Foamed asphalt cold recycling construction method of pavement
The invention relates to the technical field of pavement construction, in particular to a foamed asphalt cold recycling construction method of a pavement, which solves the defect of low recovery rateof old asphalt materials in the prior art, and comprises the following steps: S1, carrying out road closure; S2, cleaning a road surface, putting construction equipment in place, and measuring a roadsurface; S3, milling the original pavement to a base layer surface, recycling the old asphalt material, and performing lower bearing layer cleaning, deflection detection and disease treatment; S4, treating the old asphalt material, and performing crushing; S5, mixing the foamed asphalt, the old asphalt particles and an additive to obtain a recycled asphalt mixture; S6, paving the recycled asphaltmixture, and performing initial pressing, re-pressing and final pressing to finish construction. According to the invention, the old asphalt material is crushed, and additives such as foamed asphalt,aggregate, filler and the like are added into the old asphalt material particles, so that the cohesiveness and stability of asphalt can be improved, the method is suitable for cold regeneration, and the recovery rate of the old asphalt material is improved.
本发明涉及路面施工技术领域，尤其涉及一种路面的泡沫沥青冷再生施工工法，解决现有技术中存在的沥青旧料回收率低的缺点，包括以下步骤：S1、封闭交通；S2、路表清洁、施工设备就位、路面测量；S3、将原路面铣刨至基层面，回收沥青旧料，进行清理下承层、弯沉检测、病害处理；S4、处理沥青旧料，粉碎；S5、将泡沫沥青、沥青旧料颗粒与添加剂拌和，得再生沥青混合料；S6、摊铺再生沥青混合料，经初压、复压和终压，施工完成。本发明将沥青旧料粉碎，并在沥青旧料颗粒中添加了泡沫沥青、集料、填充料等添加剂，可提高沥青的粘聚性和稳定性，适用于冷再生，提高沥青旧料的回收率。
