Developing a framework for diagnosis of shear distress in asphalt surfaces

Braking and turning by heavy vehicles can trigger shear-related distress in asphalt surfaces. The evolutionary increase in vehicle tyre pressure and wheel load will result in an increase in such surface failures in the future. Shear-related distress may result from delamination at the surface layer interface, or excessive shear creep within the asphalt surface layer itself. Both deformation and delamination distress appear visually identical at …
