摘　　要：沥青混合料组成设计的总目标是确定沥青混合料的最佳组成,而沥青用量对混合料的组成有非常重要的影响。在通过大马歇尔试验确定沥青稳定碎石基层混合料最佳沥青用量时,稳定度和流值可作为检测检验数据,密度、空隙率和饱和度等体积指标则是主要的设计依据。The general objective of asphalt mixture design is to determine the best asphalt mixture composition. The amount of asphalt mixture has very important influence on mixture composition. When the best asphalt content of the mixture used in asphalt stabilized macadam base is determined through new Marshall Experiment, stability value and flow value can be used as detection data, some volume index such as density, voidage and saturation are the main design basis.
