[Abstract]:With the rapid development of China's economy, the mileage of highway traffic is increasing. The energy consumption of hot paving asphalt pavement construction is large, if the equipment parameters and construction technology are not reasonable, it will lead to a series of problems such as insufficient energy utilization, serious environmental pollution and so on. Therefore, the research on energy saving construction technology plays an important role in reducing energy consumption in highway construction. Based on the actual situation of energy consumption of high grade pavement construction in China and relying on the construction of Xian-ten-day high speed pavement, this paper studies the construction technology and evaluation method of hot paving asphalt pavement. By studying the dynamic heating process of asphalt tank, the "step dynamic" heating model of asphalt tank is established, and the energy consumption of asphalt heating is reduced. By studying the heating process of drying drum to aggregate, the influence of material blade and driving wheel wear on the formation of material curtain was analyzed, and the factors influencing the heat exchange of material curtain were obtained. The influence of power cycle of double motor mixing equipment on the energy consumption of mixture production is studied, and the method of reducing power cycle is obtained, and the heat preservation and energy saving technology in the process of mixture production and transportation is studied, and the measures for heat preservation and energy saving of asphalt mixture are put forward. According to the working performance of spreading and compacting machinery and the resonance theory of construction machinery and asphalt mixture, the principle of selecting main working parameters of paving and compacting equipment is obtained. The influence of the vibration frequency and spreading speed of paver on initial compaction degree is studied, the reasonable vibration frequency and spreading speed range are determined, the process of following compaction is established, the number of rolling times is reduced, and the working efficiency is improved. The discharge temperature of the mixture is reduced. Based on the analysis of the working principle of infrared imager and electric power detector, the energy consumption detection system is established, and the construction energy consumption model and the total energy consumption calculation model of production, transportation and spreading rolling are established. The evaluation method of energy saving in hot paving asphalt pavement construction is obtained. This study combines theory with practice, and the research results are verified in the construction of Xianteng high-speed pavement, which effectively reduces the construction energy consumption and achieves better energy saving and emission reduction effect.
