Abstract Pervious concrete is emerging as an alternative material for paving to help curtail nonpoint source pollution problems. The porosity of pervious concrete is an important variable needed for pavement system design and for material comparisons. This paper researches a method for measuring the porosity of pervious concrete from field-obtained cores by applying the Archimedes principle and using standard materials laboratory equipment. The error between different operators at different testing facilities was found to be around 2.2 % porosity.
