摘要:
为确定胶粉级配对橡胶沥青性能的影响,选取8种胶粉级配,基于不同胶粉级配进行定量评价,分别采用常规性能、流变性能和弯曲蠕变劲度试验评价了胶粉级配对橡胶沥青常规性能和高低温性能的影响,通过热重、荧光显微镜和溶解度测试分析了不同胶粉级配橡胶沥青的微观性能。结果表明,随着胶粉级配变细,橡胶沥青的针入度上升,软化点和黏度下降,延度和储存稳定性得到提高。级配越粗对橡胶沥青高温性能的提升效果越好,而级配越细对低温性能提升效果越好。胶粉级配参数与橡胶沥青性能有良好的相关性。粗级配胶粉沥青的高温稳定性更好;细级配胶粉在沥青中有更好的相容性和更大的降解程度,从而提升了橡胶沥青的储存稳定性。
Abstract:
To determine the influence of rubber powder grade on performance of rubber asphalt, 8 rubber powder grade were selected for quantitative evaluation. Conventional performance, rheological performance, and bending creep stiffness tests were conducted based on different rubber powder grade to evaluate their effects on the conventional performance and high- and low-temperature performance of rubber asphalt. The microscopic properties of rubber asphalt with different rubber powder grade were analyzed through thermogravimetric analysis, fluorescence microscopy and solubility test. The results indicated that as the rubber powder grade became fi-ner, the penetration of the rubber asphalt increased, while the softening point and the viscosity decreased, and the ductility and storage stability improved. Coarser grade had a better effect on improving the high-temperature performance of the rubber asphalt, while finer grade had a better effect on improving low-temperature performance. There was a good correlation between the rubber powder grade parameters and the performance of rubber asphalt. The rubber asphalt with coarser grade exhibited better high-temperature stability, while the rubber asphalt with finer grade showed better compatibility and greater degradation in asphalt, thereby improving the storage stability of the rubber asphalt.
