Abstract

The invention discloses high-performance epoxy asphalt. The epoxy asphalt is prepared from asphalt, epoxy resin, 4,4-diaminodiphenylmethane, fumaric acid, benzyl dimethylamine, glacial acetic acid, ammonium humate, styrene-acrylonitrile copolymer, EO-PO segmented copolymer, polyurethane, TNPP, polyoxyethylene stearate, polyisoprene rubber powder, rosin, sulphobetaine, resorcinol diglycidyl ether, sodium gluconate and octamethylcyclotetrasiloxane. The invention further discloses a preparation technology of the high-performance epoxy asphalt. The asphalt prepared through the method is low in viscosity, not likely to be layered and good in storage stability, the tensile strength of the epoxy asphalt is 7.16-10.62 MPa, the breaking elongation rate is 510-658%, the epoxy asphalt shows good strength and toughness, early strength can be improved to a certain degree, construction is convenient, and large-scale application and popularization are promoted.

Description

technical field [0001] The invention belongs to the technical field of asphalt for road construction, and in particular relates to a high-performance epoxy asphalt and a preparation process thereof. Background technique [0002] With the rapid development of social economy, the increase of vehicle axle load and the increase of traffic volume, the driving of road traffic and the deterioration of the environment, most of the asphalt concrete roads will have damage phenomena such as rutting, hugging, pushing and cracking, which are serious It shortens the service life of asphalt concrete roads and restricts the development of road construction in China. The main reason for the above damage is that the stability, aging resistance, fatigue resistance and water damage resistance of the matrix asphalt material cannot meet the current road construction and application requirements. [0003] Epoxy asphalt is a new type of asphalt material mixed with epoxy resin, curing agent and bas...
