| 摘要: |
| 为改善沥青路面施工过程能耗高的问题,采用振动压路机进行沥青混合料压实试验,得到了混合料压实度与碾压遍数之间关系；采用摊铺机进行混合料摊铺试验,得到了混合料摊铺压实度与振动频率之间关系；基于以上研究,建立了压路机数量计算模型、摊铺机作业功率计算模型和压路机作业功率计算模型,进而建立了与摊铺压实度相关的摊铺碾压总体能耗计算模型。进行模型分析表明,通过调节摊铺机的振动频率,可以得到高密实混合料摊铺层,此时摊铺机的功率消耗增加很小,但是可以大幅减少压路机的碾压工作量,显著降低摊铺碾压过程的总体能耗。通过实体工程试验,结果表明:采用所提出的摊铺碾压节能技术,将摊铺机的振动频率从10 Hz提高到35 Hz,可将混合料的摊铺压实度从0.800提高到0.901,摊铺压实作业过程设备的总能耗可降低30.4%,具有显著的节能减排效果。 |

| Abstract: |
| 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. |
