(1) Whether it is up or down the slope, the asphalt mixture must be clean and dry, and must be sprayed with asphalt bonding layer, in order to avoid the mixture in the rolling slip.
Whether it is uphill or downhill rolling, the driving wheel of the roller should be in the back. This has the following advantages: uphill, behind the driving wheel can withstand the driving force provided by the ramp and the machine itself, while the front wheel on the road for preliminary compaction, in order to withstand the larger shear force generated by the driving wheel; When going downhill, the impact force generated by the roller's weight is offset by the braking of the driving wheel. Only the mixture after the front wheel is crushed can support the driving wheel to produce shear force.
