Abstract

It is found that the construction and energy consumption of asphalt pavement mainly focus on the production of asphalt raw materials and asphalt mixture. According to the characteristics of project construction, this paper adopts professional environmental protection technology to carry out full-node and continuous tracking monitoring on the two links of asphalt mixture production and pavement construction, combined with the construction site environment. The energy consumption and emission of aggregate heating process and materials in mixing station were monitored and studied. It is committed to standardize the energy saving evaluation and technical optimization of the expressway reconstruction and expansion technology in Shandong, so that the evaluation work can be based on evidence. The qualitative or quantitative research is mainly carried out from the technology of warm mixing asphalt, aggregate heating and asphalt heating process improvement. By studying the composition of energy consumption, the influencing factors of energy consumption, the calculation method of energy consumption, the unit energy consumption of each energy consumption item and the level of energy consumption, a perfect evaluation system and effective and feasible energy-saving measures are proposed, and an energy-saving evaluation system for highway reconstruction and expansion in Shandong Province is researched and developed.
