8,851,996 ESALs on the Track as of 2300 hours on September 14, 2017 (89% of the 10,000,000 ESAL goal).  Rut depths, roughness, and macrotexture are measured every week.  Detailed construction and performance information for each section can be reviewed by clicking the links shown near the top of this page.  The web interface is an ongoing effort.  Please check back often!

GOD BLESS AMERICA !

Performance data for each section will soon be available for viewing by positioning your mouse over the section in question and left-clicking.  Based on feedback from our research sponsors, the performance reports have been revised to include crack maps.   The 2012 performance reports will be a fully integrated and active part of the web presentation. 

2012 Track with Lee Road 159

Every Monday, trucking is suspended so that vehicle maintenance can be performed and pavement performance can be quantified.  An inertial profiler equipped with a full lane width dual scanning laser "rutbar" is run weekly around the entire Track in order to determine individual wheelpath roughness, right wheelpath macrotexture and individual wheelpath rutting for every experimental section.  Additionally, 3 random locations were selected within each section in a stratified manner to serve as the fixed test location for nondestructive wheelpath densities.  Transverse profiles are measured along these same locations each week so that rutting may be calculated using a contact method.  Every month, wet ribbed surface friction testing, falling weight deflectometer testing, and structural high speed response data is collected, along with videologging to provide a permanent visual record of surface performance.  Every quarter, cores are cut from the wheelpath of every section so that densification of each layer can be considered.
To facilitate lab to field performance correlations, numerous test specimens were compacted using actual plant run material at the time test sections were constructed.   Additionally, hundreds of pounds of loose mix were sampled and saved during production of each experimental section to facilitate other research projects that can be enhanced by being plugged into Track research.
