USE OF ANTISTRIPPING ADDITIVES IN ASPHALTIC CONCRETE MIXTURES LABORATORY PHASE

This report reviews the current use of antistripping additives in asphaltic concrete mixtures and contains guidelines for incorporation of the additives into the paving mixtures in the field. A laboratory procedure is described in detail for predicting antistripping additive effectiveness for a specific asphalt-aggregate paving mixture. On the basis of this research and experience, it is recommended that the prediction procedure be used on a trial basis to estimate the effectiveness of various antistripping additives with different asphalt-aggregate mixtures.
