Load Transfer Efficiency in Rigid Pavement (CE 441 – Design of Pavement)

This lecture provides a fundamental introduction to Load Transfer Efficiency (LTE) in rigid pavements as part of a pavement engineering course. Load Transfer Efficiency is used to evaluate how effectively wheel loads are transferred across joints in concrete pavements. The lecture explains the theoretical basis of LTE, the role of dowel bars, and how LTE is quantified using deflection measurements obtained from a Falling Weight Deflectometer (FWD). Key topics include: Thermal behavior of concrete pavements and jointed slab systems Structural role of dowel bars at pavement joints Deflection-based definition and equation for LTE FWD testing procedure for joint evaluation Interpretation of LTE for pavement performance Relationship between LTE and joint-related distresses such as faulting, pumping, and reflective cracking Intended audience: Senior undergraduate and graduate civil engineering students, pavement engineers, and transportation professionals.
