Infiltration and structural tests of permeable eco-paving
This paper describes laboratory evaluations of the infiltration and structural characteristics of two forms of interlocking concrete eco-pavers. These were tested in combination with five bedding, jointing and drainage materials ranging from a 2mm sand to a 10mm gravel. It was found that the test pavements could accept rainfall intensities of up to about 600 l/ha/sec when the drainage material comprised a uniform 5mm gravel, but that the addition of fines or sands to the drainage medium substantially reduced water infiltration. Water penetration appeared to be largely independent of the type of eco-paver or the pavement cross fall. When using gravels with a maximum size around 5mm the test pavements achieved values of stiffness that were comparable with those measured in similar tests of conventional concrete pavers. Overall, the tests indicated that eco-pavers are likely to prove a viable alternative to conventional segmental pavement materials in trafficked pavements.
