Phạm vi áp dụng / Scope of standard

This method covers the in-place determination of the total density and relative compaction of HMA pavements by measuring changes in the electromagnetic field resulting from the compaction process.

The equipment referenced in this method is an electronic surface contact device that is relatively unaffected by the surface moisture and surface variances in temperatures typically encountered during HMA paving operations. If needed, it should include circuitry to measure/compensate for moisture and temperature variances during the material compaction process.

This procedure does not purport to address all of the safety concerns associated with its use. It is the responsibility of the user of this procedure to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
