| Abstract | The movement of superheavy loads (SHLs) has become more common over the years, since it is a vital necessity for many important industries, such as chemical, oil, electrical, and defense. SHL hauling units are much larger in size and weight compared to standard trucks. SHL vehicles' gross vehicle weights may be in excess of a few million pounds, so they often require specialized trailers and components with nonstandard spacing between tires and axles. Accommodating SHL movements requires the determination of whether the pavement is structurally adequate and involves the analysis of the likelihood of instantaneous or rapid load-induced shear failure. As part of this Federal Highway Administration project, Analysis Procedures for Evaluating Superheavy Load Movement on Flexible Pavements, an analysis package, Superheavy Load Vehicle Movement on Flexible Pavement (SuperPACK), was developed to evaluate specific cases of SHL-vehicle movements. This report describes the major components of SuperPACK: preanalysis modules (A modules), analysis modules (B modules), and an analysis engine (3D-Move ENHANCED). The A modules, which are required to proceed to the B modules, require information on vehicle axle configurations, material properties, subgrade shear strength parameters, and representative material properties for the analysis and reference vehicles. The B modules conduct bearing capacity, service limit, slope stability, buried utility, and cost allocation analyses. All the A and B modules require pavement responses, excepting the module on vehicle axle configurations. 3D-Move ENHANCED was developed to provide the modules with responses based upon the request. |
