Early strength type semi-flexible pavement
The invention discloses an early strength type semi-flexible pavement which is formed by piling up a cement-based grouting material. The cement-based grouting material comprises, by mass, 40-50 partsof slag, 15-20 parts of fly ash, 30-40 parts of water glass, 25-35 parts of silica fume, 2-5 parts of limestone mineral powder; 6-8 parts of graphene, 14-18 parts of epoxy resin, 6-8 parts of metakaolin, 2-5 parts of ethylenediamine tetraacetic acid, 8-10 parts of phthalic anhydride, 6-8 parts of trimethylolpropane, 3-5 parts of rubber powder, 3-5 parts of bauxite, 2-4 parts of iron oxide yellow,0.5-1 part of calcium hydroxide, 5-10 parts of modified plant fibers, 15-20 parts of glycerol and 10-20 parts of water, wherein the content of SiO2 in the silica fume is greater than or equal to 92wt.%. The early strength type semi-flexible pavement is formed by piling up the cement-based grouting material, the obtained semi-flexible pavement has good high-temperature rutting resistance, low-temperature cracking resistance, water damage resistance and fatigue resistance, and the service lifetime of the pavement can be prolonged.
本发明公开了一种早强型半柔性路面，采用水泥基灌浆材料堆砌而成，水泥基灌浆材料由如下质量份数的组分组成：40～50份矿渣、15～20份粉煤灰、30～40份水玻璃、25～35份硅灰、2～5份石灰岩矿粉、6～8份石墨烯、14～18份环氧树脂、6～8份偏高岭土、2～5份乙二胺四乙酸、8～10份邻苯二甲酸酐、6～8份三羟甲基丙烷、3～5份胶粉、3～5份铝矾土、2～4份氧化铁黄、0.5～1份氢氧化钙、5～10份改性植物纤维、15～20份甘油以及10～20份水。其中，所述硅灰中SiO含量≥92wt.％。本发明早强型半柔性路面采用上述水泥基灌浆材料堆砌而成，得到的半柔性路面具有良好的高温抗车辙、低温抗开裂、抗水损坏、抗疲劳性能，能够延长路面的使用寿命。
