【摘要】 从聚酯纤维和木质素纤维的微观特性出发,结合动态剪切流变试验,分析了纤维的自身特性对沥青胶浆高温性能的影响,并从界面化学和复合材料理论的角度对纤维的加强和改善作用机理进行了分析,结果表明,纤维的加入可以显著提高沥青胶浆的高温性能,且聚酯纤维作用效果更加明显。更多还原

【Abstract】 Through the micro-characteristics of the polyester fiber and methyl cellulose and the DSR results of fiber-asphalt glue, this paper analyzes the influence of fibers on the high-temperature performance of asphalt glue, and systemically investigates the fibers-enhanced mechanism with the theory of interface chemistry and compound-material. The results show that the fibers can prominently improve the high-temperature performance of asphalt glue, and the polyester fiber is more effective than methyl cellulose.更多还原
