USE OF NONDESTRUCTIVE TESTING DEVICES IN THE EVALUATION OF AIRPORT PAVEMENTS

Data is analyzed as it applies to the use of nondestructive testing (NDT) to assist in conducting a destructive test program to evaluate the load carrying capacity of airport pavements. Different devices are available to perform these tests. The Benkelman beam, for example, senses the deflection of a pavement under actual loading configurations. Some electronic devices are also used to sense cracked pavements by wave velocity measurements. The procedures for the determination of the load bearing capacity of airport pavements using NDT techniques are considered to be less costly, present less interference to normal airport operations, and provide the evaluation engineer with more data on which to base his decision. Also, the dynamic stiffness modulus (DSM) values are useful for qualitative comparisons between one pavement area and another, and for locating areas which may show early distress. Appendices provide additional data, tables, charts and references.
