Effect of Fine Aggregate on Properties of Asphalt Mixture

Abstract:

The fine aggregate plays a vital role in the performances of asphalt mixture. In this paper, four kinds of fine aggregates with different lithology, apparent density and water absorption rate were discussed. Asphalt mixture according to AC-13 is prepared by these four kinds of fine aggregates and the volumetric properties, water stability performance and high temperature performance of asphalt mixture were tested. Research shows that: the aggregate performance and the performance of mixture have obvious corresponding relation, which provides the theoretical basis for the engineering application of composite aggregates.
