Summary
Join us for an enlightening webcast where we will explore a groundbreaking study on the reinforcing effects of carbon-fiber grids in flexible pavement overlays. For the study, a full-scale flexible pavement structure was constructed, then divided into unreinforced and reinforced sections, both overlaid with the same asphalt mix. After conducting an accelerated pavement test (APT), the team recorded and analyzed reflective cracking, surface deformation, deflections, and moduli in the two sections. The study revealed that the reinforced asphalt overlay significantly delayed reflective cracking by a factor of 4 and reduced pavement deformation by 54% compared to the unreinforced overlay.
