摘要: 目的 针对高温地区重载重交通的二级公路,制备一种陶瓷-钢渣阻热耐磨型沥青混合料,对其路用性能进行研究。方法 将粒径4.75~9.5 mm的陶瓷和钢渣等体积代替同档位石灰岩集料的40%,陶瓷和钢渣的掺配比例分别设置为2:2、1:3和3:1。通过冻融劈裂试验、车辙试验评价该混合料的水稳定性和高温稳定性,通过室内光照辐射试验和加速磨耗试验验证混合料的阻热性能和耐磨性能。结果 结果表明:陶瓷和钢渣的加入会导致混合料的沥青用量增加,且陶瓷-钢渣沥青混合料水稳定性和抗车辙性能均有不同程度提高;陶瓷-钢渣沥青混合料降温效果比较显著,但长时间高温照射也会使上表面温度增加,且当二者掺量为2:2时在4 cm面层的最大温差为5.9 ℃,阻热效果最好;钢渣强度高,表面粗糙度多孔,与沥青结合牢固,其掺量对耐磨性能的影响较大,且随着钢渣掺量增加,耐磨性能提高得越显著,当钢渣掺量为30% 时,试件在加速磨耗试验中的质量损失最低,为227.1 g,耐磨性能相比于常规纯石灰岩沥青混合料提高了25.10%。结论 根据掺配比例不同导致沥青混合料性能变化规律不同,建议陶瓷-钢渣掺量比例控制在2:2左右,沥青混合料综合性能最优,且便于施工配料。

Abstract: Objectives For secondary highways with heavy traffic in high-temperature areas, a ceramic-steel slag heat-resistant and wear-resistant asphalt mixture was prepared, and its pavement performance was studied. Methods Ceramic and steel slag with particle sizes ranging from 4.75mm to 9.5mm were used to replace 40% of the equivalent-grade limestone aggregate by volume, with ceramic and steel slag mixing ratios set at 2:2, 1:3, and 3:1, respectively. The water stability and high-temperature stability of the mixture were evaluated through freeze-thaw splitting tests and rutting tests, while its heat resistance and wear resistance were verified through indoor light radiation tests and accelerated wear tests. Results The results show that the addition of ceramic and steel slag increases the asphalt content of the mixture, and the ceramic-steel slag asphalt mixture exhibits varying degrees of improvement in water stability and rutting resistance. The cooling effect of the ceramic-steel slag asphalt mixture is relatively significant, but prolonged high-temperature exposure also increases the surface temperature. When the mixing ratio of ceramic and steel slag is 2:2, the maximum temperature difference at the 4cm surface layer is 5.9°C, indicating the best heat resistance effect. The cooling effect of the ceramic-steel slag asphalt mixture is relatively significant, but prolonged high-temperature exposure also increases the surface temperature. When the mixing ratio of ceramic and steel slag is 2:2, the maximum temperature difference at the 4cm surface layer is 5.9°C, indicating the best heat resistance effect. Steel slag has high strength, a rough and porous surface, and forms a strong bond with asphalt. Its content significantly affects wear resistance, with the wear resistance improving more significantly as the steel slag content increases. When the steel slag content is 30%, the test specimen has the lowest mass loss in the accelerated wear test, at 227.1g, which is a 25.10% improvement over conventional pure limestone asphalt mixtures. Conclusions Based on the different performance changes resulting from varying mixing ratios, it is recommended that the ceramic-steel slag mixing ratio be controlled at approximately 2:2, which optimizes the overall performance of the asphalt mixture and facilitates construction and material preparation.
