A recent state survey conducted by the American Association of State Highway and Transportation Officials (AASHTO) of all the products developed under the Strategic Highway Research Program (SHRP2) ranked a project conducted by the Texas A&M Transportation Institute’s (TTI) Flexible Pavements Program as its highest ranked for implementation. The project was led by Senior Research Engineer Tom Scullion and Associate Research Scientist Stephen Sebesta.
The project, sponsored and developed through SHRP2, involves two nondestructive techniques for detecting defect areas in new asphalt overlays during construction. Both technologies (infrared and radar) test essentially 100 percent of the pavement area, providing much more inspection coverage than existing quality control methods. Read More
