【摘要】 通过大量 SHRP标准动态剪切试验 ,发现了不同温度下 G* / sinδ值变化规律 ,并建立了经验公式。由此可以根据沥青在某一适当温度时的 G* / sinδ值推算出其他温度的线性模型预测 G* / sinδ值。本文还建议了 2个参数 ,用以识别原样沥青和 SBS改性沥青更多还原

【Abstract】 In this paper, the simple relationship between G */sinδ and the different temperature is found by SHRP standard dynamic shear experiments of asphalts and modified asphalts, and empirical formula are proposed. By the proposed empirical formula the values of G */sinδ at other temperatures can be obtained if the value of G */sinδ at a given temperature is known. Two constants are suggested to identify asphalts and modified asphalts.更多还原
