To emphasize the partnership involved in implementing the Superpave system, FHWA recently introduced a new Superpave logo. The logo shows the principal partners in the Superpave implementation program--namely, the American Association of State Highway and Transportation Officials, the highway industry, and FHWA. "Superpave 2000" signifies the target date for nationwide implementation of the Superpave volumetric mix design procedures.
Two of the SHRP showcase workshops have new project managers. Patrick Bauer now serves as project manager for the showcase on innovative pavement maintenance materials. He can be reached at 202-366-1554 (fax: 202-366-9981). Michael Smith is the new project manager for the preventive maintenance treatments showcase. Smith can be reached at 202-366-4057 (fax: 202-366-9981).
Both Bauer and Smith are with FHWA's Pavement Division.
The Asphalt Institute has recently released the second in its series of Superpave manuals. The manual, Superpave Level 1 Mix Design, describes the volumetric mix design procedures in detail and
provides an overview of the performance prediction procedures. Topics covered include the asphalt and aggregate material selection procedures, asphalt mixture volumetrics, volumetric mix design,
and Superpave gyratory compactor procedures. A detailed example of a Superpave volumetric mix design is also included. The 130-page report is available from the Asphalt Institute (telephone: 606-288-4960; fax: 606-288-4999).
