• Abstract:
  There is a need to be able to quickly test materials and mixtures in-place, under real traffic. ; There have been many developments during the last few years that need verification prior to ; adopting. One such development is the new proposed mechanistic pavement design procedure. ; Another is the development of proposed performance tests that need verification. It will take at ; least 15 to 20 years to verify these procedures on existing highways. However, accelerated ; loading facilities such as the National Center for Asphalt Technology (NCAT) Test Track can ; accomplish these verification studies safely in two to three years. This can be done at reduced ; cost and without adversely affecting the driving public. ; The NCAT test track was built in 2000 and has now been in use for five years. Experimental ; sections on the 1.7 mile Pavement Test Track are cooperatively funded by a number of state DOTs ; and the Federal Highway Administration (FHWA), with operation and research managed by NCAT. ; State DOTs that have sponsored work at the track include: Alabama, Florida, Georgia, Indiana, ; Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, and Tennessee. In 2000, forty-six ; different test sections were installed at the facility, each at a length of 200 feet. Materials used ; locally by the section sponsors were transported to NCAT during construction to maximize the ; applicability of results to the sponsors. In 2003, many of these sections were rebuilt and traffic again initiated.
