UHPC (Ultra High Performance Concrete) ground material, gap type permeable pavement and paving method of gap type permeable pavement
The invention discloses a UHPC (Ultra High Performance Concrete) ground material, a gap type permeable pavement and a paving method thereof, the UHPC ground material comprises the following components in percentage by weight: 32-37% of Portland cement, 20-24% of superfine fly ash, 4-8% of a shrinkage enhancer, 1-2% of bentonite, 1-2% of silica fume, 10-20% of quartz sand aggregate and 8-10% of rubber particles, the coating is prepared from, by weight, 2%-5% of nanoscale pure acrylic emulsion, 0.2%-0.4% of a retarder, 0.02%-0.05% of a water reducing agent, 1%-2% of redispersible latex powder, 1%-1.5% of polyvinyl alcohol fibers, 2%-4% of polyimide resin and 0.3%-0.4% of a waterproof agent. The UHPC ground material disclosed by the invention also has excellent crack resistance and tensile strength during thin-layer pavement, can meet the joint cutting requirement, and fills the blank of no cast-in-place gap type permeable pavement at present when being applied to the cast-in-place gap type permeable pavement.
本发明公开了一种UHPC地面材料、缝隙式透水路面及其铺装方法，该UHPC地面材料包括以下重量百分比的组分：硅酸盐水泥32％‑37％，超细粉煤灰20％‑24％，减缩增强剂4％‑8％，膨润土1％‑2％，硅灰1％‑2％，石英砂骨料10％‑20％，橡胶颗粒8％‑10％，纳米级纯丙烯酸乳液2％‑5％，缓凝剂0.2％‑0.4％，减水剂0.02％‑0.05％，可再分散性乳胶粉1％‑2％，聚乙烯醇纤维1％‑1.5％，聚酰亚胺树脂2％‑4％，防水剂0.3％‑0.4％。本申请UHPC地面材料，在薄层铺装时同样具有优异的抗裂抗拉强度，可满足切缝要求，将其应用于现浇缝隙式透水路面，填补了目前无现浇缝隙式透水路面的空白。
