Abstract

In this study, bulk specific gravity measurements of coarse graded Hot Mix Asphalt were conducted using two methods, Parafilm(TM) and Corelok(TM). The measurements were compared for similarity and repeatability of results. The comparisons were made on two sets of specimens, unrutted and rutted specimens. The unrutted specimens were laboratory prepared beams and cores obtained from the field. The rutted specimens were laboratory prepared beams. Analysis of the data showed (1) based on regression analysis for both rutted and unrutted specimens there is a statistically significant difference between the measurements made by Parafilm(TM) and Corelok(TM) methods and (2) based on a one-way analysis of variance Corelok(TM) measurements are more repeatable for unrutted and rutted specimens than those made by Parafilm(TM). Additionally, for the rutted specimens, the bulk specific gravities measured by Parafilm(TM) were significantly lower than those measured by Corelok(TM). This is because the self-sealing parafilm bridges over large surface irregularities in contrast to the Corelok(TM), where the polymer Corelok(TM) bag follows the contours of the surface irregularities.
