Cold-mixed permeable asphalt and preparation method thereof
The invention relates to the field of asphalt materials, and particularly discloses cold-mixed permeable asphalt and a preparation method thereof. The cold-mixed permeable asphalt is prepared from the following raw materials in parts by weight: 20-30 parts of single-component polyurethane, 10-20 parts of asphalt, 50-60 parts of aggregate, 1-3 parts of porous ceramic microbeads, 1-3 parts of an alkali activator, 3-5 parts of reinforced fibers and 3-5 parts of a 4A molecular sieve, the aggregate comprises the following raw materials in parts by weight: 13-16 parts of coarse aggregate with the particle size of 12-19mm, 20-30 parts of coarse aggregate with the particle size of 8-11mm, 10-13 parts of fine aggregate with the particle size of 1-4.5 mm and 1-3 parts of mineral powder. The cold-mixed permeable asphalt disclosed by the invention has relatively good water permeability under the synergistic effect of all the components, and the deformation phenomenon is reduced.
本申请涉及沥青材料领域，具体公开了一种冷拌透水沥青及其制备方法。一种冷拌透水沥青，包括以下重量份的原料：单组分聚氨酯20‑30份，沥青10‑20份，集料50‑60份，多孔陶瓷微珠1‑3份，碱激发剂1‑3份，增强纤维3‑5份，4A分子筛3‑5份；所述集料包括以下重量份的原料：粒度为12‑19mm的粗集料13‑16份，粒度为8‑11mm的粗集料20‑30份，粒度为1‑4.5mm的细集料10‑13份，矿粉1‑3份。本申请的冷拌透水沥青，在各个组分的协同作用下，具有较好的透水性能，减少了变形的现象。
