Problems solved by technology

[0002] The problem of early disease of steel bridge deck pavement has always been a worldwide problem, and there is still no complete solution
At present, the commonly used construction materials and construction techniques mainly include the use of hot-mixed epoxy asphalt materials, single-layer pouring technology, and composite pouring asphalt pavement technology. Although the early disease problems of steel bridge deck pavement have been alleviated to a certain extent, However, due to technical bottlenecks such as high cost and inconvenient operation, its popularization and application are limited.
[0003] Invention ZL200610039988.8 provides a hot-mix epoxy asphalt pavement material, and invention ZL200910247718.X provides a warm-mix epoxy asphalt pavement material, mainly by adding a large amount of asphalt to improve the flexibility of epoxy resin , but all need to use hot mixing process, which is inconvenient to operate and relatively expensive

Abstract

The invention discloses a high-toughness cold-mixing modified resin material for paving roads and bridges and a preparation method of the high-toughness cold-mixing modified resin material. The high-toughness cold-mixing modified resin material is composed of a component A and a component B, wherein the mass ratio of the component A to the component B is 10:(8-13); the component A comprises 10-20 parts of epoxy resin, 1-5 parts of a diluent and 1-5 parts of an active toughening agent; and the component B comprises 5-15 parts of a normal-temperature flexible curing agent, 1-5 parts of asphalt, 3-8 parts of a solubilizer and 1-3 parts of filler. The invention provides the high-toughness cold-mixing modified resin material for paving roads and bridges; the high-toughness cold-mixing modified resin material is more convenient to construct and is not needed to be heated, the raw materials are mainly softened by using compound toughening materials including a rubber toughening agent, toughening filler and a flexible curing agent, and the performances of the high-toughness cold-mixing modified resin material are same as those of hot-mixed or warm-mixed epoxy asphalt, so that the high-toughness cold-mixing modified resin material provides a technical reference for specially paving bridge decks, airfield pavements and the like.
