Title:

Effect of Antistripping Additives on the Compaction of Bituminous Concrete
Authors:

VTRC No.: 82-R23
Abstract: The objective of this investigation was to determine the effect of antistripping additives on the compaction of bituminous concrete. To do this, the densities obtained on test sections with and without additive were compared. Comparisons of nuclear densities and the void contents of cores from the pavement revealed no significant differences. Also, there were no significant differences in the optimum numbers of roller passes required to attain maximum density on the sections with and without additive. The properties of the asphalt cement were probably not influenced enough by the additives to affect compaction. Based on the results of this investigation, the inability to achieve the desired density should not be attributed to the use of antistripping additives.
