Pervious concrete pavements have good drainage and noise reduction capabilities; however, the low freezing-thawing resistance is an intrinsic weakness of pervious concrete. The study mainly focuses on the effects of admixtures on the compressive strength and freezing-thawing resistance of pervious concrete. Five admixtures, including fly ash, silica fume, mineral powder, ethylene vinyl acetate (EVA) latex, and polyethylene fiber were used in the tests, and the effect of 0%, 2%, 5%, 6%, 8%, and 10% weight percentages as a cement replacement in concrete mixtures on the freezing-thawing resistance was studied. The results indicated increase trends in freezing-thawing resistance of the pervious concrete specimens with the admixtures added.
