The method entails utilizing information obtained from Falling Weight Deflectometer (FWD) testing to estimate a numerical index representing the general load-carrying capability of a pavement construction. The FWD applies a managed impulse load to the pavement floor, and sensors measure the ensuing deflections at numerous distances from the load. These deflection measurements are then utilized in backcalculation procedures to estimate the elastic moduli of the pavement layers. The structural quantity is in the end derived from these moduli and layer thicknesses.
This analysis methodology is crucial for pavement administration and rehabilitation planning. Correct evaluation of structural capability permits engineers to establish pavement sections which can be structurally poor and prioritize upkeep or rehabilitation efforts. This method gives a non-destructive different to harmful testing strategies, lowering disruption to site visitors circulate. Traditionally, this analysis course of has enabled knowledgeable selections relating to useful resource allocation, extending pavement service life, and optimizing funding in infrastructure.
