Thirdly, the BRDF based pavement image formation model revealed that quantifiable changes in the brightness of images occurs due to pavement wear-related changes in texture depth and spacing (wavelength). The traffic induced pavement wearing process was simulated by gradual smoothening of the modeled surfaces and then images corresponding to each wearing stage were generated. The theoretically predicted variation of the image brightness due to wear was experimentally verified using images from a gradually worn out concrete specimen. Finally it was illustrated how the brightness evaluation of wheel path images has the potential to be a screening tool to monitor the degradation of macrotexture and hence the skid-resistance of pavements at the network level.
