Abstract

Abstract

In order to compare the different degrees of the aggregate segregations for asphalt mixtures with different gradation types during construction, seven kinds of asphalt mixtures with typical gradation types were produced by adjusting the scale of hot bunker at mixer plant, and the granulometric composition conditions at different positions on cross section after spreading were analyzed.After the mixtures were rolled and molded, their construct depthes were measured at different positions on cross section, and their numerical characteristics were evaluated.Analysis result shows that, on the same condition, the gradations that influence the degrees of the aggregate segregations from large to small were in the following order: counter S type, discontinuous type, the micro bow type that is over the ultimate density curve, S type, 0.45 capital ultimate density curve, the gradation with superior middle particle size, the micro bow type that is below the ultimate density curve.
