Abstract: In this paper the study of the mechanical properties and performance on the three SMA mixtures compared with that of one AC mixture is carried out. The results have shown that when most other conditions are of consistencg,the asphalt mixtures present the obviously different mechanical properties and performance if the gradation of aggregate mixture are changed.When the gradation of aggregate mixture is optimum,the mechanical properties and performance of asphalt mixtures will be enhanced greatly

Key words: the gradation of aggregate mixture, asphalt mixtures, the mechanical properties and performance, influence

摘要: 笔者对比研究了3种SMA混合料和一种AC混合料的力学性能和路用性能.结果表明,在其他条件相同的情 况下,集料混合料级配的不同,沥青混合料的力学性能和路用性能呈现出显著的差异.当集料混合料级配达到最佳 组成时,沥青混合料的各项力学性能和路用性能将显著提高.这不仅说明进行沥青混合料级配优化设计的重要性, 同时也说明了在沥青路面工程施工中严格控制沥青混合料级配的重要性
