Abstract:
A research study was initiated by the Louisiana Department of Transportation and Development (LADOTD) in conjunction with the

Federal Highway Administration (FHWA) to evaluate the overall performance and eff ectiveness of LADOTD’s Pavement Management

System (PMS). The study was divided into two phases. The fi rst phase focused on the assessment of the state-of-the-practice of

LADOTD’s PMS regarding accessibility, PMS reports, reference location systems, and distress indices. Part of the assessment was

conducted through the analysis of the responses of all district engineers to specially designed survey questionnaires and personnel

interviews. The details of fi rst phase of the study can be found in the LTRC Report No. 430. This report (LTRC Report No. 460) focuses

on the second phase of the study, which includes a review and update of both pavement performance and treatment models. During

the second phase, a comprehensive evaluation and analysis of the pavement performance and treatment models were conducted

using LADOTD pavement distress data and historical data. Statistical analyses were used to generate the model for pavement

condition prediction and treatment performance evaluation. It should be noted that most existing LADOTD pavement performance

models were developed using the initial few years of distress data, which tends to either underpredict or overpredict the pavement

condition. Pavement performance models based on the available 10 years were developed to

enhance the predicting capabilities of LADOTD’s PMS section.
