ABSTRACT
In this paper, the use of silane, an inorganic compound from semiconductor industry, is evaluated with the objective of improving the production and the performance of asphalt mixtures. Two types of asphalt mixtures commonly used in Germany, one for binder layer and one for wearing course, were prepared with and without silane. Mixing, compaction effort and volumetric properties were recorded, while low temperature tests were to determine the evolution the material thermal stress. The results suggest that, for comparable power demand, particles coating occurs 20% faster when silane is used. The compactability does not show any difference for both mixture types with and without silane. Similar bulk density was obtained for all asphalt mixtures. The low temperature behavior was not affected from silane addition, indicating that this additive can be potentially used for pavement applications.
