| 摘 要： | 片麻岩在全国分布广泛，其储量仅次于石灰岩。文中对掺杂有片麻岩细集料的AC-13沥青混合料进行了空隙率、矿料间隙率、沥青饱和度，以及粗集料骨架间隙率的实验。结果表明，在相同配合比下，掺杂片麻岩细集料的沥青混合料体积指标与全部使用石灰岩的混合料存在差异，产生的原因是片麻岩细集料针片状颗粒的含量和强度不同。

| Abstract: | Gneiss is widely distributed throughout the country, its reserves is only next to limestone. In this paper some experiments about volume of air voids, voids in mineral aggregate, voids filled with asphalt and voids in the coarse aggregate of AC-13 asphalt mixture mixed with fine aggregate gneiss are performed. The results show that, under the same mix proportion, the volume index of asphalt mixture mixed with fine aggregate gneiss is different from that all use limestone, the reason is that the content and strength of needle flake particle is different. |
