开级配沥青磨耗层(OGFC)的研究

Study on the Design and Performance of the Open-graded Asphalt Friction Course

开级配沥青磨耗层是一种具有透水、防滑、降噪等功能的开级配混合料 ,但由于其空隙率较大 ,因此力学性能不足。针对路用开级配沥青磨耗层 (OGFC)混合料的组成成分及其特点 ,在其最佳沥青用量条件下研究了 OGFC沥青混合料的路用性能 ,并对聚合物纤维改性 OGFC混合料的路用性能进行了实验研究。结果表明 ,在 OGFC中加入纤维稳定剂可提高混合料的残留稳定度和抗车辙能力。

The components and characteristics of open-graded asphalt friction were studied. The pavement performances of anti-rutting and anti-sliding were introduced.The open-graded asphalt friction course containing polymer fiber was also studied. The result shows that the fiber additive can improve rutting and anti-water performance.
