沥青车辙因子在高温范围的经验回归关系

Empirical Regression Relation of Rut Factor in Range of High Temperature

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

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.
