Abstract

Various methods for compressive strength and hydraulic testing for pervious concrete were investigated. No statistically significant differences were found in compressive strength measurements between elastomeric pad- and sulfur-capped specimens; due to the simpler preparation method, elastomeric pad capping is recommended. Statistically significant differences were observed in compressive strength measurements between specimens with a length-diameter ratio (L D) of 2:1 and 1.5:1. Specimens with an L D of 1:1 produced inconsistent strength measurements. Hydraulic conductivity correlated linearly to the infiltration rates from single ring, double ring and falling head infiltrometers, and was smaller than the infiltration rates by factors of 1.8, 1.5, and 9.0, respectively, for 6 in. (152 mm) thick pervious concrete. The falling head infiltrometer can be used for a quick estimate of infiltration rate; if used, its measurement can be divided by 5 to estimate infiltration rate from the single ring infiltrometer.
