Task 49, FY 1992, "Follow up on U.S.A. Asphalt Study Tour of Europe." In September 1990, individuals representing FHWA, NAPA, AASHTO, SHRP, TRB, and TAI visited six European countries to look at asphalt paving practices and results. The members of the study group in general were favorably impressed with certain aspects pertaining to asphalt pavements, and indicated an interest in investigating how these aspects could appropriately be implemented in the U.S. This task was established to assist, as required, with appropriate investigation and implementation of concepts, where warranted. Work on this task and the research conducted under NCHRP Project 4-18, "Design and Evaluation of Large Stone Mixtures," the work done on stone mastic asphalt by several states, and the TRB Task Force A2T51 on Innovative Contracting Practices was coordinated. A meeting was held during the 1991 TRB week, at which plans to construct a few test sections of SMA were discussed. Byron Lord is coordinating the FHWA efforts in this area. Funding was used for travel expenses for an engineer from the Colorado DOT to travel to the LCPC facility near Nantes, France, for on-site inspection and training in connection with the asphalt testing equipment that is being purchased. A report on the equipment was received and circulated to all members of the AASHTO Highway Subcommittee on Materials.
