水泥稳定碎石基层具有强度高、承载力大、良好的抗疲劳性能和抗冲刷性等优点,近年来在国道省道公路新改建工程中得到广泛应用,但其易因温度变化和湿度变化产生裂缝并反射到路面,导致路面强度降低,缩短公路使用寿命。笔者根据多年实践经验,对裂缝产生原因进行分析和研究,并提出防治措施。 Cement stabilized macadam base has the advantages of high strength, large bearing capacity, good fatigue resistance and impact resistance. In recent years, it has been widely used in the new reconstruction project of national highway and provincial highway, but it is easy to produce due to temperature changes and humidity changes Cracks and reflected to the road, resulting in reduced road strength and shorten the life of the road. Based on years of practical experience, the author analyzes and studies the causes of cracks and puts forward prevention and control measures.
