摘要
采用 Superpave 剪切试验机,在保持沥青混合料试件高度不变的条件下,以控制应变方式对试件施加正弦波形剪切荷载,进行重复加载试验,试验在不同频率下进行,试验结果可用于评价沥青混合料的高温性能。
A repeated sinusoidal shearing load is applied to the asphalt mixture specimen at constant height to achieve a controlled shearing strain using SUPERPAVE Shear Tester.This test is performed at different frequency.The testing result could be used evaluating the high tem- perature performance of asphalt mixture.
