Porous asphalt pavements offer an alternative technology for stormwater management. A porous asphalt pavement differs from traditional asphalt pavement designs in that the structure permits fluids to pass freely through it, reducing or controlling the amount of run-off from the surrounding area. By allowing precipitation and run-off to flow through the structure, this pavement type functions as an additional stormwater management technique. The overall benefits of porous asphalt pavements may include both environmental and safety benefits including: improved stormwater management, improved skid resistance, reduction of spray to drivers and pedestrians, as well as a potential for noise reduction. With increasing environmental awareness and an evolving paradigm shift in stormwater management techniques, this research aims to provide guidance for engineers, contractors, and government agencies on the design of porous asphalt pavement structures in cold climate applications. The objectives of this study were to evaluate several laboratory porous asphalt mix designs for durability and strength in cold climate conditions. Performance tests were conducted on laboratory porous asphalt samples including: draindown susceptibility, moisture-induced damage susceptibility, dynamic modulus, and permeability testing. Based on the preliminary laboratory results and recommended asphalt cold climate mix design initial pavement design guidelines were provided based on preliminary findings and hydrological analysis.
