Choose according to the type (grade) of the road: For the first- and second-level national trunk roads and special roads for automobiles, large vibratory rollers with a high compaction capacity of 6 to 10 tons should be used; For roads below the third level, or infrequent compaction. In actual operation, it is best to equip about 2t of mobile and flexible vibration roller. For cement concrete pavement, a tire-driven series vibratory roller can be used; for asphalt concrete pavement, a fully-driven vibratory roller should be used;
For the bottom layer of high-grade pavement roadbeds, it is best to use tire rollers or tire-driven vibratory rollers for compaction to obtain a uniform density; static-acting light-wheel rollers can be used when repairing the road surface.
Choose according to the type of material being compacted: For rock fill compaction, a large-tonnage roller should be used to displace large blocks; for clay compaction, it is best to use a bump compactor roller; for mixture compaction. In fact, it is best to choose a vibratory roller in order to blend the large and small particles uniformly; for deep lamination, heavy-duty vibratory rollers should be used for slow rolling, and for shallow layers, static-action rollers should be used.
