Energy-saving recycled asphalt mixture and preparation method thereof
The invention relates to an energy-saving recycled asphalt mixture and a preparation method thereof. The recycled asphalt mixture is prepared from the following raw materials in parts by weight: 3-7 parts of new asphalt, 58.2-135.8 parts of stone, 30-70 parts of an old asphalt mixture, 1.8-4.2 parts of mineral powder, 0.29-0.67 part of basalt fibers, 0.29-0.67 part of polyester fibers, 0.06-0.14 part of polyethylene wax, 0.195-0.455 part of a warm mixing agent and 1.95-4.55 part of a regenerant. The preparation method of the recycled asphalt mixture comprises the following steps: mixing all the raw materials at the temperature of 140-160 DEG C, stirring for 15-20 minutes at the rotating speed of 300-500 r/min, and uniformly mixing to obtain the energy-saving recycled asphalt mixture. The recycled asphalt mixture disclosed by the invention uses a large amount of old asphalt mixture, so that resource recycling is realized to a large extent, resources are saved, meanwhile, the high pavement performance is kept, the viscosity is low, the temperature during mixing and forming is reduced by 35 DEG C or above, emission of harmful gas such as greenhouse gas and asphalt smoke is reduced, energy conservation and environmental protection are achieved, and the production and construction operation environment is greatly improved.
本申请涉及一种节能型再生沥青混合料及其制备方法，再生沥青混合料所用原料包括以下重量份的组分：新沥青3~7份、石料58.2~135.8份、旧沥青混合料30~70份、矿粉1.8~4.2份、玄武岩纤维0.29~0.67份、聚酯纤维0.29~0.67份、聚乙烯蜡0.06~0.14份、温拌剂0.195~0.455份、再生剂1.95~4.55份；再生沥青混合料的制备方法为：在140~160℃的温度下，将所有所述原料混合，在300~500r/min的转速下，搅拌15~20min，混合均匀，得到节能型再生沥青混合料，本申请的再生沥青混合料使用较大量的旧沥青混合料，较大限度的实现了资源回收再生利用，节约资源，同时保持了较高的路用性能，且黏度较低，将拌和、成型时的温度降低35℃以上，减少了温室气体、沥青烟等有害气体的排放，节能环保，大大改善了生产和施工作业环境。
