Performance Testing for Superpave and Structural Validation


There are many organizations and people to thank for support of this research. Most notably, the financial support through the TPF and State Planning and Research programs by the following State transportation departments: Connecticut, Florida, Iowa, Illinois, Kansas, Maryland, Michigan, Minnesota, Mississippi, Montana, North Carolina, Nebraska, Nevada, New Jersey, New York, Oregon, Pennsylvania, and Texas.

Significant credit is also given to the following private industry organizations that provided in-kind contributions: NuStar (formerly Citgo), Dow, DuPont, Road Science LLC (formerly Koch), Paramount, Butaphalt (formerly TexPar), Trifinery GCA, Trumbull, Owens Corning, Wright Asphalt, Martin Color Fi, Bit Mat, Mathy Construction/MTE Services, the National Asphalt Pavement Association, FNF Construction, Consulpav, Rubber Pavements Association, International Surfacing Systems, and Recovery Technologies Group.

A great deal of recognition must be made to FWHA staff John D’Angelo (retired), Tom Harman, Kevin Stuart (retired), and Jack Youtcheff for identifying, developing, and coordinating the experiment. In addition, the members of the FWHA Asphalt ETGs and their associated State transportation department and private industry friends and members are acknowledged for their input on the experiment’s development.

ALF construction and many FWD tests could not have completed without the efforts and services of FHWA Eastern Federal Lands.

FHWA MAMTL provided very valuable onsite testing during construction for quality assurance in participation with the TFHRC Bituminous Mixtures Laboratory.

The final report could not have been assembled without contributions from research support staff and associates in the ALF operations. Binder Rheology Laboratory and Bituminous Mixtures staff were Dennis Lim, Mario Tinio, Susan Needham, Scott Parobeck, Frank Davis, and Senthil Thyagarajan.
