Reliability of optimal intervals for pavement strength data collection at the network level
Piyatrapoomi, Noppadol, Kumar, Arun, & Weligamage, Justin (2004) Reliability of optimal intervals for pavement strength data collection at the network level. In The 6th International Conference on Managing Pavements, 19-24 October, Brisbane, Australia.
In road asset management, knowledge of current condition and understanding of deterioration rates of
pavement strength is essential input parameter for estimating fund allocations for maintenance and
rehabilitation work. However, the cost of collecting data on road pavement strength is relatively high. In a
previous pilot study, a procedure was developed for optimising longitudinal sampling intervals for collection
of pavement strength data for use in network level of road asset management for the State of Queensland,
Australia. The findings indicated that pavement strength data could be collected at 1000-meter intervals
rather than at 200-meter intervals for a tropical region of northeast Queensland, Australia. This paper
presents the results of the continuing research to assess the reliability of the usage of the 1000-metre
interval pavement strength data in predicting budget estimates for road maintenance and rehabilitation at the
In the reliability assessment, the 95th percentile budget estimates were compared with the budget estimates
calculated from 1000-metre interval pavement strength data. The results indicated that the differences
between the 95th percentile budget estimates and the budgets estimated from the 1000-metre interval
pavement strength data were less than four per cent for 10-,15-, 20- and 25-year budget estimates, and
were approximately 12.25 per cent for 5-year periods.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
