Problems solved by technology

[0002] Epoxy asphalt material has long been a mature product in foreign countries. Most of the epoxy asphalt used in my country is still imported from the United States. Its main disadvantages are high price, complicated construction technology, and single product formula, which have affected the quality of epoxy asphalt. Wider applications of asphalt
Although some progress has been made in domestic research on it, overall, the research on epoxy asphalt in my country is still in its infancy. etc. The selection has not been well resolved. According to literature reports, the weight ratio of epoxy resin to asphalt in epoxy asphalt binder and binder is 1:2.8 and 1:2.45, which is far lower than that of imported epoxy asphalt 1:5.85. And the ratio of 1:4.45, so the cost is higher, and the material performance is much lower than that of imported products

Abstract

The invention relates to epoxy asphalt for roads and bridges and a preparation method for the same, which belong to the technical field of modified asphalt for the roads and the bridges, adopt novel modified epoxy resin, and are good in compatibility and large in asphalt filling amount. The technical scheme includes that the epoxy asphalt for the roads and the bridges is made of, by weight, a component A of modified epoxy resin and a component B including 45-85 parts of heavy traffic paving asphalt, 3-25 parts of fatty acid anhydride, 8-30 parts of fatty group binary acid, 1-20 parts of monomer mixtures, 5-40 parts of modified epoxy resin and 0.1-1.2 parts of curing accelerator, the weight part ratio of the component A to the component B is 1:2-12, and the modified epoxy resin is made of, by weight, 3-9 parts of epoxy resin, 2-8 parts of furfuryl alcohol mud, 0.5-3 parts of polyester and 0.5-3 parts of furfuryl alcohol. The epoxy asphalt for the roads and the bridges is widely applied to the field of paving of road surfaces and bridge surfaces.

Description

technical field [0001] The epoxy asphalt for roads and bridges and the preparation method thereof of the invention belong to the technical field of modified asphalts for roads and bridges. Background technique [0002] Epoxy asphalt material has long been a mature product in foreign countries. Most of the epoxy asphalt used in my country is still imported from the United States. Its main disadvantages are high price, complicated construction process and single product formula, which have affected the epoxy wider application of asphalt. Although some progress has been made in domestic research on it, overall, the research on epoxy asphalt in my country is still in its infancy, due to the compatibilizer, curing agent, diluent, accelerator and reinforcing agent etc. The selection has not been well resolved. According to literature reports, the weight ratio of epoxy resin to asphalt in epoxy asphalt binder and binder is 1:2.8 and 1:2.45, which is far lower than that of imported e...
