中,受自然环境、温度、施工工艺等因素的影响,很容易导致沥青裂缝的发生。为了有效地提高市政道路工程的整体质量,有必要深入分析沥青裂缝产生的原因和预防措施,加强后续的养护和管理。结合我国市政道路混凝土路面裂缝,探讨了路面裂缝的机理和分布特征以及不同类型裂缝的防治,并提出了一些防治技术,为了提高沥青施工质量,延长城市沥青的使用寿命。

In recent years,with the development of China’s economy,the construction of municipal project in China is becoming perfect.At present,the construction technology and mechanization level of municipal roads in China have been continuously improved,which has further strengthened the quality of asphalt construction.However,in the specific construction process,affected by the natural environment,temperature,construction technology and other factors,it is easy to lead to the occurrence of asphalt cracks.In order to effectively improve the overall quality of municipal road project,it is necessary to deeply analyze the causes and preventive measures of asphalt cracks,and strengthen subsequent maintenance and management.Combined with the cracks of concrete pavement of municipal roads in China,the mechanism and distribution characteristics of pavement cracks and the prevention of different types of cracks are discussed,and some prevention techniques are put forward,in order to improve the quality of asphalt construction and prolong the service life of urban asphalt.
