Abstract

Pavement design procedures heavily rely on historical climate. This practice can be a threat to the pavement infrastructure predominantly because of anthropogenic climate change. Therefore, there is a necessity to consider the climate change parameters in pavement design. This study quantifies the influence of climate change on pavement performance in New Jersey. In addition, this study also explores various modified asphalt mixtures to mitigate the climate change impact on asphalt and composite pavements. The scope of this work is carried out in four phases, which include data collection, laboratory material testing for both conventional and modified asphalt materials, pavement performance prediction using pavement mechanistic-empirical design, and selection of optimal modified asphalt materials to mitigate the climate change impacts. To achieve this, two pavement sections are considered in New Jersey. The pavement material, design, and traffic data were collected from the New Jersey Department of Transportation. In addition, statistically downscaled climate change models were gathered from Coupled Model Intercomparison Project (CMIP) GFDL-EMS2g.1, which was processed by the US Department of Transportation CMIP Data Processing Tool. This study concludes that increased temperature caused by climate change results in high pavement deformation in the asphalt concrete layer. Using modified asphalt mixtures can be an alternative to mitigate the climate change impact in New Jersey.
