Permeable asphalt mixture and preparation method thereof
The invention relates to the field of pavement asphalt materials, and particularly discloses a permeable asphalt mixture and a preparation method thereof. The invention relates to a permeable asphalt mixture, which is prepared from the following raw materials in parts by weight: 4.3 to 6 parts of asphalt, 78 to 90 parts of recycled coarse aggregate, 19 to 31 parts of recycled fine aggregate, 3 to 5 parts of mineral powder, 0.1 to 0.3 part of reinforced fiber and 0.516 to 0.72 part of high-viscosity modifier, the recycled coarse aggregate is obtained by crushing, acidifying and carbonizing waste concrete. The permeable asphalt mixture can be used for permeable pavements, and has the advantages of good water permeability, good water damage resistance, high strength, large bearing capacity and good high temperature resistance.
本申请涉及路面沥青材料领域，具体公开了一种透水沥青混合料及其制备方法。一种透水沥青混合料，以重量份数计，包括如下原料：沥青4.3‑6份、再生粗骨料78‑90份、再生细骨料19‑31份、矿粉3‑5份、增强纤维0.1‑0.3份以及高粘改性剂0.516‑0.72份；所述再生粗骨料由废旧混凝土经过破碎、酸化以及碳化处理得到。本申请的透水沥青混合料可用于透水路面，其具有透水性好、抗水损害性能好、强度高、承载能力大以及耐高温性能好的优点。
