ANTISTRIPPING ADDITIVES IN LIEU OF MINERAL FILLERS IN ASPHALTIC CONCRETE MIXTURES

This report is concerned with the comparative evaluation of sand-gravel-asphalt mixtures with and without mineral fillers and with antistripping additives in place of mineral fillers. This comparative evaluation was based on Marshall Test criteria and visual observation of stripping of asphalt from aggregate surfaces under the action of water at elevated temperatures for a specified time. The evaluation of various mixes indicated: (1) a loss of stability and density of mixtures containing additive and no mineral filler; (2) that, in general, mixes made with North Louisiana aggregate are more prone to stripping conditions than those made with South Louisiana aggregate; and (3) that certain asphalts tend to contribute to the stripping phenomenon regardless of aggregate source. /FHWA/
