High-performance ultrathin asphalt wearing layer and paving method thereof
The invention relates to the technical field of pavement construction, in particular to a high-performance ultra-thin asphalt wearing layer and a paving method thereof.The ultra-thin asphalt wearing layer comprises a waterproof bonding layer arranged on an original pavement and a surface wearing layer arranged on the waterproof bonding layer; the surface wearing layer is prepared from the following components in parts by weight: 84-90 parts of aggregate, 5-8 parts of modified asphalt, 3-8 parts of mineral powder and 0.1-0.5 part of polyester fiber; the ultra-thin asphalt wearing layer provided by the invention is used for pavement maintenance, and due to the adoption of the special binding material, the pavement has ultra-strong interlayer bonding performance, anti-aging performance, reflection crack resistance and low-temperature cracking resistance, and also has good construction workability, so that the wearing layer has thinner structural thickness.
本发明涉及路面施工技术领域，特别涉及一种高性能超薄沥青磨耗层及其铺装方法，所述超薄沥青磨耗层包括设置在原路面上的防水粘结层和设置在所述防水粘结层上方的表面磨耗层；所述表面磨耗层包括以下重量份的组分制备而成：集料84‑90份、改性沥青5‑8份、矿粉3‑8份、聚酯纤维0.1‑0.5份；通过本发明提供的超薄沥青磨耗层用于路面养护，由于采用了特殊的粘结料，使得路面具有超强的层间结合性能、抗老化性能、抗反射裂缝性能、抗低温开裂性能的同时，还具有良好的施工和易性，使得该磨耗层具有更薄的结构厚度。
