To solve the problem of high energy consumption during asphalt pavement construction

compaction tests were conducted using a vibratory roller on an asphalt mixture

and the relationship between the degree of compaction and the number of rolling passes was obtained. Asphalt paving tests were conducted on the mixture with a paver

and the relationship between the degree of compaction during paving and the vibration frequency of the paver was identified. Based on the above research findings

calculation models were developed to determine the number of rollers

the working power of the paver and the roller

and the overall energy consumption of paving and rolling process related to the compaction degree of paving. The model analysis shows that the high density of asphalt mixture paving layer can be achieved by adjusting vibration frequency of the paver. The power consumption of the paver is slightly increased

yet the rolling workload of rollers can be greatly reduced

thereby significantly reducing the overall energy consumption. The results show that by using the proposed energy-saving technology

the vibration frequency of the paver is increased from 10 Hz to 35 Hz

with the compaction degree of paving increased from 0.800 to 0.901

and the total energy consumption of the paving and rolling process reduced by 30.4%

producing a significant effect on energy saving and emission reduction.
