前言在修复日趋恶化的道路系统时,沥青路面再生是一项实用而经济的方案。除广泛应用热拌再生技术外,对沥青路面的冷拌再生正在进行评估。本项研究选择了径向回弹模量M_R试验来考察冷拌再生混合料的强度发展;并以维姆抗力R值、稳定度S值及粘结力C值来衡量混合料的性质。在现有乳化沥青混合料的技术的基础上,提出冷拌再生混合料的极限设计标准。
Introduction Asphalt pavement regeneration is a practical and economical solution to the deteriorating road system. In addition to the widespread use of hot mix regeneration technology, the assessment of cold mix regeneration of asphalt pavements is under way. In this study, the radial resilience modulus M_R test was chosen to investigate the strength development of the cold mix recycled mixes. The properties of the mixes were evaluated by the values of Vm resistance, stability S and cohesion C values. Based on the existing technology of emulsified asphalt mixture, the limit design standard of cold-mix recycled mixture is proposed.
