提高新铺沥青路面质量与治理大量旧沥青路面上的裂缝病害,成为当务之急。实际上,防治沥青路面的裂缝,也就是当前改善沥青路面使用质量的关键。本文即在近年来有关裂缝研究工作的基础上,从改善沥青性能的途径出发,并在沥青混合料与路面结构层上着手,按照提高经济效益的原则,着重研究了防治沥青路面裂缝的途径与方法。 Improve the quality of new paved asphalt pavement and control a large number of cracks in the old asphalt pavement, become a top priority. In fact, the prevention of cracks in asphalt pavement, which is the key to improving the quality of asphalt pavement. Based on the research work on cracks in recent years, this paper starts from the ways to improve the performance of asphalt, and on the asphalt mixture and pavement structure layer, in accordance with the principle of improving economic efficiency, focuses on ways to prevent and control asphalt pavement cracks method.
