26 / PCC grinding certification and evaluation
(Contractor certification process for concrete grinding; real-time smoothness monitoring during grinding operations behind grinder, monitor result to provide QC feedback loop)
27 / PCC curing methods
(Better tools are needed to provide and evaluate curing effectiveness; primarily driven by flatwork issues; optimal timing of curing, utilize sensors to monitor moisture loss).
MN – optimal timing of curing - do on a sidewalk and test timing of curing issues +/-30 minutes / MN-3
28 / PCC pavement joint seals
(Evaluate design, materials, and practices for joint sealants; expand on work done to date; which combination of factors provides best performance and LCC).

(Applications and performance on low volume roadways, city streets).
30 / Sustainable Practices for Concrete Pavement
(Examine potential for increased usage of recycled aggregate in concrete. Design and construct test sections utilizing recycled concrete from in place sections. Include existing studies and examine for the three sustainability objectives: Environmental, Economic and Performance). / IL
MN-5
31 / Sustainable preservation of thin concrete pavements and overlays
(With the growing prevalence of thinner concrete pavement solutions, particularly concrete overlays, there is a need for techniques to preserve and extend their service life. Develop tools for the life extension of thin concrete pavements including UBOL and BCOAs. Utilize test sections with cracking, broken panels, and heaving. Create artificial distresses on the panels. Include precast repairs, fiber reinforcement and epoxy, etc. Perform optimal repairs and monitor seasonal performance. Perform life cycle cost analysis or ROI based on early performance).
32 / Sustainable solutions to joint deterioration
(Permeable base sections, while drainable, are problematic from construction and performance standpoints. Stable base configurations with enhanced drainage are needed. Construct test cells with both conventional dense-graded, non-drainable bases as well as innovative materials such as shredded tires as wick drains, recycled aggregates, etc.) / MN-1
