Development of a Three-Dimensional Laser Scanning Prototype for Pavement Preservation Applications
The connection between the pavement friction and surface macro- and micro-texture makes pavement texture a vital topic for highway agencies and state Departments of Transportation to address. Accordingly, measuring surface texture is of prime importance in pavement preservation applications. Currently, most highway agencies rely on subjective measuring methods of pavement texture that are not reliable. With the recent advancements in laser technologies, highway agencies are gearing towards employing such developments that could potentially contribute towards better pavement surface texture characterization. With better surface texture characterization, they can better assess, monitor, and improve the pavement texture to provide better skid resistance for their highway network with the aim of ensuring safer roads for the public. This report proposes a laser scanning prototype for the characterization of the micro- and macro-texture of road surfaces. This prototype system has the advantage of capturing 3D data on pavement surfaces using an automatic, simple, and quick operation. This prototype is able to work in laboratory and in field. The development stages of this prototype are provided in this report. In addition, this report discusses different applications of the prototype created. The findings of this research are provided in three parts. Part I involves the feasibility of the prototype in characterizing the micro-texture of aggregates. Part II involves developing an algorithm to measure the mean texture depth of pavement surfaces. Part III involves finding the connection between the pavement friction and texture. Other applications of this prototype are in chip seal design. The results study and findings regarding the chip seal design are provided in the appendix.
