Mechanistic Characterization of Asphalt Overlays for Pavement Rehabilitation and Preservation using Pavement ME Approach

The objectives of this research are to assess/evaluate the performance and condition of existing and prospective structural overlay sections utilizing Louisiana Department of Transportation and Development's (LADOTD's) locally calibrated, AASHTOWare Pavement Mechanistic-Empirical (ME) Design software; to address the existing issues regarding Pavement ME encountered by the LADOTD design engineers in their design practice, including the dysfunction of the interlayer of the flexible pavement design module, soil cement base and the excessive sensitivity of slab width of the rigid pavement design module; to evaluate the performance and existing trigger system of possible pavement preservation overlay strategies using Pavement ME Design approach; and to update local calibration factors used in an asphalt overlay design of Pavement ME and develop a set of optimum design inputs for both pavement rehabilitation and preservation asphalt overlays for the LADOTD implementation.
