    [Industry news] Things you need to know about falling weight deflectometer

    The Falling Weight Deflectormeter (FWD) came into being in the early 1970s. It is a pulsed dynamic sinuometer. It simulates the instantaneous impact of automobile load on the road surface and obtains the instantaneous deformation of the road surface. Its measurement results are more accurate, and the information is large.

    [Industry news] The usage of falling weight deflectometer

    Different bending basin radii were used for different pavement structures. Subgrade or flexible base asphalt pavement, sensor distribution within 2.5m from the load center can be used. For high grade highway with semi-rigid base asphalt pavement, the radius of influence of bending and sinking should be 3 ~ 5m. The sensor shall be arranged within a range of 3 ~ 4m from the load center and automatically measured under computer control. All test data can be displayed on the screen or printed or stored in the computer. Load, sinkage (basin), temperature of road surface, mean value of sinkage, distance between measuring points, standard deviation, coefficient of variation and data representing sinkage value and evaluation result can be output.
