Abstract

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.

Description

technical field [0001] The invention relates to a semi-flexible pavement material and a method for paving the pavement, which belongs to the technical field of road rut disposal, and is especially suitable for the rut disposal of special road sections such as municipal road intersections and bus lanes. Background technique [0002] The traditional cement concrete pavement has good bearing capacity, but poor flexibility, prone to plate cracking, mud pumping and other diseases, and needs to be equipped with expansion joints, which affects driving comfort. Although the asphalt concrete pavement has better flexibility, it is prone to rutting at high temperature, which affects driving safety and comfort. In order to overcome the shortcomings of the above two traditional pavements, a semi-flexible pavement is produced, which is a new pavement material composed of large-pore asphalt mixture and cement-based grouting material. Semi-flexible pavement is a kind of rigid and flexible ...
