  • Method and system for measuring deformation of a surface
    Patent number: 11338630
    Abstract: Deformation of a surface, such as a pavement surface is measured using a rolling weight or wheel carrying one or more accelerometers positioned to measure the deformation occurring at a point on or near the perimeter of the wheel. The weight is rolled over the surface to be measured. The signals developed by the one or more accelerometers during a stationary cycloidal period of the point on the perimeter of the wheel are analysed to provide a measure of surface deformation based on the one or more signals.
    Type: Grant
    Filed: December 2, 2016
    Date of Patent: May 24, 2022
    Assignee: PAVEMENT ANALYTICS LIMITED
    Inventor: Graham Alexander Salt
  • METHOD AND SYSTEM FOR MEASURING DEFORMATION OF A SURFACE
    Publication number: 20210080242
    Abstract: Deformation of a surface, such as a pavement surface is measured using a rolling weight or wheel carrying one or more gyroscopes positioned to measure the deformation occurring at a point on or near the perimeter of the wheel. The weight is rolled over the surface to be measured. The signals developed by the one or more gyroscopes during a stationary cycloidal period of the point on the perimeter of the wheel are analysed to provide a measure of surface deformation based on the one or more signals.
