Description

technical field [0001] The invention belongs to pavement pavement materials, in particular to a thin-layer pavement material suitable for wet road and bridge decks and a preparation method thereof. Background technique [0002] Epoxy resin thin-layer pavement refers to the anti-skid and wear-resistant thin-layer pavement with a thickness of only 3-6mm formed by bonding epoxy resin adhesive as the bottom layer and wear-resistant aggregate. In foreign countries such as the United States, due to the relatively long development time of related industries and relatively mature technology, there are currently many products available, with good performance and durability, but the scale is small, and they have a high impact on the application base. It is required to ensure that the moisture content of the base surface is below 8%. At present, the research and development of epoxy thin-layer overlays in China is still in its infancy, and the experimental section of modified epoxy re...
