Background
In 2018, a total of six SPS-2 Preservation Tech Day Events were scheduled throughout the country, as noted above.

At each of these events, a workshop is held to discuss the SPS-2 test sections and their performance to date; an update on current concrete preservation strategies; and a discussion of the national pooled fund experiment to piggy back onto the existing SPS-2 experiment. 

Upon conclusion of the workshop, participants review the 18 to 26 year old test sections in the field.  The original SPS-2 experiment was established to evaluate five design features: (1) Thickness: 8” & 11”, (2) Flexural Strength: 550 psi & 900 psi, (3) Travel Lane Width: 12’ & 14’, (4) Base Type: Aggregate Base, Lean Concrete Base, & Permeable Asphalt Treated Base, (4) Drainage: drained and undrained.
