日本沥青胶结料弯曲试验的研究与应用

Study and Application of Bending Test of Asphalt Binder in Japan

胶结料弯曲试验是日本评价高性能改性沥青的重要试验,试验结果为弯曲工作量和弯曲刚度两个指标。我国规范尚未引进该试验。该文阐述了日本该试验的提出过程,以及对该胶结料试验指标与沥青混合料性能相关关系的研究;介绍了该试验的试验方法与误差控制;并提出了对该试验在我国推广可能的看法。

Asphalt binder bending test is an important test in Japan.Bending work load and bending stiffness can be got in conclusion.This test has not been introduced into China.In this paper,the study progress of this test and the relation between this test index and other asphalt mixture performance were studied.The method and error control of this test was described.The possibility of the introducing this test into China was proposed.
