DEGREE OF COMPACTION OR VOIDS CONTENT AS AN ACCEPTANCE CRITERION?

VERDICHTUNGSGRAD ODER HOHLRAUMGEHALT ALS ABNAHMEKRITERIUM?

THE AUTHOR DISCUSSES THE CONCEPTS OF NET DENSITY, GROSS DENSITY, BULK DENSITY AND VIBRATED DENSITY, AND FOLLOWS THIS WITH DETAILS OF THE DEFINITIONS AND TECHNICAL SIGNIFICANCE OF DEGREE OF COMPACTION AND VOIDS CONTENT. MATHEMATICAL PROOF IS GIVEN OF THE FACT THAT THE DEGREE OF COMPACTION AND VOIDS CONTENT INTHE SURFACING ARE FUNCTIONALLY LINKED WITH THE VOIDS CONTENT IN THE MARSHALL SAMPLE. THE ORDER OF MAGNITUDE OF POSSIBLE ERRORS ESTABLISHED (WITH BOTH DENSITY CRITERIA) IS ROUGHLY EQUIVALENT; THIS OPENS UP THE POSSIBILITY OF ELIMINATING ONE OF THE TWO FEATURES. AS THE SPECIALIST CAN USE VOIDS CONTENT TO PREDICT PROBABLE PROPERTIES OF THE ASPHALT WHEN IT IS IN USE - RESISTANCE TO DEFORMATION. SUBSEQUENT COMPACTION, RESISTANCE TO WINTER STRESSES, POSSIBLE HARDENING OF THE BINDER ETC. - PREFERENCE SHOULD BE GIVEN TO THIS PROPERTY AS AN ACCEPTANCE CRITERION.
