蓄盐类SMA-13防凝冰沥青混合料高温性能试验研究

Study on High Temperature Performance of Salt Storage SMA-13 Anti-freezing Asphalt Mixture

采用正交试验的研究方法,对蓄盐类SMA-13汤青混合料的高温性能进行了试验研究,研究结果表明:影响蓄盐类沥青混合料高温性能的主要因素是集料级配及沥青用量,盐类抗凝冰剂对高温性能的影响较小,并通过试验确定了合理的盐类抗凝冰剂最佳用量。

Using Orthogonal experiment analysis method, the high temperature performance of salt storage SMA-13 asphalt mixture was studied. The research indicated that main factors which affected the perform- ance of SMA-13 asphalt mixture were aggregate graduation and asphalt content, the anti-freezing material had little effect, and the optimal dosage of anti-freezing material was chosen by experiment.
