Abstract

The invention discloses a permeable asphalt admixture, permeable asphalt and a permeable asphalt pavement. The preparation raw materials of the permeable asphalt admixture comprise the following components in parts by weight: 0.5 to 1.5 parts of an emulsifying agent, 1 part of a dispersing agent, 2 to 4 parts of a capillary pore forming agent and 0.01 to 0.06 part of a catalyst. The permeable asphalt is prepared by uniformly mixing the permeable asphalt admixture and asphalt. The permeable asphalt pavement contains the permeable asphalt admixture. According to the permeable asphalt admixture,the permeable asphalt and the permeable asphalt pavement, the problems of early loosening, easiness in gap blockage in use, low strength, great construction difficulty and high cost in the existing permeable asphalt pavement are solved, and the permeable asphalt pavement has the advantages that the construction performance is excellent, the cost is low, the constructed permeable asphalt pavement is compact in structure and high in strength, gaps are not easily blocked in use, the continuous permeability is high, and the anti-fouling and anti-blockage performance is high.

Description

technical field [0001] The invention relates to the technical field of permeable asphalt, in particular to a permeable asphalt additive, a permeable asphalt and a permeable asphalt pavement. Background technique [0002] Permeable asphalt pavement has the advantages of reducing noise, reducing water mist and glare, waterproof drifting, improving the visibility of road signs and improving the skid resistance of wet pavement, so it is also called "drainage and noise reduction pavement", which is a new pavement structure . [0003] Currently, permeable asphalt pavement is made by mixing specially developed modified asphalt, slaked lime, and fibers into the raw materials. The existing permeable asphalt pavement has the disadvantages of early looseness, easy clogging of voids during use, low strength, difficult construction, and high cost. Contents of the invention [0004] In order to solve the problems existing in the existing permeable asphalt pavement such as early loosen...
