A common manifestation of moisture-induced damage in asphalt mixtures is the loss of adhesion at the aggregate–asphalt mastic interface and/or cohesion within the bulk mastic. This paper investigates the effects of moisture on the aggregate–mastic in... Read More about Moisture-induced strength degradation of aggregate-asphalt mastic bonds.

Mechanical and structural assessment of laboratory- and field-compacted asphalt mixtures (2014)
Journal Article
