Pavement Loading User Guide (LTPP-PLUG)
LTPP Pavement Loading User Guide (LTPP PLUG) is a stand-alone guide and database software application that provides guidance for development of axle loading defaults and selection of the defaults for Mechanical-Empirical Pavement Design Guide (MEPDG) use for sites that lack site-specific weigh-in-motion (WIM) data or have data of limited quality. This application can work with LTPP or user-provided WIM data summaries and produces axle load distribution input files for use with the National Cooperative Highway Research Program (NCHRP) 1-37A and AASHTOWare Pavement ME Design software products.
