Environment-friendly asphalt mixture and preparation method thereof
The invention relates to the technical field of preparation of asphalt mixtures, and particularly discloses an environment-friendly asphalt mixture and a preparation method thereof. The environment-friendly asphalt mixture is prepared from the following components in parts by weight: 2000 to 2500 parts of fine aggregate, 2000 to 2500 parts of coarse aggregate, 150 to 200 parts of mineral powder, 250 to 300 parts of asphalt, 50 to 80 parts of resin powder, 50 to 100 parts of an emulsifier, 0.6 to 1.2 parts of an anti-stripping agent, and 2000 to 2500 parts of modified recycled aggregate, wherein the modified recycled aggregate is prepared from waste concrete blocks through crushing, acid pickling, alkalization, modification, calcination and other procedures. According to the environment-friendly asphalt mixture disclosed by the invention, the waste concrete blocks are recycled, and multiple modification procedures are matched for treatment, so the environment-friendly asphalt mixture has the advantages of environmental protection, energy conservation, and high Marshall stability and immersion residue stability at the same time.
本申请涉及沥青混合料制备技术领域，具体公开了一种环保型沥青混合料及其制备方法。一种环保型沥青混合料，由以下重量份数的组分组成：细骨料2000‑2500份；粗骨料2000‑2500份；矿粉150‑200份；沥青250‑300份；树脂粉末50‑80份；乳化剂50‑100份；抗剥落剂0.6‑1.2份；改性再生骨料2000‑2500份；所述改性再生骨料由废弃混凝土块经粉碎、酸洗、碱化、改性、煅烧等工艺处理制得。本申请的环保型沥青混合料通过对废弃混凝土块进行回收利用，再配合多重改性工艺处理，使其同时具有环保节能，马歇尔稳定度和浸水残留稳定度高的优点。
