A REVIEW OF THE TECHNICAL ANALYSIS FOR THE CANADIAN LONG TERM PAVEMENT PERFORMANCE (C-LTPP) PROJECT

This report reviews the type, quantity and quality of data being assembled under the C-LTPP program in order to ensure that this data can support the statistical and other analysis required to: (1) determine the cost-effectiveness of alternative rehabilitation methods, and (2) determine the effect of traffic, environment, soil type, etc. on pavement performance. The results of the review indicate that the C-LTPP project will fail to meet the objectives if corrective actions are not taken. In particular, the materials and pavement performance data currently being collected at all C-LTPP test sections will have to be augmented by data related to user costs in order to determine the cost-effectiveness of various rehabilitation alternatives. If the objectives of the C-LTPP program are to be met, there is a need to apply some corrective actions to the C-LTPP program. The recommended corrective actions involve: (1) collection of data required to determine user costs, and (2) the application of Bayesian statistical methods to the C-LTPP data.
