Half-flexible pavement material for rapid traffic opening and method of half-flexible pavement material for paving pavement
The invention discloses a half-flexible pavement material for rapid traffic opening and a method of the half-flexible pavement material for paving a pavement. The half-flexible pavement material comprises a porous mixed material and a cement-based grouting material filled into pores of the porous mixed material, wherein the porosity of the porous mixed material is 16-23%; the porous mixed material consists of the following components in percentage by mass: 3.5-7% of aqueous epoxy resin, 0.5-2.5% of flexible latex, 87-92% of aggregate and 3.5-5% of mineral powder; the cement-based grouting material consists of the following components in percentage by mass: 35-50% of rapidly hardened sulfate aluminum cement, 25-45% of grinded slag powder, 0.15-0.35% of a water reducing agent, 1-2.5% of a shrinkage reducing agent and 18-25% of water. By adopting the half-flexible pavement material for rapid traffic opening, normal temperature construction can be achieved in the whole process, only 2-4 hours are taken when the aqueous epoxy resin porous mixed material is mixed until the traffic of a half-flexible pavement is opened, and the half-flexible pavement material is excellent in track resistance, relatively long in service life, low in repairing expense, very wide in application prospect and high in use value.
