Falling Weight Deflectometer for Pavement Testing

Stanlay provides falling weight deflectometer (FWD) to evaluate the physical properties of pavement. FWD  is primarily used to estimate  pavement structural capacity for overlay design and  to determine if a pavement is being overloaded. The equipment is highly recommended for  highways, local roads, airport pavements .

The FWD is designed to impart a load pulse to the pavement surface which simulates the load produced by a rolling vehicle wheel. The load is produced by dropping a large weight, and transmitted to the pavement through  a circular load plate .

The PaveFWD / PaveHWD is necessary to evaluate and calculate surface conditions such as Bearing capacity, emoduli and expected service life of roads & highways i.e specifically bitumenous surface. The equipment is based on load cells and multiple geophones - is fast and requires 28 seconds to perform a test. The equipment is available in Trailer towed or Vehicle mounted versions and is available in 75kN to 250kN options.
