摘要
指出了轮辙试验动稳定度指标的不合理性 ,论述了指标数据离散性的原因。通过对轮辙试验较为系统详细的论述以及试验论证 ,提出用回归时间段内的动稳定度 DRS或永久变形 Rt来评价沥青混合料的高温稳定性更为合理。
The irrationality of indexes of rut tests is pointed out and the reason for notable detraction of rut test data systematically analysed in this paper.On the basis of rut tests of four kinds of gradation whose high temperature stability is judged before test, DRS(dynamic stability of regression) or R t (permanent deformation) are put forward,and that either of this two indexes to estimate high temperature stability of asphalt concrete is better is indicated. DRS or R tis obtained from regression for the data of rut tests.
