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.

在碾壓瀝青混凝土路面時，應根據混合料的攤鋪厚度選擇壓路機的重量、振幅及振動頻率。通常，在鋪層厚度小于60mm的薄鋪層上，使用振幅為0.35-0.60mm的2-6t的小型振動式壓路機，這樣可避免出現堆料、起波和損壞骨料等現象；同時，為了防止瀝青混合料過冷，應在攤鋪之后緊跟著進行碾壓。對于厚度大于100mm的厚鋪層，應使用高振幅（可高達1.0mm）、6-10t的大中型振動式壓路機。

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、對于巖石填方壓實，應選用大噸位壓路機，以便使大型塊料發生位移；

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

2、對于粘土的壓實，使用凸塊搗實式壓路機；

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

3、對于混合料的壓實，選擇振動式壓路機，以便使大小粒料摻和均勻；

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

4、深層壓實宜采用重型振動壓路機慢速碾壓，淺層則應選用靜力作用式壓路機。

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