UAW ultrathin wearing layer asphalt mixture and construction method thereof
The invention relates to the technical field of pavement construction, and particularly discloses a UAW ultrathin wearing layer asphalt mixture and a construction method thereof. The UAW ultrathin wearing layer asphalt mixture is prepared from the following raw materials in parts by weight: 20 to 30 parts of aggregate, 30 to 40 parts of matrix asphalt, 10 to 20 parts of SBS (Styrene Butadiene Styrene) modified emulsified asphalt, 3 to 5 parts of mineral powder, 5 to 8 parts of cement, 5 to 8 parts of wear-resistant filler and 0.3 to 0.5 part of mixed fiber, the aggregate is coarse aggregate with the particle size of 5-9 mm and fine aggregate with the particle size of 1-3 mm, and the mixed fiber is at least one of glass fiber, basalt fiber and polyester fiber. According to the UAW ultra-thin wearing layer asphalt mixture, the bonding strength, elasticity and toughness of the asphalt mixture are improved through the SBS modified emulsified asphalt, the phenomena of peeling and cracking of the asphalt mixture are reduced, pores of the ultra-thin wearing layer are filled with the wear-resistant filler and the mixed fibers, the compactness of the ultra-thin wearing layer is improved, and then the strength and durability of the asphalt mixture are improved.
本申请涉及路面施工技术领域，具体公开了一种UAW超薄磨耗层沥青混合料及其施工方法。一种UAW超薄磨耗层沥青混合料，包括以下重量份的原料：集料20‑30份，基质沥青30‑40份，SBS改性乳化沥青10‑20份，矿粉3‑5份，水泥5‑8份，耐磨填料5‑8份，混合纤维0.3‑0.5份；所述集料为粒径为5‑9mm的粗集料和粒径为1‑3mm的细集料，所述混合纤维为玻璃纤维、玄武岩纤维和聚酯纤维中的至少一种。本申请的UAW超薄磨耗层沥青混合料，通过SBS改性乳化沥青提高沥青混合料的粘结强度和弹韧性，减少沥青混合料脱皮、开裂现象，通过耐磨填料和混合纤维填充超薄磨耗层的孔隙，提高超薄磨耗层的密实度，进而提高沥青混合料的强度和耐久性。
