High-performance drainage asphalt mixture and method for paving drainage pavement by using same
The invention discloses a high-performance drainage asphalt mixture which is formed by paving an asphalt mixture, the asphalt mixture comprises high-viscosity modified asphalt, graded aggregate and wood fiber, and the doping proportion of the high-viscosity modified asphalt is 5.0-5.6% of the total mass of the asphalt mixture; the doping proportion of the wood fibers is 0.3% of the total mass of the asphalt mixture; the graded aggregate comprises 10-15mm coarse aggregate, 5-10mm coarse aggregate, 0-3mm fine aggregate, mineral powder and cement, the ratio of the 10-15mm coarse aggregate to the 5-10mm coarse aggregate to the 0-3mm fine aggregate to the mineral powder to the cement is (43-47): 37: (13-17): 1.5: 1.5, and the PAC-13 asphalt mixture is prepared by designing the ratio and mixing. The drainage asphalt pavement paved by the PAC-13 asphalt mixture has better water damage resistance, rut resistance and dispersion resistance.
本发明公开了高性能排水沥青混合料，由沥青混合料摊铺构成，所述沥青混合料包括有高黏改性沥青、级配集料和木质纤维，所述高黏改性沥青掺加比例为沥青混合料总质量的5.0‑5.6%；所述木质纤维掺加比例为沥青混合料总质量的0.3%；所述级配集料包括有10‑15mm粗集料、5‑10mm粗集料、0‑3mm细集料、矿粉和水泥，其中10‑15mm粗集料：5‑10mm粗集料：0‑3mm细集料：矿粉：水泥的配比为43‑47：37：13‑17：1.5：1.5，配比设计并拌合制备获得PAC‑13沥青混合料，通过PAC‑13沥青混合料摊铺的排水沥青路面抗水损害能力、抗车辙能力及抗分散能力较好。
