What is it about?
Coastal roads are at risk for pavement damage and increased maintenance and repair costs as groundwater rises with sea-level rise. This paper examines the performance and adaptation costs associated with various pavement structures for future projected groundwater levels at two case-study sites in coastal New Hampshire.

Why is it important?
This investigation shows that pavement base-layer modifications can mitigate service-life reduction projected with 1.0 foot of sea-level rise and can delay pavement inundation. This is important for pavement design and rehabilitation in coastal regions where current pavement designs may no longer achieve their design life.
Perspectives
The Infrastructure and Climate Network (ICNet) at the University of New Hampshire brings people together from many disciplines: engineering, climate science, hydrology, social science, etc. to discuss climate change and infrastructure. Climate is changing and practicing pavement engineers are looking for guidance in determining future environmental conditions for use in pavement design. The motivation for this paper and a previous paper: "Assessing the effects of rising groundwater from sea-level rise on the service life of pavements in coastal road infrastructure" came from these discussions.
