TechBrief: Determination of Concrete Pavement Thickness Nondestructively Using the Magnetic Imaging Tomography Technique

General Interest: provides practical guidance to engineers responsible for the day-to-day design, construction, rehabilitation, maintenance, and management of pavements.

Primary Topic: Pavement Issues

Description: This technical summary discusses the application of a recently introduced technique, based on magnetic imaging tomography, to determine the thickness of freshly place concrete. This technique may be used for process testing and for acceptance testing during construction of new concrete pavements. The technique is applicable only to plain (nonreinforced) concrete pavements. The results of recent field trials using this technique are presented.
