Void ratio and durability properties of porous polymer concrete using recycled aggregate with binder contents for permeability pavement

Particularly in Korea, where most roads are paved with impermeable materials such as asphalt and cement concrete, problems arise such as increased flooding as result of rainwater flowing into urban streams and the depletion of underground water. In recent years, there has been a great deal of ongoing research concerning water permeability and drainage in pavements. Accordingly, in this research, a porous polymer concrete was developed by using unsaturated polyester resin as a binder, recycled aggregate as coarse aggregate, fly ash and blast‐furnace slag as filler for permeable pavement, and its physical and mechanical properties were investigated. Regardless of the type of filler and amount of binder, the standard void ratio of 8% specified in the mixture of permeable asphalt was exceeded. In all mixes, regardless of the type of filler and amount of binder, the standard compressive strength for permeable concrete of 18 MPa was exceeded. Also, in all mixes, the standard permeability coefficient of 1.0 × 10−2 cm/s for permeable asphalt mixture was exceeded. The weight reduction ratio of the porous polymer concrete that was submerged in 10% sulfuric acid solution was 1.17 to 2.3%, and it was found that there was virtually no weight reduction. © 2012 Wiley Periodicals, Inc.
