文章结合具体高速公路工程,对沥青路面用聚酯纤维材料进行了研究,确定了具体工程应用纤维技术指标;对纤维沥青混合料配合比设计方法进行研究,提出了配合比设计控制要点;对设计沥青混合料分别进行了高温、低温及水稳定性性能试验研究,通过分析比较,我们认为在沥青混合料中添加纤维后可以有效改善沥青混合料性能,但是不同的纤维作用相差很大,实际工程中应通过严格的试验方法来确定实际路用聚酯纤维。
In this paper, the specific highway engineering, asphalt pavement with polyester fiber materials were studied to determine the specific engineering application of fiber technology indicators; fiber asphalt mixture mix design method research, put forward the mix design control points; design Asphalt mixture has been tested for high temperature, low temperature and water stability respectively. Through analysis and comparison, we believe that the addition of fiber in asphalt mixture can effectively improve the performance of asphalt mixture, but the effect of different fibers is quite different. Actual engineering In the strict test method to determine the actual use of polyester fiber.
