Second International Workshop on Asphalt Mastics

Workshop Overview


Currently, performance-based specifications are not available for the selection of asphalt mastics (i.e., mineral filler + asphalt binder). In the past, mechanical properties of mastics were obtained based on over-simplified models.

In the past years, it has been recognized the importance of mastic characterization on the performance of the asphalt mixtures subjected to a variety of loading and environmental conditions. Recently, the characterization of asphalt mastics has moved into incorporating test methods that address non-linearity and damage evolution. Understanding the mechanical and chemical interactions between asphalt binder and fillers and consequently the response of asphalt mastics to a variety of loading conditions has been recognized as an important step to fully characterize the long-term performance of asphalt mixtures.

This second workshop is being organized by the Working Group 07 on Bitumen and Mastics of the Technical Committee on Constitutive Modeling of the International Society for Asphalt Pavements (ISAP). The main objective of this workshop is to serve as a platform for exchange of information on the state-of-art in various aspects of modeling and characterization of asphalt mastics. The workshop will also facilitate further development of a vision and needs statement for the technical committee and future research in this area.
