Implementation of the New AASHTO Pavement Design Procedure in Louisiana
The study was undertaken to provide the LA DOTD with an implementation package to facilitate adoption of the new AASHTO Guide for Design of Pavement Structures. The study included evaluation of design parameters for rigid and flexible pavements, including several new parameters such as design reliability, resilient modulus, drainage, and use of tied concrete shoulders and widened lanes. Recommendations were made for design values which best represent Louisiana conditions, materials, and construction procedures. An automated procedure was developed to estimate roadbed resilient modulus by using soils engineering and classification data as an interim design measure. Traffic equivalence factors were updated using Weigh-in-Motion data for selected vehicle types. Layer structural coefficients were updated for flexible design to reflect new materials and construction procedures. A computer program was developed for DOTD use which is tailored to its design reporting format and which has storage capabilities for pavement management purposes.
