The current research is focusing on comparing the two types of porous pavements. This is a holistic study that will consider installation, durability, water quantity, and water quality. Each pavement area is highly instrumented and data is being recorded 24 hours a day.
The durability of each surface is being monitored quarterly for any signs of surface spalling and clogging of void space. The current water quantity data is focusing on the infiltration of each pavement system (pavement and stone bed) for different storm events. For the water quality testing we gather samples at several locations (before entering the pavement, in the storage bed, and in the soil under the beds) for all storms over 0.25 in. Currently, we are testing the water samples for:
