This article describes a pavement roughness detection system that can be used to test the flatness of the construction phase (before the concrete to harden) cement concrete pavement. The test system is based on optical triangulation principle, by the laser projector and a CCD image sensor camera composition, using a structured light technique for three-dimensional visual measurements. The system can plastic cement concrete pavement flatness detection directly help improve the flatness of the cement concrete pavement.
