The influence of hydrated lime (HL) on linear viscoelastic (LVE) behavior of mastic is investigated. One bitumen and five mastics with different HL content are investigated. The same 35/50 penetration grade bitumen was tested and used for mastics preparation. The LVE properties were obtained by means of complex shear modulus tests using a dynamic shear rheometer (DSR) on a wide range of temperatures and frequencies.

The time–temperature superposition principle in the LVE domain was applicable. Experimental results were modeled using the 2S2P1D model previously developed at the University of Lyon/ENTPE. The reinforcement effect of HL on LVE behavior of mastics was observed and quantified. Results show that the volume of filler increase when limestone is replaced by HL at constant mass, may explain a large part of the observed stiffening effect.

研究了熟石灰（HL）对乳香树脂线性粘弹性（LVE）行为的影响。研究了一种沥青和五种不同HL含量的胶泥。测试了相同的35/50渗透级沥青，并用于制备胶泥。通过使用动态剪切流变仪（DSR）在较宽的温度和频率范围内进行复数剪切模量测试获得LVE特性。

LVE域中的时间-温度叠加原理是适用的。实验结果使用以前在里昂大学/ ENTPE开发的2S2P1D模型进行建模。观察并定量了HL对乳香LVE行为的增强作用。结果表明，当恒定质量的HL代替石灰石时，填料的体积会增加，这可以解释观察到的大部分硬化效果。
