This is a test conducted on site to determine the surface profile and the cross fall of the as-cast concrete pavement and is conducted by the laboratory staff . Normally the acceptance of surface profile is to be determined by the survey results and the respective sections . However in case there are some local areas that are found beyond the design profile and out of tolerance , the Rolling Edge Test will be deployed to further investigate . The test apparatus includes a long beam which to be placed transversely across the test area with determined level . A series of measurements are taken between the underside of beam and pavement surface to indicate the sectional profile and the series of sectional profiles will indicate the longitudinal profile accordingly .
