(3) When rolling uphill, the roller should start, stop and accelerate smoothly to avoid too high or too low speed.
(4) Before the up-slope rolling, the mixture should be cooled to the specified low limit temperature, and then the static prepressure should be carried out. When the temperature of the mixture drops to the lower limit (120℃), the vibration compaction should be used.
⑤ Downhill rolling should avoid sudden speed change and braking.
(6) In the case of steep slope rolling, the first use of light roller precompaction, and then use heavy roller or vibratory roller compaction.
