What is Moisture Damage in New Mexico Pavements about?

This study evaluated the permeability and moisture damage of New Mexico pavements built with Superpave mixes. Laboratory and field testing were conducted to determine permeability (k-values) and tensile strength ratios (TSR) of asphalt samples. The results showed that permeability increases exponentially with air voids. In situ k-testing produced the highest permeability values. Permeability also increased with decreasing TSR, indicating higher moisture damage. The AASHTO T283 method provided a more conserv
