In the U.S. and around the world, large amounts of waste latex paint are generated annually, which creates a significant challenge in terms of disposal in an economic manner. Paint contains some chemicals that may be harmful to the environment if recycled as it contains volatile organic compounds. However, waste latex paint can be used to produce an economic latex-modified pervious concrete that is similar or superior to regular pervious concrete. Previous studies investigated recycling waste latex paint in concrete applications such as sidewalks. This study investigates the use of waste latex paint in producing pervious concrete and the effect of using different ratios of paint addition on the properties of the studied mixtures. The properties evaluated included physical, mechanical and hydraulic properties. Results show that while waste latex paint recycling in pervious concrete can slightly reduce its mechanical properties at 5% polymer to cement content, it can still be a viable option to prevent paint disposal in landfills.
