Investigation into Laboratory Abrasion Test Methods for Pervious Concrete

摘要: Portland cement pervious concrete (PCPC) has been increasingly used in pavements during recent years. In addition to strength and permeability, abrasion durability is another important property of PCPC. this study, three laboratory test methods were investigated for their potential capability evaluating the raveling resistance The tests are Cantabro test, loaded wheel surface test. To evaluate methods, eight PCPC mixtures containing different sizes coarse aggregates additives tested. comparison indicates that all fairly effective differentiating between mixtures. However, results from may not reflect because failure specimens was caused by impact rather than abrasion. With studded wheels increased load, exhibited best sensitivity sufficient repeatability. successfully differentiated control mix other mixtures, but failed differentiate latex and/or fiber, which be attributed unfavorably low weight loss values
