What is it about?
This review article examines how engineers measure load transfer (LT) capacity in Portland Cement Concrete Pavements (PCCPs) – a key factor in pavement durability and performance. Load transfer refers to how a concrete slab shares weight with adjacent slabs at joints and cracks. The paper critically evaluates existing field-testing methods (e.g., Falling Weight Deflectometer) and identifies gaps in current practices. It then proposes a framework for more accurate, practical, and advanced field-evaluation techniques to assess LT capacity under real-world conditions.

Why is it important?
Poor load transfer accelerates pavement deterioration, leading to costly repairs, traffic disruptions, and shorter road lifespan. Traditional evaluation methods often miss critical variables like environmental effects, joint deterioration, or dynamic traffic loads. By advancing how LT capacity is measured in the field, this work helps engineers design longer-lasting pavements, optimize maintenance budgets, and improve road safety. For policymakers and funders, better evaluation means more resilient infrastructure and lower long-term costs.
Perspectives
Academic perspective: Provides a systematic gap analysis of current LT evaluation models and calls for hybrid experimental-numerical approaches. Engineering practice perspective: Emphasizes practical, non-destructive, and repeatable field methods suitable for routine pavement assessment. Policy & infrastructure management perspective: Supports data-driven decision-making for pavement preservation and rehabilitation funding. Industry/innovation perspective: Highlights opportunities for new sensor technologies, automated data interpretation, and integration with pavement management systems.
