Abstract
Pervious concrete is very different from traditional portland-cement concrete (PCC). Therefore here are open questions regarding the suitability of the current standard concrete testing protocols as they may be applied to pervious concrete. There are unique features associated with pervious concrete that may require special testing considerations. This paper examines the compaction and consolidation of pervious concrete. This study presents cylindrical specimen preparation techniques that will produce laboratory specimens that are similar to the field pervious concrete slab. Additionally, a simple correlation is provided that allows concrete designers to estimate the porosity of pervious concrete based on its aggregate bulk density when crushed limestone is used This practical tool saves time when designing pervious concrete mixtures.
