Drainage asphalt pavement plant-mixed heat regeneration maintenance method
The invention relates to a drainage asphalt pavement plant-mixed heat regeneration maintenance method. The method comprises steps of 1) recycling waste drainage asphalt mixture; 2) crushing, screeningand storing; 3) mixing and transporting; 4) arranging a waterproof bonding layer; 5) paving and rolling; for the 3), the method comprises specific steps that an old material, regenerant, a new aggregate, new asphalt, mineral powder and fibers are mixed; the plant-mixed hot recycled drainage asphalt mixture is obtained; wherein the plant-mixed hot recycled drainage asphalt mixture comprises 10-50%of an old material, 3-4% of mineral powder and 0.1-0.3% of fibers, the total amount of asphalt and new asphalt contained in the old material is 4-5%, and the mixing amount of the regenerant is controlled to be 2-6% of the amount of asphalt contained in the old material, and the balance is a new aggregate. The method is advantaged in that the high-quality coarse aggregate and a high-viscosity asphalt material of the old drainage asphalt pavement are effectively utilized, and the regenerant, the new aggregate and the new asphalt are reasonably blended, so performance indexes of the recycled mixture and the recycled drainage asphalt pavement can meet technical requirements of the newly-built drainage asphalt pavement.
本发明涉及一种排水沥青路面厂拌热再生养护方法，包括以下步骤：1)废旧排水沥青混合料回收；2)破碎筛分和储存；3)拌和和运输；4)设置防水粘结层；5)摊铺和碾压；步骤3)中，将旧料、再生剂、新集料、新沥青、矿粉和纤维进行拌和，得厂拌热再生排水沥青混合料，厂拌热再生排水沥青混合料中包括10～50％的旧料，3～4％的矿粉，0.1～0.3％的纤维，旧料中含有的沥青与新沥青的总用量为4～5％，再生剂掺量控制在按照旧料中含有的沥青的用量的2～6％，余量为新集料。本发明有效利用旧排水沥青路面优质的粗集料和高黏度沥青材料，合理掺配再生剂、新集料与新沥青，使再生混合料及再生排水沥青路面性能指标均能够达到新建排水沥青路面技术要求。
