Vibratory roller uses its own gravity and vibration to compact various building and road building materials. In highway construction, vibratory roller is widely used because it is suitable for compacting all kinds of non cohesive soil, gravel, gravel mixture and all kinds of asphalt concrete. Next, let's introduce the service conditions of vibratory roller.

在碾压沥青混凝土路面时，应根据混合料的摊铺厚度选择压路机的重量、振幅及振动频率。通常，在铺层厚度小于60mm的薄铺层上，使用振幅为0.35-0.60mm的2-6t的小型振动式压路机，这样可避免出现堆料、起波和损坏骨料等现象；同时，为了防止沥青混合料过冷，应在摊铺之后紧跟着进行碾压。对于厚度大于100mm的厚铺层，应使用高振幅（可高达1.0mm）、6-10t的大中型振动式压路机。

When rolling the asphalt concrete pavement, the weight, amplitude and vibration frequency of the roller shall be selected according to the paving thickness of the mixture. Generally, a small vibratory roller of 2-6t with an amplitude of 0.35-0.60mm is used on a thin pavement with a pavement thickness of less than 60mm, so as to avoid stacking, wave and damage to aggregate; Meanwhile, in order to prevent the asphalt mixture from being too cold, it shall be rolled immediately after paving. For thick layers with thickness greater than 100mm, large and medium-sized vibratory rollers with high amplitude (up to 1.0mm) and 6-10t shall be used.

1、对于岩石填方压实，应选用大吨位压路机，以便使大型块料发生位移；

1. For rock filling and compaction, large tonnage roller shall be selected to displace large blocks;

2、对于粘土的压实，使用凸块捣实式压路机；

2. For the compaction of clay, use bump tamping roller;

3、对于混合料的压实，选择振动式压路机，以便使大小粒料掺和均匀；

3. For the compaction of the mixture, the vibratory roller shall be selected to mix the large and small aggregates evenly;

4、深层压实宜采用重型振动压路机慢速碾压，浅层则应选用静力作用式压路机。

4. Heavy vibratory roller shall be used for slow compaction in deep layer, and static roller shall be used in shallow layer.
