旧沥青路面再生施工种类沥青路面的再生按其施工工艺的不同,可以分为厂拌热再生、厂拌冷再生、就地热再生、就地冷再生四种方式。各种类的施工方法和优缺点厂拌热再生将旧沥青路面用普通铣刨机铣刨后运回搅拌厂储存备用,通过集中破碎、筛分(必要时),并分析旧料中沥青含量、沥青老化程度、碎石级配等指标,根据高等级公路路面不同层次的质量要求,进行配合比设计,确定旧沥青混合料的添加比例,掺入一定数量的新集料、沥青和再生剂(必要时)进行拌和,成为达到规范规定的各项指标的新混合料,从而获得优良的再生沥青混凝土,最后按照与新建沥青路面完全相同的方法重新铺筑。这种再生方式能有效地用于各种 Regeneration of old asphalt pavement types of asphalt pavement regeneration according to their different construction techniques can be divided into hot mix plant regeneration, plant cold regeneration, on-site thermal regeneration, cold regeneration in four ways. Various types of construction methods and advantages and disadvantages Plant hot mix regeneration After the old asphalt pavement with ordinary milling machine milling back transported to the mixing plant for storage, through the focus on crushing, screening (if necessary), and analysis of the old asphalt content , The degree of aging of asphalt and the gradation of gravel, etc. According to the quality requirements of different levels of high-grade highway pavement, the proportioning design is adopted to determine the proportion of old asphalt mixture added with a certain amount of new aggregate, asphalt and regenerant (If necessary) to a new mixture of all the indicators that meet the specifications, resulting in excellent recycled asphalt concrete and finally being resurfaced in exactly the same way as the new asphalt pavement. This type of regeneration can be effectively used for various purposes
