采用不同软化点的沥青,在不同温度下进行了沥青混合料的车辙试验,分析了不同沥青混合料的抗车辙能力随温度而变化的规律,首次提出了沥青混合料的“软化点”,即抗车辙临界温度的概念,并建立了该温度与沥青软化点的关系,为沥青混合料的选择及路用性能评价提供了一种新的途径。 Using different softening point bitumen, the rutting test of asphalt mixture was carried out at different temperatures. The law of rutting resistance of different asphalt mixtures with temperature was analyzed. The “softening point” of asphalt mixture was first proposed, that is, The concept of critical temperature of rutting is also established. The relationship between the temperature and softening point of asphalt is established, which provides a new way for the selection of asphalt mixture and the evaluation of road performance.
