This Road Note gives guidance on road pavement evaluation procedures suitable for bituminous-surfaced roads in tropical and sub-tropical climates and reviews alternative methods of maintenance and repair. It is intended primarily for highway engineers who are responsible for maintaining roads in these environments, but the techniques and principles on which it is based are equally applicable elsewhere.
