摘要
现行《公路沥青路面施工技术规范》(JTJ0 32 - 94 )中沥青混凝土混合料组成设计中存在一些有争议的地方 ,本文在集料合成级配、沥青混凝土混合料理论最大密度计算方法、细集料的规格等方面提出了自己的看法与建议 ;并通过大量的试验找出了沥青混凝土混合料的空隙率与矿料级配的关系 ;
There are some disputed problems related to designing the proportioning of bituminous mixture in the ' Specifications for Construction Technologies of Highway Asphalt Pavement'. This paper puts forward some opinions and advices on aggregate synthetical grading, maximum theoretical density of bituminous mixture and fine aggregate's size of bituminous mixture, and gives the relationship between the aggregate synthetical grading and percentage of voids in bituminous mixture through a lot of experiments. It should be useful for designing the proportioning of bituminous mixture.
