沥青混凝土路面裂缝产生的原因及预防措施

随着城市化进程的加快,城市主干道及快速路的大量修建,半刚性类材料以其优良的工程性能和显著的经济效益在市政建设中得到了广泛的应用,并在道路建设中占有越来越重要的地位。然而,半刚性材料的缺点在于抗变形能力低,在温度、湿度变化时易产生裂缝,当沥青面层较薄时易形成反射裂缝,沥青路面本身也易产生低温裂缝,沥青路面一旦出现裂缝,有可能导致路面结构性破坏,影响路面的使用功能。

The Causes and Preventive Measures of Cracks in Asphaltic Concrete Pavement

With the accelerated urbanization process,urban trunk roads and a large number of expressways are constructed,semi-rigid type material has been widely used in municipal building for its excellent work performance and significant economic benefits and has a special and more important position in road construction.However,the shortcomings of semi-rigid material are low deformation resistance,the temperature and humidity changes,easy to crack,when the asphalt surface is thin,it is easy to form reflective cracking,asphalt pavement itself is easy to produce low-temperature cracks.The cracks in asphalt pavement may lead to structural damage roads which affects the use of road.
