使用三维浊度滴定法研究了新旧沥青粘合剂混合物的结构稳定性，其中三维是显示分散、极性和氢键成分的汉森溶解度参数的可视化。这项研究的目的是调查在沥青回收过程中新旧粘合剂混合的可能后果。然而，所用的滴定方法是新的，在开始评价新旧粘合剂混合物的结构稳定性之前，需要进行评估。结果表明，三维滴定给出了更详细的信息，结构稳定性，相比一维Heithaus滴定。还发现，用于自动检测降水的技术必须进一步发展。研究结果表明，只要新旧沥青混合料的结构稳定性良好，结构稳定性不是沥青再生的限制因素。
The structural stability of mixtures of old and new bituminous binders was studied using three-dimensional turbidimetric titration, where the three dimensions are a visualization of the Hansen solubility parameters showing dispersive, polar, and hydrogen-bonding components. The study was initiated to investigate the possible consequences of mixing old and new binders during asphalt recycling. However, the titration method used is new, and an assessment was needed before evaluation of the structural stability of mixtures of old and new binders could begin. The results showed that three-dimensional titration gives more-detailed information regarding structural stability, compared to one-dimensional Heithaus titration. It was also found that the technique used for automatic detection of precipitation must be further developed. The results regarding mixtures of old and new binders indicated that structural stability is not a limiting factor in asphalt recycling, provided that the old and new binders are compa...
