| Abstract | Highway agencies spend a large amount of budget in collecting the pavement condition data. Visual inspection is a time-consuming and expensive task. Most agencies sample the inspection areas and use the selected sample size to represent the condition of the entire area. Decreasing the number of sample size can reduce the total inspection cost and time, but it may jeopardize the overall data quality. Reliability can be defined as a probability of a non-failure over the specific time. The reliability of the pavement plays an important role in the life cycle cost analysis. It can be viewed as the subset of the pavement quality that satisfies the users' requirement and can be used to determine the expected service life of the pavement as well. This main objective of this research is to apply the reliability theory to determine the optimal pavement inspection intervals and the appropriate sample size for pavement inspection. The relationship between reliability values and the number of sample units is investigated. The analysis used in this study is based on the relationship between the number of sample units and their reliability values. Traffic volumes are grouped to investigate the sensitivity of different parameters on the reliability values. This paper presented the optimal pavement inspection intervals determined based on the developed reliability values and the appropriate inspection sample size for highway agencies to balance between data quality issue and inspection cost control |
