Porous Pavement Rehabilitation Project

Friday, October 18, 2019

The UNH Stormwater Center in cooperation with Triverus and UNH Facilities conducted a product demonstration and subsequent quantification of the effectiveness of an enhanced vacuuming technology by Triverus called the municipal cleaning vehicle.  Overall, the restoration effort was extremely successful.  Our research supports further exploration of restoration activities followed by more routine operation and maintenance such as vacuum sweeping twice per year.  This data also reveals some significant differences in the pollutant partitioning between the liquid and solid fractions of the removed materials.  It underscores the importance, particularly in nitrogen-sensitive areas, of properly treating the removed waste materials.
