试论沥青路面材料的再生工艺及专用机械设备的发展

沥青混凝土路面是目前国内外道路交通的主要面层结构,而沥青材料的热溶解特性,使沥青混合料能够较为容易地实现再生利用。作为节能减排和固废利用的重要组成部分,沥青混合料再生利用的工程规模及其技术进步也反映了一个国家或地区国民经济的发展和技术进步的总体水平。注重并优化沥青混凝土路面材料的再生工艺,并以符合技术条件的专用设备完成作业是路面材料高质量再生利用的前提和必要条件。

On the Recycling Process of Asphalt Pavement Materials and the Development of Special Machinery

Asphalt concrete pavement is the main surface structure of road traffic at home and abroad,and the thermal dissolution characteristics of asphalt materials make it easier for asphalt mixtures to be recycled. As an important part of energy saving,emission reduction and solid waste utilization,the engineering scale and technological progress of asphalt mixture recycling also reflects the overall level of national economic development and technological progress in a country or region.Paying attention to and optimizing the regeneration process of asphalt concrete pavement materials,and completing the operations with special equipment that meets technical conditions are the prerequisites and necessary conditions for high-quality pavement material recycling.
