基于沥青胶浆动态力学性能的纤维复配研究

摘要

The paper adopts the orthogonal experimental design method,regards the rutting factor,fatigue factor,and stiffness modulus as the e-valuation coefficients for the modified asphalt mastic dynamic mechanic performance by DSR and BBR tests,and researches the mixing propor-tions for the lignin fiber,polyester fiber and basalt fiber by combining with the grey relational analysis and comprehensive evaluation methods,so as to select the optimal compounding proportion.%采用正交试验设计法，通过DSR与BBR试验，以车辙因子、疲劳因子和劲度模量作为改性沥青胶浆动态力学性能评价指标，并结合灰关联分析和综合评价方法，研究了木质素纤维、聚酯纤维和玄武岩纤维之间的掺配比例，以选择出最佳的复配比例。
