Problems solved by technology

[0003] However, with the widespread use of high-performance epoxy asphalt materials on steel bridge decks and the increase in the number of years of traffic, the pavement of epoxy asphalt steel bridge decks will also have various diseases, such as cracking, slurrying, bulging, potholes, and network cracks. , cracks, etc. Among them, cracks and bulges are the most common diseases. If the bulges are not treated in time, they will develop into potholes and affect the normal use of the bridge.
Since the research on epoxy asphalt steel bridge deck pavement started late in our country, most of the epoxy asphalt materials used were imported from abroad. There is even a lack of materials for repairing potholes in epoxy asphalt pavement

Abstract

The invention discloses a cold mix epoxy resin material for quickly repairing epoxy asphalt pavement pits. The cold mix epoxy resin material comprises a component A and a component B, wherein the component A mainly comprises epoxy resin, an active diluent, a coupling agent, a thixotropic agent and a reinforcing agent, and the component B mainly comprises a curing agent, an accelerant, a thixotropic agent, a defoaming agent and a toughening agent. The mass ratio of the component A to the component B is 100: (200 to 100): 260, a mixture of components A and B is mixed with aggregate to obtain a cold mix epoxy resin mixture, and the mass ratio of the sum of the A component and the B component to the aggregate is 16:84 to 19:81. The cold mix epoxy resin material for quickly repairing epoxy asphalt pavement pits disclosed by the invention has the advantages of high bonding strength, good toughness, good waterproofness, normal temperature mixing, simple construction process, short open traffic time, energy conservation, environmental protection, etc. The cold mix epoxy resin material disclosed by the invention is mainly suitable for quickly repairing epoxy asphalt pavement pits and suitable for quickly repairing such pavements as high grade highways, tunnels, airport runways, cement concrete bridge decks, etc. The invention discloses a preparation method of the cold mix epoxy resin material.

Description

technical field [0001] The invention relates to a cold-mixed epoxy resin material for rapid repair of potholes in epoxy asphalt paving layers, a preparation method and an application method thereof. Background technique [0002] High-performance epoxy asphalt material is a kind of polymer modified asphalt material, which uses high-performance epoxy resin and its curing agent as asphalt modifier. When the epoxy resin in the asphalt reacts with the curing agent, an irreversible three-dimensional network cross-linked structure will be formed. At this time, the asphalt is firmly bound in the cross-linked network formed by the epoxy resin, so that the asphalt cannot flow, and the crack resistance of asphalt is also greatly improved at low temperature, which fundamentally changes the thermoplastic behavior of asphalt and endows asphalt with excellent performance. Therefore, high-performance epoxy asphalt materials have the characteristics of high strength, good toughness, excelle...
