Workshop Overview

workshop overview graphicCharacterization of asphalt binders in practice is largely limited to developing specifications based on empirical tests that allow the user to select the appropriate binder for a given environmental condition.

In the last 15 years, there has been an increased emphasis on the development and use of a performance-based approach to select asphalt binders for use in mixtures subjected to a variety of different loading and environmental conditions. Consequently, the characterization of asphalt binders has evolved to incorporate test methods and models that address various dimensions pertaining to mixture properties and performance. Understanding the damage evolution and mechanical response of asphalt binders has also been increasingly recognized as an important first step to fully characterize the mechanical response and long-term performance of asphalt mixtures. The interactions between binder and fillers or fine aggregates make it equally important to investigate the mastic phase in asphalt mixtures.

This international 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 bitumen and mastics. The workshop will also facilitate the development of a vision and needs statement for the technical committee and future research in this area.

Summary
16 State of the art, vision for modeling efforts, and concluding discussion Round Table Discussion

Workshop Format

There will be a 45 minute time slot devoted to each topic. This includes about 25 minutes for presentation on state of the art on the topic followed by a 20-minute discussion. The last presentation will be two hours and will include time for brainstorming and developing agenda for future discussions.

Proceedings

The proceedings will be distributed to the participants in the form of a CD or made available for download after the workshop. The proceedings will include presentations in PDF format, an abstract for each presentation, and a bibliography of readily available references in each topical area. The bibliography will be developed based on inputs from the presenters and participants during the workshop.

Location

MadisonUniversity of Wisconsin–Madison will be hosting this event. Madison is a medium size city surrounded by 3 beautiful lakes and a lot of green areas.

Madison’s airport has frequent flights to major hubs like Chicago, Detroit, Minneapolis, New York, and other cities and is only 15 minutes by car from campus. Madison has a very vibrant downtown that is extremely safe and very diverse in authentic restaurants. Join us to taste Wisconsin beer and cheeses.
