• 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.
