摘要
沥青混凝土路面发生病害的原因,主要是由于路基土的承载力,大型汽车的交通量及路面结构三者失去平衡而造成的。为了提高沥青混凝土路面的质量,使其胜任交通荷载、气候条件等复杂因素的作用,目前可以从两个方面着手:对于现有路面,则要设法消除病害,加强养护维修,以保持其使用功能;对于新铺路面,则要从路面结构、路面材料、施工工艺等方面研究改进,以提高沥青混凝土路面行驶条件,保证质量、延长使用寿命。
The imbalance of bearing capacity of roadbed loess, quantity traffic of large-scale vehicles and the pavement structure are the reasons for asphalt concrete pavement disease. We could do from two ways to improve the quality of asphalt concrete pavement for the traffie load and climate change. For existing pavement, we should try to eliminate disease and strengthen maintenance work to secure its function; for scheduled pavement, pavement structure, pavement material, construction process should be improved to improve traveling condition of asphalt concrete pavement and prolong its service life.
