In 1996, MoDOT began reviewing a proposal to use diamond grinding as a means to provide texture and a smooth profile in place of a transversely tined finish on newly constructed Portland cement concrete pavement (PCCP). Research suggests the smoother a pavement is initially; the better it will perform over time and the longer it will last. Diamond grinding can lower the profile index by 50% or more on newly constructed pavement and could produce a very smooth ride. Two projects have been completed in Missouri that are currently being evaluated. Data collected for this evaluation consists of visual distress surveys, profilograph measurements, Automated Road Analyzer data (ARAN), Falling Weight Deflectometer data (FWD), and friction testing. The surveys and tests are performed on a yearly basis.
This investigation is part of the Cold Regions Research and Engineering Laboratory's (CRREL) on-going characterization of pavement performance in seas...
This report presents the results of a study of pavement deflections. The study covered all level E falling weight deflectometer (FWD) deflections and ...
