| 摘 要： | 粗骨料多用于形成骨架空隙结构,依靠粗集料相互嵌挤及其间的内摩阻力形成强度,进而使得结构坚实,促进排水。为了研究乳化沥青冷再生混合料中粗集料是否形成骨架结构,是否有助于提高乳化沥青冷再生沥青混合料的稳定性和耐久性,选取4种级配的混合料,通过马歇尔试验、车辙试验、冻融劈裂试验等,分析了4种不同含量粗集料对沥青混合料空隙率、高温稳定性、水稳定性能的影响。

| Abstract: | Coarse aggregate is used to form the skeleton gap structure,relying on its embedded pressure and friction to form the strength,then make a solid structure and promote drainage.In order to study whether the skeleton structure of the coarse aggregate in emulsified asphalt cold mixtures is formed,and it will help to improve the stability and durability of emulsified asphalt cold mixtures or not.Selecting 4 kinds gradation of mixtures,through the Marshall test,track test,freeze - thaw splitting test,such as,ana... |
