At Almondz we rely on the latest technology from around the world to build our Infrastructure projects. Falling Weight Deflectometer (FWD) is used around the world by Engineers to evaluate the physical properties of pavement in highways, local roads, airport, harbour areas and railway tracks. Falling Weight Deflectometer is a smart and fully automatic equipment built around intelligent microcontroller based system which, acquires and processed data at high speeds with high accuracy and reliability. FWD test for road is fully automated control system which is controlled by a processor to ensure consistent results. During testing, a FWD subjects the pavement surface to a load pulse which simulates the load produced by a rolling vehicle wheel. During the deflection test, the load pulse is produced by dropping a large weight onto a "buffer" which shapes the pulse, and then transmitted to the pavement through a circular load plate. Data are acquired from various sensors for use in post-test analysis of pavement properties.
