Abstract

The invention discloses a rapid dehydration curing agent as well as a preparation method and an application thereof. The rapid dehydration curing agent is formed by mixing anti-stripping agent powder, mineral powder, polymer rubber powder and cement. After the curing agent is added to a mixture, normal-temperature asphalt concrete is rapidly dehydrated and cured, and has a high elastoplastic surface layer and excellent weather resistance, so that the problems that the traditional modified emulsified asphalt concrete is slowly dehydrated and not easily cured are solved, and thus the construction efficiency and the social benefits are greatly improved.

Description

technical field [0001] The invention belongs to the field of newly repaired normal-temperature asphalt surface layer and road maintenance and repair, and specifically relates to a fast dehydration curing agent and its preparation method and application. Background technique [0002] At present, the general modified emulsified asphalt mixture on the market in our country has a slow process of strength formation. It has plasticity and fluidity during paving and rolling, and can be squeezed to irregular places in pits. Under the action of driving and air, the water only depends on volatilization, the asphalt gradually thickens, the distribution of room temperature asphalt mixture particles is tighter, the porosity is reduced, the mutual bonding of mineral materials is stronger, and the density of the mixture increases. This process takes several days, after which the strength will gradually increase. After a period of time, its deformation and strength will gradually stabilize,...
