Construction data for each section can be viewed by positioning your mouse over the section in question and left-clicking.  Be sure and page-down to see all the data for multi-layered sections.  The entire buildup is shown in structural sections, but only the upper (research) mixes are shown in sections with perpetual foundations.

Reconstruction of the 2009 experiment was completed in August of 2009 by East Alabama Paving, who was selected as the contractor via a competitive bidding process.  The fourth research cycle again consists of extended traffic sections, new mix performance sections, and instrumented structural sections.  The instrumented structural sections are part of a larger, multi-state validation effort for mechanistic-empirical and perpetual pavement design.  Another 10 million ESALs is planned to be completed by the fall of 2011.
