随着我国经济的快速发展和人们生活水平的提高,我国的公路建设将会迎来一个高速发展期,城市道路建设将会有长足的发展。由于沥青砼广泛应用于城市道路,但是随着运行年限加长和交通压力的增长,原有的沥青砼路面开始老化、开裂,影响了城市道路正常功能。通过分析影响城市道路沥青砼路面完整性的自然环境、车辆荷载、沥青砼材料和施工措施等因素,讨论了改善道路沥青砼材料、及时封填裂缝和提高路基的施工质量等沥青砼路面裂缝防治工程措施。
With the rapid economic development in our country and the improvement of people’s living standards, our country’s highway construction will usher in a period of rapid development, and there will be a great development in urban road construction. Asphalt concrete is widely used in urban roads, but with the increase of operating life and traffic pressure, the original asphalt concrete pavement began to age and crack, affecting the normal function of urban roads. By analyzing the natural environment, vehicle load, asphalt concrete material and construction measures which affect the integrity of asphalt pavement in urban roadway, the prevention and cure of asphalt concrete pavement cracks, such as improving road asphalt concrete material, timely sealing cracks and improving the construction quality of roadbed, are discussed Engineering measures.
