The Effects of Variations in Specimen Height on the Marshall Properties of Asphaltic Concrete.

Abstract

A problem inherent in many standard test methods in materials engineering is the preparation of a representative or standard specimen. The Marshall Test, ASTM D 1559-76, 'Standard Test Method for Resistance to Plastic Flow of Bituminous Mixtures Using Marshall Apparatus,' is subject to variability introduced by nonstandard specimens. Standard sized specimens are compacted at specified temperatures using standard equipment and procedures. This study investigated the effects of variations in specimen size, specifically specimen height, on Marshall stability and flow. In order to determine the adequacy of accepted correction methods, the observed variability introduced by nonstandard specimen heights was compared to the accepted correction method. Recommendations concerning the correction of stability and flow values resulting from nonstandard specimens are presented. (Author)
