不同压路机在沥青路面的应用
来源：/ 日期：2023-05-22
一般在现场，我们为了压实时沥青混合料要一直保持较高的温度，目的是为了保证压实后达到密度的要求。常规上分类，压路机主要有三种：钢轮压路机、胶轮压路机和振动式钢轮压路机。而目前后面的两种压路机在施工中运用的比较多一些。
Generally, on site, we maintain a high temperature of the asphalt mixture during compaction to ensure that it meets the density requirements after compaction. Traditionally, there are three main types of rollers: steel wheeled rollers, rubber wheeled rollers, and vibrating steel wheeled rollers. At present, the latter two types of rollers are more commonly used in construction.
济南压路机出租人员提醒您，压路机的主要目的有两个：一是为了达到规定的密度要求；二是压出整平的路面。而压实总共包括初压，复压和终压三种形式。
Jinan roller rental personnel remind you that the main purposes of rollers are twofold: firstly, to meet the specified density requirements; The second is to press out the leveled road surface. And compaction includes three forms: initial compaction, re compaction, and final compaction.
为了去除压路机的痕迹，是路面保持平整，不能忽略的一步，并且是采用钢轮压路机。当然，要是初压可以满足密度要求，就不需要复压了，不过实际在现场，绝大部分情况还是保持着这三步。
In order to remove the traces of the roller, it is a step that cannot be ignored to maintain a smooth road surface, and a steel wheeled roller is used. Of course, if the initial compaction can meet the density requirements, there is no need for re compaction, but in reality, in most cases, these three steps are still maintained on site.
初压一般用钢轮压路机，但会出现推移现象，即滚筒前侧的混合料受压力进行横向移动，在压实后有可能产生裂缝。
Steel wheel rollers are generally used for initial compaction, but there may be displacement, where the mixture on the front side of the drum moves laterally under pressure, which may cause cracks after compaction.
也有用胶轮进行初压的，但因为初压时温度较高，混合料容易粘附在轮胎上，而且留下的痕迹不容易去除，所以胶轮进行复压的机会比较多。
Rubber wheels are also used for initial pressure, but due to the high temperature during initial pressure, the mixture is easy to adhere to the tire and the traces left are not easy to remove, so there are more opportunities for rubber wheels to be re pressed.
此外要了解一些注意事项，比如：
In addition, it is important to understand some precautions, such as:
在进行路面作业时，压路机前后轮的刮板，应保持平整良好。碾轮洒水机刮泥人员应与操作手密切配合，必须跟在碾压轮行走的后方，要注意压路机转向。
When carrying out road surface operations, the scrapers on the front and rear wheels of the roller should be kept flat and in good condition. The scraping personnel of the roller sprinkler should closely cooperate with the operator and must follow behind the roller when walking. Attention should be paid to the turning direction of the roller.
在改变行驶方向、减速或停驶前应先停止振动。起振和停振必须在压路机行走时进行；在坚硬路面行走时候严禁振动。碾压松软路基。
Stop the vibration before changing the direction of travel, slowing down, or stopping. Starting and stopping vibration must be carried out while the roller is running; Vibration is strictly prohibited when walking on hard roads. Rolling the soft roadbed.
应先在不振动的情况下碾压1-2遍，然后再振动碾压。换向离合器、起振离合器和制动器的调整，必须在主离合器脱开后进行，不得在急转弯时用快速档；严禁在尚未起振情况下调节振动频率。
Rolling should be carried out 1-2 times without vibration, followed by vibration rolling. The adjustment of the reversing clutch, starting clutch, and brake must be carried out after the main clutch is disengaged, and fast gear cannot be used during sharp turns; It is strictly prohibited to adjust the vibration frequency before the vibration has started.
Roller operators must fully consider the blind corners of the machine's line of sight, and strictly prohibit driving the machine with blind or lucky mentality. If there is anything else you don't understand, feel free to consult us at any time ！
