1,713,861 ESALs as of 2300 hours on March 28, 2007 (17% of the 10,000,000 ESAL goal !).

RUTTING is being measured weekly from transverse profiles using the 6-point virtual "bent wire" method, averaging 2.1 mm on 1/3/07.

ROUGHNESS (via inertial profiler) within the middle 150 ft (research) portion of each section averaged 79 inches per mile on 1/19/07.

GOD BLESS AMERICA !

Reconstruction plans for each section are viewable by positioning your mouse over the section in question and left-clicking.  Black sections will remain in place, red sections will be mill and inlay, and blue sections will be deep structural replacements.  If you don't already have Adobe Reader® to view this information, you can download it now for free.

Funding for the initial construction in 2000 of the 1.7-mile oval facility, which has been built on 309 acres of land purchased by Auburn University, was provided by the Alabama Department of Transportation (ALDOT).  Geometric design of the roadway and architectural design of the onsite facilities was handled by David Volkert and Associates, which also served as the construction engineering and inspection consultant for the ALDOT administered construction project.  The first phase of construction was competitively awarded to W.S. Newell and covered initial site work through completion of the subgrade.  The second phase was awarded to APAC’s Couch Division and involves completion of the pavement structure through the experimental mixes.  East Alabama Paving completed a significant portion of work in both contracts as a subcontractor.  A state-of-the-art, 4700 square foot onsite testing laboratory and support structures were built by W.W. Dyar.

Reconstruction activities at the Pavement Test Track were completed in September of 2003.  The 2003 experiment required milling and inlaying 14 sections with new rutting study mixes, deep removal of 8 sections to facilitate a small (instrumented) AASHO-like structural experiment, and continuing traffic on the remaining sections to extend the original 2000 experiment over a second application of design traffic (i.e., another 10 million ESALs).  The reconstruction project was again funded via a multi-state research co-op, with pooled fund management and construction contract administration provided by the Alabama Department of Transportation.   Volkert Construction Services returned to serve as the State's CEI inspection team.  When bids were opened on March 28th, East Alabama Paving was identified as the successful contractor.  Aggregate hauling began around the first of May, with milling activities for the structural experiment initiated several weeks thereafter.  Production of hot-mix asphalt for placement on the Track ran from July 14th to August 23rd.
