Abstract: By studying the characteristics of the surface roughness differentiated by the eye and the digital image technique‚a method of evaluating and measuring pavement surface texture depth utilizing digital image technique was presented.With this method‚the pavement surface roughness can be recorded by an ordinary digital camera‚and the pavement texture depth can be obtained by the pixel analysis of recorded images.Compared with the conventional methods‚the method proposed here is simple and easy to apply.It is a promising method for evaluating and measuring the pavement surface performance with higher precision and lower cost.

Key words: asphalt pavement, texture depth, digital image technique
