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 and/or multi-part 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 2015 experiment was completed in September of 2015 by East Alabama Paving, who was selected as the contractor via a competitive bidding process.  The sixth research cycle again consists of extended traffic sections, new mix performance sections, instrumented structural sections, and pavement preservation (on the Track, on Lee Road 159, and on US-280).  The new (2015) instrumented structural sections are part of a larger, multi-state validation effort to identify laboratory tests that predict surface cracking in the field.  Another 10 million ESALs is planned to be completed by the fall of 2017.
