摘要：

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.
