Application of Surface Energy Measurements to Evaluate Moisture Susceptibility of Asphalt and Aggregates
Moisture damage in asphalt mixtures can occur within the asphalt mastic (cohesive fracture) or at the aggregatemastic interface (adhesive fracture or failure). Whether or not a cohesive or adhesive failure occurs depends on the nature of the mastic and the relative thickness of the mastic. The majority of previous studies on this subject focused on the development of mixture tests and empirical parameters to quantify moisture sensitivity of asphalt mixtures. This project was conducted to attain fundamental understanding of the moisture damage process by carefully considering the mechanisms that influence durability of the adhesive interface between aggregate and asphalt and the cohesive strength and durability of the mastic.
