TM Specifications in the U.S., Europe, and elsewhere in the world are increasingly dependent upon basic principles of rheology and the application of advanced computer techniques. An understanding of these basic principles is essential for those developing and applying specifications as well as developers and producers of new and enhanced binders and asphalt mixtures, and researchers in academia and industry. The purpose of these workshops is to introduce the basic principles of rheology as they apply to asphalt binders and mixtures, to introduce measurement principles and analytical concepts, and to provide a hands-on experience in the laboratory that is closely integrated with the classroom work. This highly interactive workshop is intended for engineers and scientists experienced with asphalt binders but seeking fundamental knowledge that is not available elsewhere. Workshop registration is limited to no more than 15 participants per session. The principal instructors for the workshop are Drs. David A. Anderson and Geoffrey Rowe. Dr. Anderson, formally principal investigator for the Strategic Highway Research Program - project on Asphalt Binder Physical Tests, has a long history of working with many aspects of asphalt binders. Dr. Rowe, president of Abatech, has a wide range of experience and has been responsible for the development of a suite of software programs for rheological analysis of asphaltic materials.
