Diagnostic technology "FWD"
It is possible to identify sections and layers that require repair! Evaluate the integrity of the pavement and the CBR of the subgrade without damaging the pavement.
"FWD" is a diagnostic technology that applies an impact load (standard 49 kN) to a paved surface and measures the deflection occurring in the surface using multiple displacement sensors at varying distances from the loading point. This allows for a non-destructive evaluation of the pavement structure from the obtained deflection curve. It enables the assessment of the pavement's integrity and the CBR of the subgrade without damaging the pavement. By performing inverse analysis of the deflection, it is possible to determine the remaining thickness of the pavement layers and their elastic coefficients. 【Features】 ■ Allows for the evaluation of the pavement's integrity and the CBR of the subgrade without damaging the pavement ■ By measuring at many points, it is possible to identify sections or layers that require repair ■ Can determine the remaining thickness and elastic coefficients of the pavement layers ■ Manufactured by Grontmij in the Netherlands, equipped with a loading plate, heavy weights, load measurement devices, and deflection measurement sensors in a one-box vehicle *For more details, please refer to the PDF materials or feel free to contact us.
