劈裂试验很早就被用于测定水泥混凝土材料的间接抗拉强度。从70年代起,美国的一些学者开始用来测定沥青混合料的劲度模量,1982年被收入ASTM标准。自那以后,劈裂试验用于沥青混合料的各种力学性能的研究而为世人所关注。本文试论将它用于蠕变及低频疲劳性能试验研究的结果。
Split tests have long been used to determine the indirect tensile strength of cementitious materials. Since the 1970s, some scholars in the United States began to measure the stiffness modulus of asphalt mixtures and were accepted into the ASTM standards in 1982. Since then, splitting tests have been of interest worldwide for the study of various mechanical properties of asphalt mixtures. This article discusses its use in creep and low frequency fatigue properties of experimental results.
