The objective of this research is to present 3-dimensional texture parameters from recovered texture heights. A newly designed and constructed Portland cement concrete pavement with 13 different types of pre-textures and textures, including turf dragging, burlap dragging, tining, grinding, and grooving, was selected as the test site. The test pavement surface texture heights were recovered by the University of Manitoba using photometric stereo technique. Texture was also measured by others using various methods. Fiction and noise were measured by other researchers as well. A comparative study is conducted between computed 3-dimensional texture parameters and other established texture measurements e.g. the Circular Track Meter, the Dynamic Friction Tester, and high-speed texture profiler. Statistical analyses of texture parameters and frictionoise data are conducted to assess the performance of the various textures and to find correlation between texture and frictionoise characteristics. It is found that 3-dimensional texture parameters obtained from imaging are strongly correlated to other established texture measurements, and to pavement friction and sound intensity noise. By using the combination of the computed 3-dimensional parameters, it is possible to have a better understanding of the distribution of the surface texture and its predicted pavement performances.
