Transcript of Use of 3D Imaging to Improve Asphalt Pavements

Typical Asphalt Road Structure
Are Michigan roads too rough?
What is MSU doing to make them look like this?
Using 3D vision / image analysis methods...
Get an asphalt sample from the field
METHODOLOGY
Take the sample to laboratory
Capture images using stereo cameras during testing
Compute strains (normalized deformation) using image analysis
Use of 'Stereo' imaging to obtain 3D strain distribution
Next step...
Modeling helps in ...
RAVELING
FATIGUE CRACKING
LOW TEMPERATURE CRACKING
POT HOLES
LONGITUDINAL CRACKING
BLOCK CRACKING
PLASTIC DEFORMATION/SHEARING
3D IMAGING FOR BETTER ROADS
Finding the appropriate materials and construction methods to prevent 'distresses' such as ....
