This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, presents evaluations of the capability of portable spectroscopy devices to “fingerprint” typical construction materials. The spectroscopy devices are evaluated in laboratory conditions as well as in the field to verify material-testing method combinations found successful. The report also documents simple, easy-to-use nondestructive testing procedures for use in the field to ensure quality construction.
