Investigation of nano ulexite mineral effects on mechanical behaviour of warm mix asphalt pavements

Tuba KÜTÜK, Resul Ekrem GÜNBEY

Abstract

The research presented in the paper shows that further investigations on additives used in the warm mix asphalt technology are needed. It was observed that the negative effect of adhesion loss in asphalt mixes produced by warm process can be reduced by adding ulexite mineral nano particles to a commercial additive. The Marshall stability, Indirect tensile strength modulus, and moisture susceptibility, were tested for this purpose. Based on the analysis of results, it can be seen that the WMA mixture production temperature can additionally be reduced, and that lower compaction energy is needed during placement of such mixtures, which results in energy savings.
