Abstract
The invention relates to mix composition determination method of coarse graded high modulus asphalt concrete with skeleton embedded structure, which belongs to the road engineering design field. The invention use low labeled hard asphalt AH-30# with penetration degree no greater than 30 (0.1 mm); the nominal maximum aggregate size no smaller than 26.5 mm; building mineral aggregate gradation of the mix using course aggregate gap gradation; using gradation design method of asphalt mixture based on closest compact condition to select the optimal oil-stone ratio.
