VISUAL CONDITION SURVEYS, A TOOL IN THE PLANNING OF MAINTENANCE

The paper describes the development of performance models for raveling, alligator and longitudinal cracking, and the overall pavement condition. The models were derived from visual condition surveys carried out on a number of pavement sections during a five year period. A relation is derived between the maximum Benkelman beam deflection and the condition of the pavement as determined by visual condition surveys. It is also shown how a preliminary overlay thickness estimation can be made using the described performance models, the relation between Benkelman beam deflection and visual condition, and the TRRL overlay design model.
