ABSTRACT
Sustainability and cost effectiveness in infrastructure development have received significant attention in recent years. The California Department of Transportation (Caltrans) is interested in the development of fully permeable pavement designs for use in areas that carry heavy truck traffic as a potential stormwater management Best Management Practice (BMP) to provide low-impact infrastructure and efficient system operation. Fully permeable pavement is a contemporary design approach in which each layer of the pavement is permeable and stores water, thereby avoiding the adverse effects of stormwater on pavement users. An innovative design methodology was developed based on a mechanistic-empirical design approach by University of California Pavement Research Center (UCPRC). To validate and calibrate the newly developed design method, two test sections comprised of fully permeable asphalt and concrete pavements were constructed at California State University, Long Beach (CSULB). Test sections showed reliable performance in terms of pavement distresses after 14 months of traffic. The collected data from the strain gages and pressure cells revealed that the asphalt section has experienced more stress and strain in comparison to the concrete section. The collected data will be used to validate and calibrate the pavement structural design procedure.
