采用传统的施工工艺对公路进行养护,不仅增加了废料外运成本,还会因为处理不当而造成环境污染。而采用废旧沥青路面材料再生技术,不仅可以避免废弃材料堆放对土地的占用和对环境的污染,还可以减少对石料、沥青、水泥的需求,降低筑养路成本。就地冷再生作为一种较为成熟的绿色公路维修改造技术,具有简化施工工艺、节约材料、缩短工期和降低成本等多个优势,已经广泛应用于国内多种道路的维修改造中。目前,国内市场上就地冷再生机(以下简称冷再生机)品牌众多,既有国外知名品牌维特根、宝马 The traditional construction technology for road maintenance, not only increased the cost of waste outbound, but also because of improper handling and environmental pollution. The use of waste asphalt pavement material regeneration technology, not only to avoid waste landfill on the occupation of land and environmental pollution, but also can reduce the demand for stone, asphalt, cement, reduce the cost of road construction. Cold regeneration in situ as a more mature green highway maintenance and modification technology, with a number of advantages such as simplifying the construction process, saving materials, shortening the construction period and reducing costs, has been widely used in the maintenance of a variety of domestic roads. At present, the local market cold regenerative machine (hereinafter referred to as cold regeneration machine) many brands, both well-known foreign brands Wirtgen, BMW
