摘要

The use of pervious concrete pavement (PCP) is significantly increasing due to reduction of road runoff and absorption of traffic noise. However, this type of pavement cannot be used for heavy traffic due to a high amount of voids and consequently low strength. This study focuses on the use of by-products as fine additives such as silica fume (SF) and fly ash (FA) for evaluating their effect on the mechanical and durability properties of PCP as an attempt to establish a balance between permeability and strength properties. The effect of coarse aggregate size, ratio of fine aggregate, specimen's size and curing periods were investigated. The results indicate that PCP provided acceptable permeability of 3.6 mm/s and 28 day compressive strength reaching to 33.0 MPa through the combination of FA and SF.
