| 摘 要： | 无需通过马歇尔试验，而依据对SMA空隙率、矿料间隙率及沥青饱和度等体积特性的标准要求，反算出马歇尔试件毛体积相对密度应有的取值，在此基础上提出了一种判断sMA粗集料嵌挤状态的简便方法。即，只要反算的毛体积相对密度大于粗集料松装相对密度与粗集料用量的比值，粗集料就能形成嵌挤状态。

| Abstract: | Without Marshall test,the bulk volume relative density of Marshall specimen can be calculated according to some volume character requirements,such as VV,VMA and VFM.So a short-cut method for judging interlocking conditions of SMA coarse aggregates is suggested: if the calculation value of the bulk volume relative density is greater the ratio of coarse aggregate relative density to coarse aggregates dosage,coarse aggregates can come into interlocking conditions. |
