Performance tests are conducted on pervious concrete mixed with Polypropylene Split Fiber (PPSF), in which basic indexes such as compressive strength, splitting strength, flexural strength, porosity, permeability coefficient are measured. Results indicate: mixed with certain amount of PPSF in ordinary pervious concrete is feasible, and during mixing PPSF is split into uniformly distributed monofilament fiber without occurrence of agglomeration or rustiness; incorporating 3kg PPSF in 1m3 pervious concrete is proper, under which compared with the ordinary pervious concrete, both porosity and permeability coefficient are decreased, but application requirements are still met, while strength is increased obviously; the pervious concrete mixed with PPSF can be used in ordinary light traffic pavements.
