| 摘 要： | 沥青混合料路面的压实度与空隙率是路面施工的重要质量检测指标,是沥青路面使用寿命最基本的保证.压实度与空隙率由于受原材料、混合料配合比设计、施工工艺和施工温度等因素的影响,会造成矿料骨架结构的变化,影响混合料的结构和强度;压实度与空隙率的变异性会影响到路面的强度、耐久性和防水性等,当路面发生脱粒、坑槽、渗水等病害时,追寻病害根源,分析压实度与空隙率的变异性是必要的.

| Abstract: | The detecting indexes for compactibility and porosity to asphalt mixture pavement construction are the most basic guarantee of service life of asphalt pavement.Due to effects of raw materials design of mixture proportioning,construction technology and temp etc,the compactibility and porosity will cause the change of skeleton structure of mineral aggregate and have impact on texture and strenght of mixture.The variabilities of compactibility and porosity also will affect the strength,durability and water-resistance of pavement.So it is requizite to find the root of disease and analyze the variabilities of compactibility and porosity as the pavement produces the spall,pot holes and seepage. |
