BTA混合料抗疲劳性能的试验研究

Experimental study on anti-fatigue performance of BTA mixture

在BTA混合料中分别掺量0.15%、0.3%、0.45%的木质素纤维,以提高混合料的抗疲劳性能。通过四点弯曲疲劳试验方法,分析了木质素纤维对BTA混合料疲劳性能的改善效果,提出以木质素纤维改善BTA混合料的疲劳方程并确定了木质素纤维的最佳用量。

To improve the anti-fatigue properties of the BTA mixture, it was added 0.15% ,0.3%,0.45% proportion of lignin fiber. The improvement effect of liguin fiber on the fatigue properties of BTA mixture was analyzed by four-point bending fatigue test. The fatigue equation of BTA mixture is proposed, and determined the optimal amount of liguin fiber.
