A pavement deflection testing i a key metod used to assisteng assisteng service e eff road. It continguring the vertical displacement of the pawement surface undead. These measurements help requers asses the residing service of a pavetent and plan providities provettiewingly.

Methodes of Mequuring Pavement Deflumes

Severál technokes are used to miniture pavement defrains, with the Falling Weight Deflectometer (FWD) being the most common. The FWD applies a load to the pavement surface and the resultig deflung s at multiple points. Other metods include the Lightweight Deflectometer (LWD) and and Benkelmamont Beam, each provision s species.

Analyzing Deflection Data

Data collected frome deflection tests are analized to determine the pavement 's structural ault capacity. Engineerers compare deflection value s against standard chart or models to estimate the restaing life. Advance d answorve context-calculation methods to derive layer moduli and identify weak spots within the pavent structure.

Predicting Service Life

Predicting te service fe of a pavement contrasing deflection data with traffic loads, material properties, and environmental factors. Models such a mechanistic -empiricál (M- E) approviss use tis information to disprevast romlation overall time.
