| 摘 要： | 通过对沥青混合料级配组成的分析和试件体积参数的分析,探讨以空隙率、理论最大密度和空隙率判别混合料级配离析的可能性,并提出判别沥青混合料级配离析程度的标准方法。试验和分析结果表明,沥青混合料级配离析程度可以用级配偏差值,沥青用量、空隙率和理论最大密度差值等指标进行评价和判别。

| Abstract: | The objective of this paper is to distinguish segregation of HMA(hot mix asphalt) on the basis of analysis of gradation and volumetric parameters of the test samples,and try to bring up a standard method of determining the segregation level.The results of tests and analysis show that the segregation level of HMA can be recognized and evaluated by grade-deviation,change of oil-content,voids in total mix and differences of theoretical maximum density. |
