Emulsified asphalt pavement recycled material capable of reducing cracking as well as preparation and construction methods thereof
The invention provides an emulsified asphalt pavement recycled material capable of reducing cracking as well as preparation and construction methods thereof, and relates to the technical field of highway and municipal engineering. The strength of the recycled material can be improved, the shrinkage cracking rate of the recycled material can be reduced, and therefore, the overall bearing capacity of a pavement can be improved, and the service life of the pavement can be prolonged. The recycled material comprises the following components in parts by mass: 70-85 parts of an asphalt pavement recycled material, 15-29 parts of gravels, 1.0-1.5 parts of an old asphalt activator, 3.5-5.0 parts of emulsified asphalt, 1-2 parts of slag sulphoaluminate and/or ferro-aluminate cement and 0.1-1.0 part of fibers. The emulsified asphalt comprises the following components in parts by mass: 62-70 parts of matrix asphalt, 2-4 parts of an emulsifier and 30-38 parts of water. The cement comprises the following components in parts by mass: 75-90 parts of granulated blast furnace slag, 3-5 parts of sulfur or iron aluminate cement clinker and 3-15 parts of gypsum. The technical scheme provided by the invention is suitable for the processes of material preparation and road paving.
本发明提供了一种减少开裂乳化沥青路面再生材料及制备和施工方法，涉及公路和市政工程技术领域，能够提高再生材料的强度和降低其收缩开裂率，从而提高路面的整体承载能力和路面的使用寿命；该再生材料按质量份包括：沥青路面回收材料70‑85份、碎石15‑29份、旧沥青活化剂1.0‑1.5份、乳化沥青3.5‑5.0份、矿渣硫铝酸盐和/或铁铝酸盐水泥1‑2份以及纤维0.1‑1.0份；乳化沥青按质量份包括：基质沥青62‑70份、乳化剂2‑4份以及水30‑38份；水泥按质量份包括：粒化高炉矿渣75‑90份、硫或铁铝酸盐水泥熟料3‑5份、石膏3‑15份。本发明提供的技术方案适用于材料制备和公路铺筑的过程中。
