Project Details

Project Description: 

Develop quality assurance/quality control (QA/QC) testing equipment and methodology and develop test procedure(s) for conducting noncontact strain measurement at the pavement surface and of asphalt mixtures (cores).

Goals 

The key project objective is to apply the sensitivity of laser shearography in measuring shear deformations to the development of new test methods for asphalt binders, asphalt mixes, and pavements.
