210.03.4 Rollers
A.General. Provide rollers and compaction equipment of standard manufacture bearing the manufacturer’s identification label. Roller weight is the manufacturer’s rating. Use self-propelled rollers capable of reversing direction without backlash. Keep rollers in good mechanical condition with positive, accurate steering control. Use adequately powered trucks or tractors for pull-type rollers. Other than traction units, operate rollers separate and distinct from other equipment. Equip all rollers with self-cleaning devices that prevent material from adhering to the wheels or tamping surfaces.
B.Smooth-wheeled Rollers. Use smooth-wheeled, self-propelled rollers meeting one of the following:
1.Tandem type weighing up to 10 tons (9 MT); or
2.Three-wheeled type weighing a minimum 10 tons (9 MT); or
