TL;DR: In this article, the effect of mixture design on strength of pervious concrete and its effect of clogging materials on the coefficient of permeability was investigated, and the use of the dynamic pressurization test was used to evaluate the durability.
Abstract: Although pervious concrete was first used in the nineteenth century, it has only recently begun to increase in popularity. As urban areas expand, the problems associated with runoff management have become more challenging. The focus on the negative environmental effects associated with pavement runoff has also increased. These two issues have spurred the recent interest in pervious concrete pavements; pervious concrete, however, has deficiencies which limit its application as pavements. These limitations include low compressive strength, flexural strength, clogging, and other durability issues. The overall purpose of this project was to provide tools to evaluate and improve the durability and strength of pervious concrete such that it may be more confidently employed in urban roadways. The specific objectives of this project were to (a) investigate the effect of mixture design on strength of pervious concrete (including the effect of fibers), (b) evaluate effect of clogging materials on coefficient of permeability, (c) and investigate the use of the dynamic pressurization test to evaluate the durability of pervious concrete. This report documents the results of the laboratory testing, and presents recommendations for mixture proportioning. In addition, recommendations are provided for optimizing the balance between compressive strength and permeability.

TL;DR: In this paper, the fracture test of pervious concrete mixes with porosity around 19.5% showed that the fracture energy increases with increasing the dosage of polymer, reflecting the ductile damage features rather than brittleness.
Abstract: Compressive and flexural strength, fracture energy, as well as fatigue property of pervious cement concrete with either supplementary cementitious materials (SCMs) or polymer intensified, were analyzed. Test results show that the strength development of SCM-modified pervious concrete (SPC) differs from that of polymer-intensified pervious concrete (PPC), and porosity has little effect on their strength growth. PPC has higher flexural strength and remarkably higher flexural-to-compressive strength ratio than SPC at the same porosity level. Results from fracture test of pervious concrete mixes with porosity around 19.5% show that the fracture energy increases with increasing the dosage of polymer, reflecting the ductile damage features rather than brittleness. PPC displays far longer fatigue life than SPC for any given failure probability and at any stress level. It is proved that two-parameter Weibull probability function describes the flexural fatigue of pervious concrete.

TL;DR: In this paper, a series of air system characterization tests performed during a field placement of pervious concrete is detailed, and the test results are compared, based on the results of the study, determination of air systems for the freeze-thaw protection of perviously concrete is proposed.
Abstract: Portland cement pervious concrete is becoming a common tool for stormwater management across the United States. The air void system in pervious concrete is particularly important because of its effect on stormwater infiltration, concrete strength, and long-term durability. However, currently the concrete industry lacks standardized testing techniques for characterizing air void systems in pervious concrete. In this paper a series of air system characterization tests performed during a field placement of pervious concrete is detailed, and the test results are compared. Fresh pervious concrete samples from two delivered mixtures were evaluated using pressure, volumetric, Chace, and air void analyzer air test methods. The hardened concrete samples were tested for water-permeable void content, water permeability, air voids (using ASTM Standard C457 method), and freeze-thaw durability (using ASTM Standard C666A method). Based on the results of the study, determination of air systems for the freeze-thaw protection of pervious concrete is proposed.
