Material for repairing pits in asphalt pavement and preparation method of material
The invention relates to a repairing material for asphalt pavement pits. The repairing material comprises a macroporous matrix mixture and a high-performance cement-based grouting material, wherein the macroporous matrix mixture is prepared from the following raw materials in parts by mass: 15 to 20 parts of 4.75 to 9.5 mm aggregate; 55 to 60 parts of aggregate with the particle size of 9.5 to 13.2 mm; 15 to 20 parts of aggregate of 13.2 to 16 mm; 2 to 2.5 parts of a polyurethane cementing material; 1 to 1.5 parts of mineral powder; the high-performance cement-based grouting material comprises the following raw materials in parts by mass: 45-50 parts of cement; 20 to 25 parts of water; 3 to 5 parts of fine sand of 0.15 to 0.3 mm; 2-3 parts of epoxy resin; 0.5 to 1 part of silica fume; 0.5 to 1 part of polypropylene fiber; and 0.5-1 part of a water reducing agent. The asphalt pavement pit slot repairing material with high durability and early strength characteristics is relatively good in applicability, can quickly complete repairing and open traffic under various environmental conditions, and can have relatively good strength and durability in the later period.
一种沥青路面坑槽用修补材料，包括大孔隙基体混合料和高性能水泥基灌浆材料；其中，所述大孔隙基体混合料包括以下质量组分的原料：4.75～9.5mm集料15～20份；9.5～13.2mm集料55～60份；13.2～16mm集料15～20份；聚氨酯胶结料2～2.5份；矿粉1～1.5份；所述高性能水泥基灌浆材料包括以下质量组分的原料：水泥45～50份；水20～25份；0.15～0.3mm细砂3～5份；环氧树脂2～3份；硅灰0.5～1份；聚丙烯纤维0.5～1份；减水剂0.5～1份。本发明具有高耐久性、早强特性的沥青路面坑槽修补用材料的适用性较好，可在多种环境条件下快速完成修补并开放交通，且后期均可具有较好的强度和耐久性。
