Abstract

The invention discloses a biological epoxy asphalt, which includes three components A, B and C, A component includes epoxy soybean oil and diluent, B component includes curing agent, accelerator and defoamer, C The components include asphalt; wherein, the mass ratio of component A to component B is 105-126:45, and the mass ratio of the sum of the masses of components A and B to the mass of component C is 100:57-520. Compared with the prior art, the bio-epoxy asphalt of the present invention can replace traditional petroleum asphalt, and materials such as epoxy soybean oil and biological curing agent are used, which can effectively improve the thermoplastic properties of traditional asphalt materials while significantly reducing costs , so it has excellent high and low temperature performance and anti-aging characteristics, and can be widely used in road pavement such as roads and tunnels and bridge deck pavement. The invention discloses its preparation method.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a biological epoxy asphalt and its preparation method and application. Background technique [0002] Epoxy asphalt is a three-dimensional continuous phase thermosetting material formed by an irreversible chemical crosslinking and curing reaction of epoxy resin, curing agent, and petroleum asphalt. As the temperature rises, epoxy asphalt will not soften like traditional asphalt, and has good aging resistance and chemical corrosion resistance. The fatigue performance of epoxy asphalt concrete is three orders of magnitude greater than that of Superpave polymer modified asphalt concrete, which can be easily It is suitable for heavy load, large traffic volume and wide-area temperature, which greatly improves road performance. On the other hand, as an alternative product of traditional petroleum asphalt, bio-asphalt can be made from a variety of biomass materials, such as wheat...
