在沥青路面的压实作业中,为了使道路达到最佳密实度,除了要根据不同的工况选择适宜的压路机外,在碾压过程中还要控制以下五个因素:1)压路机速度,2)压路机碾压的次数,3)碾压温度时区,4)压路机的碾压方法,5)振动频率和振幅。充分注意了这些因素,不仅可以提高生产率,同时还可保证路面具有良好的使用性能。一、碾压沥青道路的基本原则1.在开始第一遍碾压过程中,要注意检查混和料的温度,最佳碾压温度时区是在120～150℃之间。若碾压温度过高则会出现:(1)材料沿滚
In compaction of asphalt pavement, in order to make the road to achieve the best density, in addition to select the appropriate roller according to different working conditions, the following five factors are also controlled in the rolling process: 1) roller speed, 2 ) The number of roller compaction, 3) rolling temperature time zone, 4) roller compaction method, 5) vibration frequency and amplitude. Full attention to these factors, not only can improve productivity, but also ensure that the pavement has good performance. First, the basic principles of rolling asphalt road 1. At the beginning of the first pass rolling process, we should pay attention to check the temperature of the mixture, the best rolling temperature time zone is between 120 ~ 150 ℃. If the rolling temperature is too high will appear: (1) material along the roll
