The increasing scarcity of modified asphalt is affected by storage stability at the present , then the preparation of high strength bituminous mixture gradually become a trend which adopted by hard asphalt of low-grade . This paper determines appropriate mix through the laboratory tests for hard asphalt which was verified in the trial section proves that the desire for load performance in highway engineering can be satisfied with this asphalt type.
