The Identification, Classification and Causes of Pavement Under-Performance

The purpose of this paper is to present a study, Austroads Project AT1067, that attempted to discern the identification, classification and causes of pavement under-performance. The results cover: (1) the development of a desktop approach for estimating the linear roughness progression rate (LRPR) for identifying and classifying ‘good’, ‘fair’ and ‘poor’ performing pavements for a network performance profile; (2) use of this approach to identify ‘poor’ performance on pavement segments selected for follow up field inspection; and (3) a questionnaire survey for practitioners to rank the broad and specific causes of ‘poor’ performance of pavement segments in Queensland identified by their high estimated values of LRPR. The questionnaire survey response from the Districts found that the broad causes of under-performance, in descending order, were ranked as follows: (1) inadequate design; (2) inadequate maintenance; (3) inadequate materials; and, (4) inadequate construction. The LRPR estimation approach assesses the underlying rate of roughness deterioration using time series roughness data on individual pavement segments and accepting or rejecting individual data points by a set of data filtering rules aimed at estimating the underlying rate of the most recent deterioration.
