Kansas DOT Sets Up Certification Program in Superpave Mix Design Procedures

The Kansas Department of Transportation (DOT) has set up what may be the first combined certification program for Superpave mix design and quality control/quality assurance (QC/QA) procedures. The certification program was developed as part of Kansas DOT's plans to implement the Superpave system and QC/QA procedures by 1999.

New SHRP Online Discussion Groups Up and Running

The Superpave System: On Track, and On Schedule

Several years ago, the Asphalt Technical Working Group (TWG) challenged States and industry to implement the Superpave binder specification by 1997 and the volumetric mix design procedures by 2000. It was an aggressive schedule; after all, the Superpave specifications and procedures necessitated massive changes in the way States and industry did business. Asphalt suppliers would have to modify the way they tested and graded binders, highway agencies would have to rewrite their purchase specifications, engineers and technicians would have to become proficient in new devices and test methods, and contractors would have to learn how to deal with this unconventional mix design.

Texas Holds LTPP Pep Rally

The Texas Department of Transportation (DOT) has a Texas-size commitment to the long-term pavement performance (LTPP) program, as evidenced by 90 general pavement studies sections and 142 specific pavement studies sections located on roads throughout the State. But over the years, as new people joined the staff and others retired, the staff's understanding of the test sections and their importance waned. To bring everyone up to speed, Texas DOT recently held a 2-day LTPP "Pep Rally" in Austin.
