DISTRESS PERFORMANCE RELATIONSHIPS FOR FLEXIBLE PAVEMENTS

In the research described pavement condition and serviceability data from a number of sources were examined and distress/performance relationships investigated. It was found that rut depths less than 0.2in have no effect of serviceability. It is suggested that due to problems encountered with data examined in this work, interactive or indirect performance modelling techniques are more suitable than standard approaches to performance modelling. Pavement management requires that comparison be made between alternative plans of action to determine the most appropriate strategy for designing, maintaining and rehabilitating a pavement section or network. If several factors are to be involved in this comparison of strategies, then a method of combining these factors into a single performance indicator is required. Three methods of achieving such a combined index are discussed: deduct values; utility theory; and, unique sums. Advantages of each technique are noted and examples of their use are provided. (TRRL)
