Pavement deflection testing is a standardized test method performed to non-destructively and quickly measure the strength and structural capacity of an in-place pavement structure. The test involves applying a load on the pavement surface, simulating a passing vehicle, and then measuring the resulting deflection or deformation of the pavement under that load.
This data is essential for identifying the structural condition of the in-place pavement, predicting its remaining service life, and determining the needed structural improvements to support future traffic. Deflection testing provides insightful information that allows cost-effective pavement rehabilitation strategies to be developed.
