Pavement Professor Breaks New Ground in Quality Control

摘要

For years, construction engineers have used ground-penetrating radar to locate unseen materials. But one scientist is trying to use the same technology to scan the molecular makeup of those materials. The new radar method has the attention of some pavement engineers who are on the hunt for more accurate, nondestructive test methods. The technique has the potential to save owners "a lot of money," according to Michael Lithman, vice president of Ellis & Associates Inc.
