Using bond strength and surface energy to estimate moisture resistance of asphalt-aggregate systems

Fundamental Approaches to Predict Moisture Damage in Asphalt Mixtures: State-of-the-Art Review

“…[46] In conclusion, Table 4 demonstrates that a large number of laboratory test procedures have been used to validate SFE component calculations, including binder pull-off and peeling tests, mastic cohesion strength and adhesion tests, asphalt mixture tensile tests, stiffness, dynamic modulus and fatigue tests, rolling bottle and boiling water tests. In some cases, very good relations between predicted water sensitivity levels, based on the SFE concept and measured performances were obtained, [15,20,26,[28][29][30]40,51], while in other cases relations were less good or even nonexistent as reported in [22,41,46,53,55]. It is clear that SFE parameters are important, but the overview of findings suggests that very often other properties need to be included when estimating the moisture susceptibility in laboratory tests or in practice.…”

Investigating the Effect of Various Fillers on Cohesive Failure Mechanism in Asphalt Mixtures

“…By increasing the cohesion free energy of mastic or binder, tensile strength is also increased. Of course, the following relationship exists when the occurred failure in Pull Off test is of cohesion failure type [38].…”

Investigation of moisture susceptibility of SBS modified asphalt containing Alumina Trihydrate by static contact angle measurements

“…Many theories have been developed so far to explain and evaluate the water damage mechanism [31,32]. Accordingly, one of the theories is Surface Free Energy (SFE) that is used widely and successfully to evaluate the moisture susceptibility of asphalt mixture and determine the asphalt binders' cohesive strength and adhesion strength of asphaltaggregate based on micro-mechanisms [33,34]. The purpose of this research is to investigate the moistureinduced damage potential of binders containing ATH ame retardants through the SFE method.…”
