A mineralogical approach of the interactions between bitumen, clay and water in hot mix asphalt (HMA)
Abstract
Clay fines are known to reduce the water resistance of bitumen-aggregates binding and cause stripping in Asphalt Concrete (AC) mixtures. To address this phenomenon, a better understanding of the mineralogical composition of aggregates is needed as well as an assessment of the bitumen-clay-water interactions. This paper contributes to reach this goal from a mineralogical perspective. The most common clays in natural aggregates, kaolinite, illite and montmorillonite, were used to prepare thin clay films and artificial clay-rich aggregates. The bitumen-clay interaction was studied using the sessile drop and the Oliensis spot tests on those thin clay films, whereas Duriez tests allowed measuring the stripping potential of AC mixtures containing the clay-rich aggregates. The results show that the water-bitumen-clay interaction and water resistance of the AC mixture are specific to the clay mineralogy. Furthermore, they show that the bitumenclay interaction may be captured upon determining the surface energy of bitumen, the chemical composition and pH value of the clay and the bitumen-clay compatibility. Hence, predicting the water resistance of clay rich AC mixtures from mineralogical properties of the bitumen-clay interaction seems feasible.
