▎ 摘  要

NOVELTY - Early-strength semi-flexible pavement comprises cement-based grouting material containing 40-50 pts. wt. slag, 15-20 pts. wt. fly ash, 30-40 pts. wt. sodium silicate, 25-35 pts. wt. silica ash, 2-5 pts. wt. limestone mineral powder, 6-8 pts. wt. graphene, 14-18 pts. wt. epoxy resin, 6-8 pts. wt. metakaolin, 2-5 pts. wt. ethylenediaminetetraacetic acid, 8-10 pts. wt. phthalic anhydride, 6-8 pts. wt. trimethylolpropane, 3-5 pts. wt. rubber powder, 3-5 pts. wt. bauxite, 2-4 pts. wt. yellow iron oxide, 0.5-1 pts. wt. calcium hydroxide, 5-10 pts. wt. modified plant fiber, 15-20 pts. wt. glycerol and 10-20 pts. wt. water. USE - Used as early-strength semi-flexible pavement. ADVANTAGE - The pavement: has excellent high-temperature rutting resistance, low-temperature resistance to cracking, water damage, and fatigue resistance; and can extends the service life of the road surface.
