介绍了按主骨料空隙填充 (CAVF)法设计富沥青混合料的步骤 ,着重讨论了最佳沥青用量的确定。实验研究与工程实践均表明 ,根据这种方法设计的富沥青混合料在保证其他路用性能的同时 ,抵抗反射裂缝的能力明显高于其它混合料 ,适宜作旧混凝土路面上的加铺层材料。
The procedure of designing asphalt mixture by CAVF is introduced, and the determination of the optimal asphalt dosage is mainly discussed. Experimental studies and engineering practice have shown that the asphalt mixture designed according to this method can significantly improve the resistance of reflective cracks to other road mixes while ensuring other road performance and is suitable for the overlay material on the old concrete pavement .
