Cracking-reducing foamed asphalt pavement recycled material and preparation and construction method thereof
The invention relates to the technical field of road engineering, and discloses a cracking-reducing foamed asphalt pavement recycled material and a preparation and construction method thereof, the recycled material is composed of the following raw materials: an old asphalt pavement recycled material, mineral powder, foamed asphalt, fine aggregate, water, cement, a foaming agent and fiber; the raw materials of the foamed asphalt cold recycled material are reasonably matched, so that a road has good water stability and rutting resistance, and meanwhile, the tensile strength and shear strength of the foamed asphalt mixture are improved, so that the shrinkage rate of the foamed asphalt mixture is reduced, and cracking is reduced; meanwhile, by adding the foaming agent into the foamed asphalt mixture, the foaming performance of matrix asphalt can be improved, the expansion rate can be increased, and the half-life period can be prolonged, so that the bonding performance of the foamed asphalt and the aggregate is improved, the aggregate is prevented from loosening and threshing, the quality of the foamed asphalt pavement regenerated material is ensured, and the mechanical property is improved; therefore, pavement cracking is reduced, and the service life of the pavement is prolonged.
本发明涉及道路工程技术领域，本发明公开了一种减少开裂泡沫沥青路面再生材料及制备和施工方法，该再生材料由以下原料组成：旧沥青路面回收材料、矿粉、泡沫沥青、细集料、水、水泥，发泡剂以及纤维；本发明的泡沫沥青冷再生材料的原料合理配伍，使道路具有良好的水稳定性以及抗车辙性能，同时提高了该泡沫沥青混合料的抗拉强度和抗剪强度，从而降低其收缩率，减少开裂；同时在泡沫沥青混合料中加入发泡剂可以提高基质沥青的发泡性能，提高膨胀率，延长半衰期，从而提高泡沫沥青与集料的粘结性能，避免集料松散脱粒，保证了泡沫沥青路面再生材料的质量和提高其力学性能，并协同合理的施工方法，从而减少路面开裂，提高路面的使用寿命。
