G'Day Rasika,The IPWEA have developed a document that might suit your needs mate. Check out their Practice Note 9. PN09: Road Pavement (Visual Assessment). There is a cost involved but worth your while to check it out rather than reinvent the wheel. These practice notes are excellent and we make use of several of them in our business when we want to implement best practice.
Thank you very much Charlette.
Much appreciated !
