Abstract:
Porous asphalt pavements are an increasingly popular approach for introducing more sustainability and into projects and lessening their environmental impact. Currently, the design of porous asphalt pavements is based primarily on hydrologic considerations—i.e., providing sufficient storage capacity for the gradual release of captured storm water into the environment. Porous asphalt is typically used for parking lot and other low volume road applications, and as a consequence not much attention has been paid to their structural design aspects. However, even parking lot and low volume residential pavements see periodic heavy truck (e.g., for deliveries, trash removal) and bus traffic. A design procedure and representative material structural properties are required to ensure that porous pavements do not deteriorate excessively under these traffic loads.
Study Objective:
Develop a simple, easy to apply design procedure for the structural design of porous asphalt pavements.
Tasks:
1. Conduct Literature Review
2. Examine PaveNet
3. Evaluate Existing Design Methods
4. Develop Structural Properties
5. Develop Catalog Designs
6. Develop Implementation Materials
7. Prepare Final Report and Design Manual
