Construction Data

Current Test Cycle

The first practice mix for the 2015 reconstruction effort was produced on July 13, 2015. The last sublot was placed on the Test Track on September 1, 2015 by East Alabama Paving, who was selected as the contractor via a competitive bidding process. The last sublot was placed on US-280 on September 14, 2015. Fleet operations began for the sixth Test Track research cycle on October 8, 2015 after baseline data collection was complete.

The sixth research cycle consists of extended traffic sections, new mix performance sections, instrumented structural sections, and pavement preservation on the Test Track, 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 fall 2017.

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