摘要: 沥青玛蹄脂碎石混合料(SMA)成功并且有效地应用于多国路面面层。针对纳黔高速公路,采用当地集料设计 SMA。通过两种粗集料(石灰岩、玄武岩)的不同配比作为分析对象,测试(马歇尔稳定度、动稳定度、低温弯曲试验、构 造深度、摩擦系数)得到沥青SMA体积参数和性能指标。分析得出的SMA是符合工程需要的优质面层材料,具有良 好的抗滑能力,低温抗裂性能和良好的耐久性。结果表明不同的集料配合比显著地改变了SMA混合料的性能。

关键词: SMA, 马歇尔稳定度, 抗滑值, 配合比, 构造深度

Abstract: Stone Matrix Asphalt ( SMA) is regularly and successfully used for surface courses in many countries. In this study SMA was designed using local aggregates for Na-Qian highway. Two coarse aggregates limestone and basalt were used in different blending ratio for comparative analysis in laboratory. Laboratory testing of the SMA surface mixtures was performed to determine volumetric and mixture specific characteristics. Testing included Marshall stability,dynamic stability,low temperature bending,texture depth,and friction coefficient. The results and analysis determined that SMA is a good surface meeting the project demands. It was concluded from this study that different aggregate blending can significantly alter the SMA mixture properties.

Key words: SMA, marshall stability, skid resistance, blending ratio, texture depth
