The impacts of superheavy load (SHL) movement on flexible pavements – and processes for best handling that – will be the subject of a free upcoming Transportation Research Board webinar.
It’s part of a U.S. Federal Highway Administration-sponsored research project.
SHL hauling units are much larger and heavier than standard trucks and may involve gross vehicle weights in excess of a few million pounds, which at times requires specialized trailers and components with nonstandard spacing between the tires and axles, according to TRB.
The presenters will discuss analysis methods to determine whether a pavement is structurally adequate to sustain SHL movement.
These will include subgrade bearing failure analysis, sloped pavement shoulder failure analysis, buried utility risk analysis, localized shear failure analysis, deflection-based service limit analysis, and cost allocation analysis.
