Fundamental Properties of Asphalts and Modified Asphalts, III

TASK 1. COORDINATION
The goals of this task are to maintain contact with current State-of-the-Art and State-of-the-
Science in fundamental research on asphalts and modified asphalts, to keep abreast of current
and on-going science and technology in asphalt research, and to learn the needs of the asphalt
technical community.
During this quarter, WRI hosted a four-day RHEOBIT asphalt rheology course taught by Dr.
Geoffrey Rowe and Dr. David Anderson. Course topics ranged from basic asphalt properties to
master curve principles and from basic testing techniques to sources of measurement error.
Hands-on sessions were conducted with spreadsheets and RHEA analysis software, and with
laboratory instrumentation.
During this quarter, WRI welcomed a two-day visit with Dr. Ernest Bastian and Dr. Terry
Arnold, both of FHWA and co-COTRs for the Fundamental Properties of Asphalts and Modified
Asphalts contract with WRI. Ongoing research was discussed with individual researchers and
the project status was discussed with Ray Robertson, Fred Turner, and Mike Harnsberger, WRI.
Next quarter WRI will host the 2008 Petersen Asphalt Research Conference (July 14-16) and the
Pavement Performance Prediction (P3) Symposium (July 16-18). Details can be obtained at
