Abstract
The continued rise of global sea levels has been attributed to climate change. Effects of Sea Level Rise (SLR) include shoreline erosion, wetland loss, amplified storm surges, increased nuisance flooding, permanent inundation, saltwater intrusion into aquifers, rising groundwater table, and increased intensity of tropical cyclones. The combination of extreme precipitation events (i.e., tropical cyclones) and the effects of SLR impacts the amount and frequency of saturation and inundation of coastal pavement infrastructure. Coastal pavements are not necessarily designed for extreme excess moisture situations. Moisture content can impact the resilient modulus of pavement base course and subgrade layers. Given its influence on the postinundation resilient moduli of the coastal pavement and base course and subgrade layers, it is important for transportation management personnel to understand their post-inundation moisture states for short-term and long-term planning. This study employed two different types of dielectric soil moisture sensors, and vibrating wire piezometers were installed in pavement base course and soil subgrade at four locations along Alabama Highway 180 (AL-180), a coastal highway experiencing SLR, in an effort to understand the fluctuations in volumetric water content (.), bulk electrical conductivity (sb), and groundwater levels at these locations due to SLR. This paper presents the sensor installation procedures and the data collected thus far. The data will be used to evaluate the effect SLR is having on pavement performance in coastal Alabama.
