Scope
This test method covers the determination of the pavement thickness by using magnetic pulse induction. This method is intended for use with plain jointed concrete pavements@ asphalt pavements@ base courses with cement binders and unbound aggregate layers. It is not applicable for continuously reinforced@ mesh reinforced@ or fiber reinforced pavement where the metal reinforcement would interfere with the magnetic field. The values stated in SI units are to be regarded as the standard. This standard does not purport to address all of the safety problems@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
