Precision of Marshall stability and flow test using 6-in. (152.4-mm) diameter specimens
Earlier studies have shown that the repeatability of Marshall stability, flow, and air voids content measurements on 6-inch (152.4 mm) diameter specimens of large stone mixes is better than the repeatability on 4-inch (101.6 mm) diameter specimens. A round robin study involving twelve participating laboratories was conducted to provide information for developing a precision statement for the ASTM Test Method for Resistance to Plastic Flow of Bituminous Mixtures Using Marshall Apparatus (6 inch-Diameter Specimen) (D 5581). Difference two-sigma (d2s) limits were developed to determine acceptable single and multilaboratory differences for bulk specific gravity, percent voids, Marshall stability, and Marshall flow measurements. Analysis of other data collected during the study indicated that stability and flow measurements are not sensitive to minor differences in various 6-inch (152.4 mm) diameter breaking heads currently in use.
