Abstract:The objective of this task is to develop the concept and framework for a procedure to routinely create, re-calibrate, and update the
Trigger Tables and Performance Models. The scope of work for Task 6 includes a limited review of the recent pavement
management systems literature for key elements for inclusion, strategies and procedures used to ‘update’ pavement performance
(deterioration) models, and triggers for initiating a treatment evaluation. Because this is a relatively new process, the task entailed
contacting and surveying several state DOTs that already have an updating process in place. The task included interaction with
MoDOT personnel in order to be sure that the proposed framework for the re-calibration procedure can be incorporated into what
MoDOT already does to update triggers and performance models and is compatible with current MoDOT practices. It is incumbent
upon MoDOT personnel to adapt and implement the re-calibration framework in order to continue to realize the full potential of
the modified pavement management process.
