Abstract

The invention discloses organosilicone modification epoxy asphalt. The organosilicone modification epoxy asphalt comprises a component A and a component B. The component A comprises, by mass, 100 parts of mixtures of organosilicone resin and epoxy resin and 5 parts to 10 parts of organosilicone coupling agents, wherein the mass ratio of the organosilicone resin to the epoxy resin is 10-15 to 85-90. The component B comprises, by mass, 45 parts to 135 parts of curing agents, 4.5 parts to 13.5 parts of diluents, 0 part to 0.02 part of accelerants and 100 parts to 150 parts of asphalt. On the basis of the steps, mineral materials are mixed into the prepared organosilicone modification epoxy asphalt, stirring is carried out at 100 DEG C to 150 DEG C, and an organosilicone modification epoxy asphalt mixture is obtained. The invention further discloses a method for preparing the organosilicone modification epoxy asphalt mixture and application of the organosilicone modification epoxy asphalt mixture to steel bridge and cement concrete bridge deck pavement, asphalt road surface pavement and repairing and special sections such as intersections and parking stations.

Description

technical field [0001] The invention relates to an organosilicon modified epoxy asphalt and a mixture. [0002] The present invention also relates to the preparation method of the silicone modified epoxy asphalt and the mixture. [0003] The present invention also relates to the application of the silicone-modified epoxy asphalt mixture. Background technique [0004] With the rapid development of my country's economy, the traffic volume is increasing day by day, and the phenomenon of overloading is prominent, which puts forward higher requirements for the pavement structure and materials, and the early damage and structural damage of the road frequently occur. Compared with conventional pavement, steel bridge deck pavement has the characteristics of large deformation, unfavorable force, smooth steel plate, and large traffic volume. The force is complex, the maximum tensile stress or strain of the pavement layer may appear on the surface of the pavement layer, and the requi...
