| 摘 要： | 通过室内试验和对比分析,研究乳化沥青的掺入对混合料干、温缩性能的影响。结果表明:乳化沥青的掺入使混合料的干缩应变、干缩失水率及干缩系数均有明显下降,温缩应变与温缩系数有些许下降;干燥养护下,乳化沥青水泥稳定碎石仍有良好的干缩性能。

| Abstract: | Laboratory experiments and comparative methods were used to study the dry shrinkage per formance, temperature shrinkage performance of the mixtures mixed with emulsified asphalt. The test results show that incorporation of emulsified asphalt mixture could make dry shrinkage, dehydration rate and dry shrinkage coefficient of mixtures decrease significantly. And the temperature shrinkage and the temperature shrinkage coefficient of mixtures decrease slightly. Under drying curing condi- tion, the emulsified asphalt cement-stabilized macadam still has good dry shrinkage performance. |
