Falling Weight Deflectometer




This device has several practical purposes in determining the properties of pavement. For one, Void s or empty spaces can be detected underneath the roadway. Joint testing determines how two abutting slabs of Concrete or Asphalt are fitting against one another. Other statical analyses determine the general strength of the structure, and can even predict what materials and in what combination were used to build the pavement if such information is unknown.
