Ultra-Thin Whitetopping Short Courses
The ICT conducted research to assist IDOT with optimal design and construction strategies for its UTW projects. As part of this research project, ICT developed guidelines for UTW projects that address thickness, concrete material selection, and construction practices.
Specifically, ICT researchers evaluated the effects of structural macro-fibers and concrete material properties on slab size and thickness requirements for UTW rehabilitation. Other factors evaluated included the existing condition of the HMA, HMA thickness, interface preparation and strength, and saw-cut timing and depth.
IDOT uses the new guidelines to improve the efficiency and quality of the design and construction for UTW projects. The expected end results include increased maintenance intervals, extended pavement life, and reduced travel delays.
