In this study, nanoindentation was conducted to extract the load-displacement behaviour and the nanomechanical properties of asphalt concrete across the mastic, matrix, and aggregate phases. Further, the performance of hydrated lime as an additive was assessed across the three phases. The hydrated lime containing samples have greater resistance to deformation in the mastic and matrix phases, in particular, the mastic. There is strong evidence suggesting that hydrated lime has the most potent effect on the mastic phase, with significant increase in hardness and stiffness.
在本研究中，进行了纳米压痕试验，以获取沥青混凝土在胶泥、基体和集料相中的载荷-位移行为及纳米力学性能。此外，还评估了熟石灰作为添加剂在这三个相中的性能。含熟石灰的样品在胶泥和基体相中，特别是在胶泥相中，具有更大的抗变形能力。有充分证据表明，熟石灰对胶泥相的影响最为显著，硬度和刚度显著增加。
