Abstract

Hot asphalt mixtures are widely used as road pavement materials. But they require the optimun working temperature and consume the large quantities of energy. This paperpresents a method to reduse heating temperature of hot asphalt mixtures keeping the required conditions. This consists of produing micro-bubbles in binder using additives, and then improve the fluidity and compressibility. As the results, it is confirmed that the degree of compaction and mechanical properties of the asphalt mixtures of reduced heating are equal to generally used hot asphalt mixtures.
