The invention discloses a high-performance low-temperature asphalt pavement maintenance seal coat, and belongs to the technical field of pavements. The high-performance low-temperature asphalt pavement maintenance seal coat comprises a wear-resistant maintenance seal coat and a self-repairing slurry seal coat, wherein the wear-resistant maintenance seal coat comprises the following components: 7-11% of modified refined asphalt, 6-8% of water, 80-85% of an aggregate, 1-3% of filler, and 1-1.5% of a wear-resistant agent; and the self-repairing slurry seal coat comprises a fine seal coat, a middle seal coat and a coarse seal coat. According to the invention, the prepared wear-resistant maintenance seal coat is laid on the upper surface of the self-repairing slurry seal coat, different aggregates are formed by different proportions of the coarse aggregate, the middle aggregate, the fine aggregate and mineral powder, and a wear-resistant agent is added into the protective seal coat, so thatthe wear resistance is improved. The prepared fine seal coat is laid on the surface of the asphalt pavement, the middle seal coat is evenly laid on the upper surface of the fine seal coat, the coarseseal coat is evenly laid on the upper surface of the middle seal coat, the three coats are laid to form the self-repairing slurry seal coat, and the self-repairing effect is improved.
本发明公开了一种高性能低温沥青路面养护封层，属于路面技术领域，包括耐磨养护封层和自修复稀浆封层，所述耐磨养护封层成分包括：改性炼化沥青，水，集料，填料和耐磨剂，其配比为：改性炼化沥青7‑11％,水6‑8％，集料80‑85％，填料1‑3％，耐磨剂1‑1.5％；所述自修复稀浆封层分为括：细封层、中封层、粗封层，本发明在自修复稀浆封层的上表面铺设一层制备好的耐磨养护封层，通过粗集料，中集料、细集料和矿粉不同配比组成不同集料，护封层中添加耐磨剂，提高耐磨性；本发明将制备好的细封层铺设在沥青路面的表面，将中封层均匀铺设在细封层上表面，将粗封层均匀铺设在中封层上表面，三层铺设形成一层自修复稀浆封层，提高自修复效果。
