Durability of Porous Pavement Materials with Recycled Materials and Warm Mix Asphalt Technology

This project integrates three innovations in the pavement engineering field, Permeable Pavements (porous pavements), Warm Mix Asphalt (WMA), and recycled materials. Porous pavements allow water to penetrate to the underlying surfaces so that drainage collection can be enhanced. Porous asphalt pavements are designed with increased air voids in the mixture which allow water to flow through the pavement. A reduction in construction and maintenance costs of drainage structures has been reported with this type of pavement construction. Hot Mix Asphalt (HMA) has been a traditional pavement utilized in pavement construction. It is produced at a discharge temperature of between 280°F (138°C) and 320° F (160°C). This results in high energy (fuel) costs and the generation of greenhouse gases. Environmental awareness and the need for improved energy efficiency has increased rapidly over the past few years and extensive measures such as air pollution reduction targets set by the European Union under the Kyoto Protocol have encouraged efforts to reduce greenhouse gas emissions. Warm mix asphalt (WMA) is one technology in response to these efforts. WMA is produced at a lower temperature. The goal for WMA is to use existing HMA plants and specifications to produce quality dense graded mixtures at significantly lower temperatures. When compared with conventional HMA, a reduction in emissions and energy consumption has been reported. Recycled materials, including recycled asphalt pavements (RAP), waste shingles, and recycled aggregates have been widely used in traditional HMA in several states; however, the integration of these three aspects of innovations has not been widely pursued.
