旧沥青混合料再生技术目前已成为国际上道路维修改造的主要方法之一。以就地热再生技术为研究对象,对旧料性能评价、再生沥青混合料配合比设计、生产工艺等关键技术进行了研究。通过室内试验,结合实际工程,表明再生沥青混合料具有良好的路用性能,经济效益和社会效益十分明显。 Old asphalt mixture regeneration technology has now become one of the main ways of repairing and repairing roads in the world. Taking the on-site thermal regeneration technology as the research object, the key technologies such as the evaluation of the old material performance, the mix design of the recycled asphalt mixture and the production technology were studied. Through laboratory tests, combined with the actual project shows that recycled asphalt mixture has good road performance, economic and social benefits are obvious.
