Rolling Edge Test

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 the 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 a determined level. A series of measurements are taken between the underside of the beam and the pavement surface to indicate the sectional profile and the series of sectional profiles will indicate the longitudinal profile accordingly.
