Abstract

this research emphasis on using laser scan technology with high positional accuracy and high density automation for modeling the road surface.
Surface modeling is essential for all road maintenance applications. Road flexible pavement distresses will be classified and summarized. Five major categories of flexible pavement road distresses will be considered in this study.
The study deals with issues of road surveying, the safety of surveyors, data acquisition methodology, data processing, assessment, analysis and achieved accuracy. The used methodology in this paper allows accurate determination of paving material volumes that should be milled off the upper layer of the road surface and the volume of the filling material required to achieve a smooth road surface.
However, the present work shows that using terrestrial laser scanning technologies for modeling the road surface has advantages such as surveying speed, big roads, highways and tunnels. Also it provides the safety for surveyors and the absence of a disruption to traffic.
