| 摘 要： | 沥青稳定基层处在受压区，其永久变形主要是由于在荷载作用下，沥青混合料的压密以及局部颗粒的重新定向运动产生的。对于受压产生的永久变形，单轴压缩蠕变试验可以较好地模拟其实际的变形作用。通过试验证明，沥青稳定碎石基层混合料级配偏上限时，集料的间隙率呈减小趋势，抗永久变形能力提高。

| Abstract: | The asphalt - stabilized macadam base course is at the compressive zone, and its permanent deformation is mainly due to density of the mixture under the action of loads, and resulting from local particle re - orientation. The actual deformation may be simtdated by using the single - axial compaction creep test. The test has proven that the percentage of clearance in the mixture decreases when the gradation of asphalt - stabilized base course is at the upper limit and the ability to resist the permanent deformation is increased. |
