Currently, there is an overexploitation of natural resources worldwide due to the need to build various types of civil engineering infrastructure, such as buildings, bridges, housing and, in particular, roads. A large number of countries, including Mexico, additionally do not apply adequate treatment to the material resulting from the demolition of this type of work. Both situations generate significant environmental damage and contribute to the non-sustainability of the road construction sector. This research assesses the linear viscoelastic (LVE2) behavior of asphalt concrete specimens made with different combinations of mineral aggregate and construction and demolition waste (CDW). Complex dynamic modulus tests were performed in compression on cylindrical samples at different temperatures and frequency loading. The ANOVA analysis of test results indicate that the stiffness of the different asphalt concretes evaluated, represented by the complex dynamic modulus, tends to decrease with the temperature and increase with load frequency, which are typical of materials with viscous characteristics. The stiffness of the asphalt concrete evaluated does not show significant changes as the CDW aggregate content varies.

用建筑和拆迁废料（CDW）骨料生产的沥青混凝土的复数动态模量评估。

当前，由于需要建立各种类型的土木工程基础设施，例如建筑物，桥梁，房屋，特别是道路，因此对自然资源的过度开发。此外，包括墨西哥在内的许多国家还没有对拆除此类工作所产生的材料进行适当的处​​理。两种情况都会造成严重的环境破坏，并造成道路建设部门的非可持续性。这项研究评估了由矿物骨料与建筑和拆除废物（CDW）的不同组合制成的沥青混凝土标本的线性粘弹性（LVE2）性能。复杂的动态模量测试是在不同温度和频率负载下对圆柱形样品进行压缩试验。测试结果的ANOVA分析表明，以复数动态模量表示的所评估的不同沥青混凝土的刚度会随着温度的升高而降低，并随载荷频率的升高而升高，这是具有粘性特性的典型材料。随着CDW骨料含量的变化，所评估的沥青混凝土的刚度没有显示出明显的变化。
