Mastic and mortar are two bituminous composites which play a fundamental role in defining bituminous mixes’ properties. Therefore, the main purpose of this paper is to study the behaviour of these materials according to time and frequency with three different approaches: Experimental, analytical, and numerical. To characterise bitumen, mastic, and mortar, a Dynamic Oscillatory Test was carried out on bituminous composites using DSR. Numerically, mortar mechanical properties were assessed by applying a heterogeneous finite element (FE) modelling. Analytical methods such as Generalised self-consistent schemes (GSCS) and Shift-Homothety-Shift and time Shift (SHStS) have succeeded in predicting mastic and mortar properties. Numerical simulation presented a virtual DSR test able to examine stress and strain distribution in the digital model’s microstructure. Since studying the response of the internal structure to an applied stress or strain is complicated using other methods. Thus, aiming to optimise the material formula and improve its mechanical properties.

乳胶和砂浆是两种沥青复合材料，在定义沥青混合料的性能方面起着根本性的作用。因此，本文的主要目的是通过三种不同的方法，根据时间和频率来研究这些材料的行为：实验，分析和数值方法。为了表征沥青，乳香和砂浆，使用DSR对沥青复合材料进行了动态震荡试验。在数值上，通过应用非均质有限元（FE）模型来评估砂浆的力学性能。诸如广义自洽方案（GSCS）以及Shift-Homothety-Shift和Time Shift（SHStS）之类的分析方法已经成功地预测了胶泥和砂浆的性质。数值模拟提供了一种虚拟DSR测试，能够检查数字模型微结构中的应力和应变分布。由于使用其他方法研究内部结构对施加的应力或应变的响应非常复杂。因此，旨在优化材料配方并改善其机械性能。
