为了减小沥青混凝土路面的病害程度,国内外都采取了不同的工程措施,如合理的设计、控制施工的质量等等。但沥青混凝土的病害问题依旧十分突出,城市公路同高速公路一样面临实际的重载化和超载的现象,而面层的剪应力、基层和底基层底部的拉应力和路基顶部的压应力都随轴载的增加而增加,超载对沥青路面的早期破坏影响非常严重。另外路面的开裂也是很普遍的一种病害现象,国内外就此采取过许多方法进行防治,但仍然严重影响着车辆运行的安全性、舒适性。日益增长的经济建设对公路交通提出了越来越高的要求,围绕减少公路病害,提高公路寿命的研究为世界各国所重视。现主要分析土工格栅在沥青混凝土路面中的应用。
In order to reduce the degree of disease of asphalt concrete pavement, different engineering measures have been taken both at home and abroad, such as reasonable design, quality control of construction and so on. However, the disease of asphalt concrete is still very outstanding. Urban highway is faced with the same phenomenon of overload and overloading as the highway. The shear stress of the surface layer, the tensile stress at the bottom and the top of the subgrade Axle load increases and increases, overloading on asphalt pavement early damage is very serious. In addition, cracking of the pavement is also a common disease phenomenon. Many methods both at home and abroad have been adopted to prevent and cure this problem. However, the safety and comfort of the vehicles are still seriously affected. The ever-increasing economic construction has put forward higher and higher requirements on the road traffic. The research on reducing road diseases and increasing the life of the road is valued by all countries in the world. Now mainly analyzes the application of geogrid in asphalt concrete pavement.
