- 摘要:
- 将微藻油（MO）和苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）作为复合再生剂掺入老化沥青中，以制备MO/SBS复合再生沥青。对比了复合再生沥青的基本物理性能、高低温流变特性及疲劳特性，考察了MO与SBS的配比和用量对老化沥青再生效果的影响。结果表明，纯MO再生沥青的黏弹性变形能力可在一定程度上恢复至老化前水平，但仍有一定差距；MO/SBS复合再生则可在此基础上显著提升高温抗变形性能及弹性恢复性能，且其临界温度较老化前提高1.1~9.7 ℃，同时还降低了再生沥青对疲劳应变的敏感性以提高其抗疲劳性能。但MO/SBS复合再生沥青的低温蠕变变形能力相较于基质沥青有所降低。当MO和SBS的质量分数分别为8%和4%，复合再生沥青的高低温流变及疲劳特性较佳。
- Abstract:
- Microalgae oil (MO) and styrene-butadiene-styrene block copolymer (SBS) were used as composite regenerants to blend into aged asphalt to prepare MO/SBS composite regenerated asphalt. The basic physical properties, high and low temperature rheological characteristics and fatigue characteristics of composite recycled asphalt were compared. The effects of the ratio and amount of MO and SBS on the regeneration effect of aged asphalt were investigated. The results showed that the viscoelastic deformation ability of pure MO recycled asphalt could recover to a certain extent to the level before aging, but there was still a certain gap. On this basis, MO/SBS composite regeneration could significantly improve the high-temperature deformation resistance and elastic recovery performance, and its critical temperature was 1.1~9.7 ℃ higher than that before aging. At the same time, it also reduced the sensitivity of recycled asphalt to fatigue strain to improve fatigue resistance. However, the low-temperature creep deformation ability of MO/SBS composite recycled asphalt was lower than that of base asphalt. When the mass fraction of MO and SBS were 8% and 4%, the composite recycled asphalt had better rheological and fatigue characteristics at high and low temperature.
