摘要

Five replicates of asphaltic concrete at five asphalt contents were produced and tested to compare maximum specific gravities determined by individual constituents, by solvent immersion, and by ASTM D-2041. The effects of variations in asphalt content on the maximum specific gravities obtained by the three methods were also considered. A statistically significant difference was found to exist between the solvent immersion and ASTM D-2041 methods at all five asphalt contents; whereas, no significant difference was found between the solvent immersion and individual constituents methods. There was a significant difference between the ASTM D-2041 method and individual constituents methods. This difference varies with asphalt content. Since the solvent immersion and ASTM D-2041 methods provide statistically different results, it is not appropriate to allow the use of both methods in the same specification unless separate acceptance limits are used. It is recommended that the solvent immersion method be eliminated from use since the ASTM D-2041 procedures are much more commonly used. To avoid the use of a correction factor to convert the ASTM D-2041 values to equivalent individual constituents values, as is currently done, it is recommended that the maximum specific gravity for job mix formula determination be established by the ASTM D-2041 method.
