Research of AC - 20 asphalt mixture proportioning design on northern end of the capital airport F sliding

摘要

Because of the large load and large impact force of airport pavement under, it often appears the phenomenon of serious rut. In order to improve this kind of phenomenon, combined with the capital F slide northern area reconstruction project, we analyze the lower layer type of AC-20 modified asphalt mixture ratio design. We analysis from raw material selection, mixture gradation design and admixture added, and finally choose the excellent performance of asphalt mixture.
