摘要

冷回收材料(crbm)为路面提供了经济和环境优势，因为它们减少了能源和原材料的消耗。然而，机场路面的设计方法不包括关键的CRBM特性。本文采用经验-力学方法对机场路面设计进行了研究，以期为设计提供指导。本文的目的是获得在这种方法中使用所需的与材料特性相关的输入。为此，对含有再生沥青、粉煤灰、水泥和泡沫沥青作为稳定剂的CRBM进行了表征。方法包括应变控制模式下的间接拉伸刚度模量(ITSM)和间接拉伸疲劳试验(ITFT)。然后获得了使用CRBM进行路面设计分析所需的输入。结果表明，进一步研究CRBM疲劳对了解这些混合料在循环载荷下的行为具有重要意义。

Analysis of stiffness and fatigue resistance of cold recycled asphalt mixtures manufactured with foamed bitumen for their application to airfield pavement design

Cold recycled bound materials (CRBMs) provide an economic and environmental advantage for pavements since they decrease energy and raw material consumption. However, design methods for airfield pavements do not include key CRBM properties. In this paper an empirical-mechanistic method is used to study airfield pavement design with CRBM in order to develop design guidance. The aim of the paper is to obtain the inputs related to material properties needed for use in this method. For this purpose, CRBM containing reclaimed asphalt, with fly ash, cement and foamed bitumen as stabilising agents, was characterised. The methodology included indirect tensile stiffness modulus (ITSM) and indirect tensile fatigue tests (ITFT) in strain control mode. The inputs needed for a pavement design analysis with CRBM were then obtained. The results showed the importance of further study on CRBM fatigue to understand the behaviour of these mixes under cyclic loading.
