Review of Louisiana's Pavement Management System

Abstract

“Louisiana–Vision 2020” serves as a benchmark for improving highway pavements over a 20-year period. Cost-effective pavement preservation is emphasized in current Louisiana state law and federal law. The Louisiana Department of Transportation and Development (LADOTD) and the FHWA strategic plans also emphasize cost-effective pavement preservation. In an effort to improve the pavement management system (PMS), the Louisiana Transportation Research Center initiated a two-phase research study to evaluate the overall performance and effectiveness of the system. This paper focuses on the Phase I study and addresses the state-of-the-art practice of LADOTD's PMS and the results of a departmental survey to assess the needs of the various districts. The use of various location reference systems by different units in the department makes linking to different database sets difficult. Although many of the districts’ engineers have no concerns about all the referencing systems, most would prefer to have a unified reference location system. All the districts have access to the PMS data and most of them use it; however, the degree of use varies from one district to another. This paper also discusses the types of PMS output and reports, the degree to which the outputs are analyzed, the accuracy of the information currently available, and the degree to which the current PMS data track and differentiate between different preservation actions.

Research Implementation of AASHTOWare Pavement ME Design in Louisiana

“…The Louisiana DOTD began collecting pavement distress data by windshield survey in the early 1970s. Since 1995, the Louisiana DOTD has used the Automatic Road Analyzer to conduct network-level pavement condition surveys (10). Louisiana conducts a network-level pavement condition survey once every 2 years.…”

Revisión del sistema de gestión de pavimentos de la red ciclorrutas de Bogotá

“…Esta información facilitará la formulación de modelos de deterioro para cada una de las familias de segmentos analizados y proveerán al IDU de herramientas empíricas para la estimación de vida útil y tiempo óptimo para adelantar labores de mantenimiento (George, 2000, Khattak et al, 2008.…”

“…Such information will be useful for the development of deterioration models for each segment group under study and they will provide IDU with empirical tools for assessing life time and optimal periods to perform maintenance tasks in advance (George, 2000;Khattak et al,, 2008).…”

APCI Evaluation Method for Cement Concrete Airport Pavements in the Scope of Air Operation Safety and Air Transport Participants Life

“…This approach enables rational planning of airport pavement repairs and renovations. Many countries' experiences confirm that proper management of both airport [1] and road [2][3][4][5] infrastructure must rely on detailed and up-to-date information on the condition of a pavement's surface.…”
