RMC Foundation Releases Report on Pervious Concrete

The RMC Research & Education Foundation has released its latest pervious concrete research report, Predictive Model for Void Content and Strength of Pervious Concrete Pavements Installed in the Field. Performed by researchers at Washington State University, the project includes the development of a model that may be used to predict the void content and compressive strength of pervious concrete field installations based on mixture composition and the compaction level. Installers can use a database of their mixture composition, roller screed weight, revolutions per minute, void content and strength of cores from past projects to recalibrate the developed model. The calibrated model can then forecast the required compaction to produce the target void content and strength. The project included both laboratory and field testing and looked at several variables, including roller screed weight and the number of passes.
