Anti-crack rubber powder fiber cement stabilized macadam base material

The invention relates to the crossing field of material science and road engineering, and discloses an anti-crack rubber powder fiber cement stabilized macadam base material, which is prepared from the following raw materials in percentage by weight: 30 to 45 percent of PO52.5 Portland cement, 10 to 20 percent of 80 to 120-mesh asphalt, 10 to 20 percent of 40 to 80-mesh quartz sand, 15 to 30 percent of 20 to 40-mesh carborundum, 15 to 30 percent of 10 to 20-mesh polypropylene fiber and 1 to 3 percent of water reducing agent. The composite material comprises the following components in percentage by weight: 6-8% of wood fiber, 3-5% of polymer nano rubber powder, 5-8% of sodium metasilicate nonahydrate and 5-20% of inorganic toner A sealing wear-resistant layer and a water retention layer are formed on the surface of newly-poured asphalt through microcapsules, so that the strength of the newly-poured asphalt is improved under a good condition, meanwhile, the microcapsules added inside can perform self-repairing
