Dutco Tennant LLC provides Falling Weight Deflectometer (FWD) to evaluate the physical properties of pavement. FWD is chiefly used to find out pavement’s structural capacity design and to decide if a pavement is overloaded. Apart from pavements, the equipment is suggested for highways, service roads, airport pavements, and others.
These lightweight Deflectometer equipment are important to evaluate and calculate surface conditions such as bearing capacity and predictable service life of roadways & highways, especially bituminous surface. The device is based on cells and many geophones – it is quick to function and requires a few seconds (around 28 seconds) to do a test. The equipment comes in Trailer towed or Car mounted versions and is available in multiple options.
Data collected from FWD can be used for determination of structural capacity of in-service pavements for analytical analysis of pavement performance, predicting layer moduli for pavement component layers, remaining life of pavements and in deciding strengthening and rehabilitation measures to be adopted for meeting the requirements. Analyses of data are being carried out using standard software as supplied by the manufacturer. Information such as load, layer types and thicknesses, range of moduli and Poisson’s ratio etc. for different layer materials would also be needed for FWD deflection data analysis. While carrying out analyses of data, it assumes material to be homogeneous, isotropic, linear elastic, weightless and semi-infinite.
Our Falling Weight Deflectometer (FWD) makes use of a dynamic weight that simulates the loading of a moving wheel. The pavement response is analyzed with pre-loaded software to find out the elastic moduli, stress, and strain of each layer. The equipment reports the weakest layer for failure, remaining life and find outs the optimum repairing alternatives. You can get the FWD as a trailer or a truck-mounted version satisfying all FWD standards worldwide.
