摘　　要：成型方式对设计的沥青混合料路用性能影响极大。现行SMA(沥青玛蹄脂碎石混合料)设计方法有很大的缺陷,为此提出新的SMA设计方法———GTM(旋转试验机)法。根据这种方法设计的SMA混合料密度高。室内试验及施工结果表明此种混合料有很好的高温、低温、抗水破坏及抗滑性能。文章最后介绍了SMA施工方法。Formation type is of great importance for road performance of designed asphalt mixture. However, there are serious defects existing in conventional SMA design method, and a new SMA design method-GTM has been proposed. SMA mixture made in this method has a high density. Laboratory tests and construction results show that the mixture is of good ability in aspects of heat && cold resistance, water resistance and clinging property. The SMA construction method is also introduced here.
