Vice President Raymond Robertson, Chief Executive Officer Don Collins and eight members of WRI’s Transportation Technology Business Unit joined approximately 10,000 policy makers, administrators, researchers, and government and industry representatives at the 88th Annual Meeting of the Transportation Research Board in Washington, D.C. January 11 through 15.
The Transportation Research Board (TRB) is a division of the National Research Council, which serves as an independent advisor to the federal government on scientific and technical questions of national importance. The TRB Annual Meeting addresses all aspects and modes of transportation and is the country’s largest transportation convention.
Transportation researchers also met in a variety of settings to steer the course of future research. WRI Lead Scientist Mike Harnsberger, participated as a member of TRB Committee AFK-20, Characteristics of Bituminous Materials, which is assessing the research needed to enhance performance characteristics of bituminous materials that affect long-term highway performance. Shin-Che Huang, WRI Lead Engineer, met as a member of Committee AFK30, Characteristics of Nonbituminous Components of Bituminous Paving Mixtures. This committee looks at how the physical and chemical properties of aggregates, additives and other non-asphalt materials contribute to the performance of asphalt pavements over time.
On January 15, representatives from WRI’s Transportation Technology Business Unit conducted a half-day review of WRI’s work on the Federal Highway Administration contracts “Fundamental Properties of Asphalts and Modified Asphalts, III” and “Asphalt Research Consortium.” Besides the WRI team and members of the Asphalt Research Consortium, the event was attended by representatives of FHWA, the aggregate industry, the refining industry, additives producers, state departments of transportation, and universities.
On January 16, members of the international Delft Consortium led by the Delft University of Technology (TU Delft) at Delft, The Netherlands, met to review planned activities related to the development of chemomechanics (a new area of science) to advance understanding of cracking and healing in asphalt binder.
