Abstract:

A method for correcting roughness of pavement wherein the steps include measuring an elevation profile of the pavement, converting the elevation profile to a roughness profile, and identifying defective segments of the roughness profile as those areas of the profile exceeding a predetermined value. A grinder is simulated over the defective segments to provide a modified elevation profile. The modified elevation profile is converted to a modified roughness profile wherein corrected defective segments are identified as defective segments in the roughness profile that exceed the predetermined value in the modified roughness profile. A grinding operation is then applied to those areas of the pavement corresponding to the defective segments.
