Abstract

The invention discloses an antiskid permeable pavement which comprises a pavement base layer and an adhesive stone surface layer paved on the surface of the pavement base layer, the adhesive stone surface layer is prepared from the following raw materials in parts by weight: 2-5 parts of a component A, 3-7 parts of a component B and 95-105 parts of aggregate; the component A is prepared from the following raw materials: polyester of aliphatic dicarboxylic acids, polyether polyol, dipropylene glycol, neopentyl glycol, linoleic acid, castor oil, 2,2,3,3,4, 4,5,5-octafluoro-1-amyl alcohol, epoxyresin E-44, epoxy resin E-14, diphenyl-methane-diisocyanate, hexamethylene diisocyanate, nano silicon dioxide, nano calcium carbonate, boron carbide and modified lignin; the component B is prepared from the following raw materials: 1,8-diazacyclo[5,4,0]undecene-7 and triethanolamine. The anti-skid permeable pavement provided by the invention has the advantages of good skid resistance and water permeability, excellent aging resistance, short curing time and long service life.

Description

technical field [0001] The invention relates to the technical field of roads, in particular to an anti-skid permeable road surface. Background technique [0002] Urban waterlogging has become an unavoidable and heavy topic every summer, and it is getting worse. Permeable pavement adopts the method of "seepage" to absorb rainwater on the spot or infiltrate into the ground or directly discharge it into the municipal drainage system, which can significantly reduce the occurrence of waterlogging. More and more cities have begun to use permeable pavement as urban roads and The preferred paving material for floors in public areas. Adhesive stone permeable pavement is one of the current methods of permeable pavement. It is a permeable pavement material made of cementitious aggregates. It has the advantages of high water permeability and porosity, but its aging resistance is poor. It is easy to fall off and has a short lifespan, which limits its application.
