Thermal imaging gives inspectors a faster, safer way to evaluate construction materials without causing damage. Learn how infrared cameras reveal temperature differences linked to delamination, voids, moisture, and paving issues, and how thermal imaging can support more efficient NDE and NDT inspections.

This guide covers the methods used to classify asphalt binders and how to perform these tests to ensure optimal pavement performance and longevity.
Continue Reading Performance-Graded Asphalt Binders: A Guide to Tests and Testing EquipmentMore than a century ago, Duff Abrams established a simple ratio to define the strength, quality, and workability of concrete mixtures. The water to cementitious material (w/cm) ratio is universally used in mixture design and batching, but accurate determinations for on-site acceptance of fresh concrete have remained elusive until now. The Phoenix method provides accurate and repeatable w/cm measurements in the lab or field in minutes.

Learn how to monitor and mitigate plastic shrinkage for optimum concrete results.
