摘要
现场热再生技术是指就地加热旧路面,耙松、收集旧料,适当增加新拌的沥青混合料及再生剂进行热搅拌,随后摊铺、碾压、开放交通。现场热再生技术可以创造大量的经济效益及社会效益,并减少对环境的污染。沥青混凝土热再生技术的施工配合比设计是一个至关重要的环节,直接关系着沥青混凝土路面的使用寿命。文章设计了具体工程现场的沥青热再生混合料配合比。
The on-site thermal regeneration technology refers to the progress of local heating of old pavement, raking, collection of old material, add a new appropriate mixture of asphalt and mixture and regenerant, paving, rolling, opening to traffic. The on-site thermal regeneration technology can create a lot of economic benefits and social benefits, and reduce the the environmental pollution. The mix design of thermal regeneration of asphalt is a very important link, directly affecting the lifespan of asphalt concrete pavement. This paper designs a mix proportion of site asphalt thermal regeneration mixture in an engineering.
