• 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.
