| 摘要: |
| 通过大量室内试验，以高温、疲劳和抗水损害性能作为主要检测项目，分别从3个方面评价环氧沥青混合料摊铺等待时间对其性能的影响，并通过灰关联分析法给出了环氧沥青混合料的最佳摊铺等待时间推荐值.结果表明：当摊铺等待时间小于30min时，环氧沥青混合料性能无变化；当灰关联综合性能下降至80%时，其摊铺等待时间最长，可达80min.这种方法可用于环氧沥青的研发和工程实践的评判. |

| Impact of Paving Waiting Time on Performance of Epoxy Asphalt Mixture |
|
|
| Abstract: |
| A large number of laboratory tests were carried out, which took high temperature, fatigue and moisture resistance as main test items. The research not only evaluated the impact of waiting time for paving on the performance of epoxy asphalt from three aspects, but also integrated these items and put forward suggestions on the value of waiting time for paving by the grey relationship analysis methods. The results indicate that if the waiting time for paving is less than 30 min, the performance of epoxy asphalt will remain unchanged; however, when the grey connection performance declines to 80%, it will take the longest waiting time for paving, which can be as long as 80 min. This method can be applied to the researches and developments of epoxy asphalt as well as the evaluation of engineering practice. |
