Applications of Terrestrial Laser Scanner in Detecting Pavement Surface Defects

An entire roadway system represents a crucial element in the sustainable urban transportation planning process. Pavement surfaces are at continual risk of accumulating serious deteriorations and defects throughout their service life due to traffic loading environmental impact. Since networks growing rapidly, relying on visual pavement inspection is not always feasible. Therefore, this paper proposes an effective assessment method for evaluating flexible surface distresses using terrestrial laser scanner (TLS) calculating condition index (PCI). The proposed results road assessments becoming faster, safer, more systematic. It also aims determine geometric characteristics investigated roads. A major Egypt was selected test technique compare it with traditional method. evaluation carried out assess different types distress, such as cracking, rutting, potholes, raveling distresses. Every distress defined terms area, width crack, intensity, data from TLS were then processed by MAGNET COLLAGE software. MATLAB program developed match observational plane equations. PAVER software used PCI values each position. revealed observations reveal significant improvement determining characteristics.
