| Abstract: | By studying the characteristics of the surface rou ghness differentiate d by the eye and the digital image technique, a method of evaluating and measuri ng pavement surface texture depth utilizing digital image technique was presente d. With this method, the pavement surface roughness can be recorded by an ordina ry digital camera, and the pavement texture depth can be obtained by the pixel a nalysis of recorded images. Compared with the conventional methods, the method p roposed here is simple and easy to apply. It is a promising method for evaluatin g and measuring the pavement surface performance with higher precision and lower cost. |
