Crack pouring material for pavement crack non-inductive traceless repair and application method thereof
The invention discloses a crack pouring material for pavement crack non-inductive traceless repair and an application method thereof, and the crack pouring material comprises three parts, namely a polyurethane elastomer, a graded broken stone mixture and a spraying material, wherein the polyurethane elastomer is prepared from the following raw materials in parts by weight: 10 to 40 parts of polyether polyol, 5 to 10 parts of a bonding reinforcing agent, 40 to 60 parts of a polyurethane prepolymer, 20 to 30 parts of a toughening diluent, 0.5 to 2 parts of a catalyst, 2 to 5 parts of a coloring agent and 0.5 to 1 part of a de-foaming agent; a cementing material used by the graded broken stone mixture is a polyurethane elastomer, stone grading is the same as that of an original pavement, and the asphalt-aggregate ratio is 8-12%. According to the crack pouring material, the water sealing and leaking stoppage effect and durability on cracks are greatly improved, the gravel mixture which is the same as an original pavement in grading type, high in asphalt-aggregate ratio and small in particle size is poured in the middle, the structural similarity of a repaired position and the original pavement can be greatly improved, the color of the polyurethane elastomer is adjusted according to field working conditions, and the polyurethane elastomer is matched with low-mesh filler to be sprayed on the surfaces of the cracks; the similarity with the original pavement is improved, and non-inductive and traceless crack repair is realized.
本发明公开了一种路面裂缝无感无痕修复用的灌缝材料及其应用方法，包括灌缝材料包括聚氨酯弹性体、级配碎石混合料及喷涂材料三部分，其中聚氨酯弹性体包括以下重量份数的原料：聚醚多元醇10‑40份、粘接补强剂5‑10份、聚氨酯预聚体40‑60份、增韧稀释剂20‑30份、催化剂0.5‑2份、着色剂2‑5份、消泡剂0.5‑1份；级配碎石混合料所用胶结料为聚氨酯弹性体，石料级配与原路面同类型，油石比8‑12％。本发明的灌缝材料其大幅提升对裂缝的封水堵漏效果及耐久性，中间灌注与原路面同级配类型、高油石比、小粒径碎石混合料可，大幅提升修复处与原路面构造相似度，聚氨酯弹性体颜色根据现场工况调节，配合低目数填料，喷涂于裂缝表面，提升与原路面相似度，实现裂缝无感无痕修复。
