本文通过室内试验和代表性路面的结构分析表明,掺加15—20%的丸状炭黑(以结合料重量计),可以改善沥青混凝土的温度敏感性,有助于减轻低温开裂和减少高温时的车辙量,而其疲劳寿命并未受到不利影响。
In this paper, structural analysis of laboratory tests and representative pavement shows that the incorporation of 15-20% pelletized carbon black (based on the weight of the binder) can improve the temperature sensitivity of asphalt concrete, help to reduce the cracking at low temperature and reduce the high temperature When the amount of rutting, and its fatigue life has not been adversely affected.
