摘要
在探讨沥青混合料小梁弯曲试验的加载模式的基础上,分析双点加载模式的合理性,提出在试验条件允许的情况下,对沥青混合料弯曲试验可采取双点加载模式,以提高试验可靠度的建议。通过试验验证表明,双点加载试验变异性小、操作简单,可以推广应用。
On the basis of studies the loading model of beam bending test for bituminous mixture, this paper analyzes the rationality of two points loading model and suggests to adopt the latter in order to improve the test reliability. The author checks the reliability of different loading model by test, which manifests the two points loading has small variability and simple operation, it is suitable to apply in the test.
