Effectively Estimating In situ Porosity of Pervious Concrete from Cores

CODEN: JAIOAD

Abstract

Pervious concrete is an alternative pavement material which may help reduce nonpoint source pollution problems. The porosity of pervious concrete is an important parameter used for both pavement and environmental design and is dependent on field placement techniques. It is recommended that porosity be tested on field-placed specimens. It has been noted that some of the concrete is knocked out while coring from field-placed samples which may affect the porosity. This paper researches a methodology for estimating the in situ porosity of pervious concrete from the porosities of cores taken from the field based on aggregate size, core size and porosity.
