摘要:
为验证铁尾矿对热拌沥青混合料微波加热愈合的提升效果,将铁尾矿料与天然碎石按不同比例混合制备铁尾矿热拌沥青混合料(IT-HMA),并测试IT-HMA的路用性能; 基于微波加热升温试验和微波加热愈合试验,研究铁尾矿掺量、钢纤维掺量、愈合环境和微波加热参数对IT-HMA升温特性与愈合性能的影响规律。研究结果表明,当铁尾矿掺量超过60%后,IT-HMA的路用性能已不满足规范要求,铁尾矿掺量为60%和80%的IT-HMA分别掺入1%和2%钢纤维后,其路用性能大幅提升且能满足规范要求; 随着铁尾矿与钢纤维掺量的增加,IT-HMA的微波加热升温速度更快,幅度更大,愈合效果随之大幅提升,主要原因是铁尾矿和钢纤维提升了沥青混合料的微波吸收能力,增强了断裂处沥青的流动性; 当铁尾矿掺量为80%、钢纤维掺量为2%时,愈合性能可达到对照组的1.91倍; 与常温干燥路面服役条件相比,浸水和冻融条件下IT-HMA的微波加热愈合性能至少分别降低13%和43%,且损伤程度越大愈合效果越差,因此应在雨季和冬季前及时实施微波加热修复; IT-HMA的微波加热愈合性能随单次微波加热时间的延长先增加后降低,随微波加热次数的增加逐渐降低,过长的微波加热时间和频繁的微波加热都会损害愈合性能。研究成果在揭示IT-HMA微波加热愈合性能变化规律的同时,也为铁尾矿在沥青路面中的高值化利用提供了理论基础。
Abstract:
To verify the enhancement effect of iron tailings on the microwave heating healing of hot mix asphalt, the iron tailings were mixed with natural crushed stones in different proportions to prepare iron tailings hot mix asphalt(IT-HMA), and the road performance was evaluated. Through microwave heating temperature rise tests and healing tests, the effects of iron tailing content, steel fiber content, healing environment, and microwave heating parameters on the temperature rise characteristics and healing performance of IT-HMA were investigated. The research results indicate that when the iron tailing content exceeds 60%, the road performance of IT-HMA no longer meets the specification requirements. After adding 1% and 2% steel fibers to IT-HMA with iron tailing contents of 60% and 80%, respectively, the road performance significantly improves and meets the specification requirements. As the iron tailing and steel fiber contents increase, the microwave heating temperature rise rate of IT-HMA becomes faster with a greater temperature rise, resulting in a substantial enhancement in the healing effect. The primary reason for this improvement is that iron tailings and steel fibers increase the microwave absorption capacity of the asphalt mixture, thereby enhancing the flowability of the asphalt at the fracture interface. With 80% iron tailings and 2% steel fibers, the healing performance reaches 1.91 times that of the control group. Compared to the service condition of dry pavement at room temperature, the healing performance of IT-HMA after water immersion and freeze-thaw conditioning decreases by at least 13% and 43%, respectively, with more severe damage resulting in poorer healing effect. Therefore, the microwave heating repair should be performed promptly before rainy or winter seasons. The healing performance of IT-HMA initially increases but then decreases with the extension of single microwave heating duration and gradually declines with the increase in the microwave heating frequency. Both the excessive microwave heating duration and frequent microwave heatingimpair the healing performance. The research results reveal the changing patterns of healing performance of IT-HMA under the microwave heating, at the same time, they provide a theoretical foundation for the high-value utilization of iron tailings in asphalt pavement.11 tabs, 12 figs, 38 refs.
