结合两条典型重载交通山区高速公路车辙病害形成特点,分析交通量及交通组成、交通荷载、长大纵坡及持续高温最不利组合的外部因素和沥青混合料高温稳定性能不足的内部因素,对重载交通下山区高速公路车辙病害的影响,提出相应的车辙预防措施与对策。 Combining with the formation of rut disease of two typical heavy traffic mountain expressways, the internal factors such as external factors of traffic volume and traffic composition, traffic load, long and long-term vertical gradient and the most unfavorable combination of sustained high temperature and insufficient high temperature stability of asphalt mixture are analyzed. The impact of rutting disease on expressway under heavy traffic is analyzed and the corresponding rut prevention measures and countermeasures are put forward.
