Choose according to engineering quality requirements: if you want to obtain a uniform compaction density, you can choose a tire roller. The tire-type roller does not destroy the original viscosity of the soil during rolling, and has good bonding properties between each layer of soil. The front wheel can swing, so the compaction is more uniform and there will be no false compaction. If you want to make the road compact, the full-drive roller can be used. For areas where the compaction capacity of the roller is not high, a roller with low line pressure and flexible maneuverability can be used. To achieve the compaction effect as soon as possible, a large-tonnage roller can be used to shorten the construction period.
Selection according to the thickness of the pavement: When rolling the asphalt concrete pavement, the weight, amplitude and vibration frequency of the roller should be selected according to the paving thickness of the mixture. In general, on thin pavements with a thickness of less than 60mm, it is best to use 2~6t small vibratory rollers with an amplitude of 0.35~0.60mm, so as to avoid the phenomenon of stacking, undulation and damage to the aggregate; at the same time In order to prevent the asphalt mixture from being too cold, it should be rolled immediately after paving. For thick layers with a thickness greater than 100mm, large and medium-sized vibratory rollers with high amplitude (up to 1.0mm) and 6~10t should be used.Vibratory Roller
