摘要
为了使室内加速养生更真实的模拟乳化沥青冷再生混合料施工现场实际的养生条件,采用宏观力学试验和工业CT的无损扫描试验研究了全封闭养生、开放养生、半封闭养生三种养生方式下乳化沥青冷再生混合料含水率、劈裂强度、抗压回弹模量的发展规律,并将其与路面芯样进行了对比,揭示了养生方式对乳化沥青冷再生混合料细微观空隙分布特征的影响机理,推荐采用半封闭40℃养生作为乳化沥青冷再生混合料的室内加速养生条件.
To ensure the indoor accelerated curing can better simulate actual curing conditions of emul‐sified asphalt cold recycled mixture ,non‐destructive industrial CT scanning tests and macroscopic me‐chanical test are used to study moisture content ,splitting strength ,and resilient Modulus transforma‐tion rule of emulsified asphalt cold recycled mixture under opened 、semi‐sealed、sealed three different curing methods ,revealed the influence mechanism of curing methods on fine micro voids distribution characteristics of cold recycled mixture .Finally ,40 ℃ semi‐sealed is recommended for the indoor ac‐celerated curing conditions of emulsified asphalt cold recycled mixture .
