摘要:
为缓解城市热岛效应并解决彩色沥青路面高温稳定性差的问题,采用有机硅-聚丙酸酯(SMP)对明色沥青(CA)进行改性,得到有机硅-聚丙酸酯改性明色沥青(SMPA)。制备不同SMP掺量(质量分数分别为1%、2%、3%、4%、5%)的SMPA,并以基质沥青(BA)和SBS改性沥青(SBSA)作为对照,通过频率扫描、温度扫描和多重应力蠕变恢复试验评价SMPA的高温流变性能。同时,利用弯曲梁流变仪测试SMPA的蠕变劲度和蠕变速率,结合Burgers模型解析其低温黏弹参数。研究结果表明:SMP掺入可显著提升CA的复数模量,使其在高温低频条件下表现出优异的抗变形与抗车辙能力,且随掺量增加高温性能增强效果更为明显; 车辙因子与疲劳因子表明SMPA兼具良好的高温稳定性与较好的抗疲劳性能,且其感温性能改善作用存在饱和趋势; SMP掺量的提升能够显著改善CA的蠕变恢复特性,并使其不可恢复蠕变柔量持续降低,掺量为3%的SMPA相较CA蠕变恢复率提高4.8%,不可恢复蠕变柔量逐渐降低22.1%,提高了CA的高温抗变形能力与恢复变形能力; SMP的掺入对CA的蠕变劲度与蠕变速率影响幅度不大,掺量为3%的SMPA相较CA蠕变劲度提高3.1%,蠕变速率降低1.3%,对CA的低温抗裂性能影响可控; 综合高低温性能评价,SMPA具有优异的高温性能,但其低温性能略有下降; 通过平衡抗车辙性与抗裂性,确定SMP最佳掺量为3%,研究结果为明色沥青的性能优化与工程应用提供了理论依据。
Abstract:
To mitigate the urban heat island effect and address the issue of inadequate high temperature stability in clear asphalt pavement, silane-modified polyacrylate(SMP)was used to modify clear asphalt(CA), and its rheological properties were investigated. SMP modified clear asphalt(SMPA)with different SMP mass fractions(1%, 2%, 3%, 4%, and 5%)was prepared, and base asphalt(BA)and SBS-modified asphalt(SBSA)were used as controls, and the high temperature rheological properties of SMPA were evaluated by frequency sweep tests, temperature sweep tests and multiple stress creep recovery tests. At the same time, the bending beam rheometer was used to characterize the creep stiffness and creep rate of SMPA, and its low temperature viscoelastic parameters were analyzed by Burgers model. The results indicate that the addition of SMP significantly improves the complex modulus of CA, so that it exhibits excellent anti-deformation and anti-rutting ability under high temperature and low frequency conditions, and the high temperature performance enhancement effect is more obvious with the increase of SMP content. Rutting factor and fatigue factor show that SMPA has good high temperature stability and good fatigue resistance, and its temperature sensitivity improvement has a saturation trend. The increase in SMP content significantly improves the creep recovery properties of CA and continuously reduces its non-recoverable creep compliance. Compared with CA, the creep recovery rate of SMPA with 3% content increases by4.8%, and the unrecoverable creep compliance gradually decreases by 22.1%, which improves the high temperature deformation resistance and recovery deformation ability of CA. The incorporation of SMP has little effect on the creep stiffness and creep rate of CA. Compared with CA, the creep stiffness of SMPA with 3% content increases by 3.1%, and the creep rate reduces by 1.3%, which has a controllable effect on the low temperature crack resistance of CA. According to the evaluation of high and low temperature performances, SMPA has excellent high temperature performance, but its low temperature performance decreases slightly. By balancing the rutting resistance and crack resistance, the optimum SMP dosage is determined to be 3%. The research results provide a theoretical basis for the performance optimization and engineering application of clear asphalt. 6 tabs, 12 figs, 38 refs.
