I. Introduction.
With the rapid development of China's economy and the growing demand for infrastructure construction, asphalt surface course engineering is an important part of road construction, and its cost control has become a key link in project management. This paper analyzes the costs of asphalt surface course engineering and proposes corresponding control strategies, in order to provide reference for project managers.
Second, asphalt surface course engineering cost analysis.
1.Cleaning the lower bearing layer: 01~0.$15
Cleaning the lower bearing layer is the basic work to ensure the quality of the asphalt surface course, and its cost is relatively low, but it cannot be ignored. In the actual construction process, cleaning should be carried out in strict accordance with the design requirements to avoid project quality problems caused by incomplete cleaning.
2.Milling old pavement: 50 80 yuan m
Milling old pavement is an important part of asphalt surface course engineering, and its cost is affected by factors such as milling equipment and milling thickness. In order to reduce costs, milling equipment should be reasonably selected to improve milling efficiency and reduce milling thickness.
3.Permeable layer, adhesive layer, slurry sealing layer: 004~0.06 yuan03~0.05 yuan$3
Permeable layer, adhesive layer and slurry sealing layer are the key links of asphalt surface course engineering, and their cost is relatively low, but it has a significant impact on the quality of the project. In the actual construction process, appropriate materials should be selected and the construction quality should be strictly controlled to ensure the project effect.
4.Asphalt debarreling, emulsified asphalt configuration: 80 100 yuan t, 6 66 yuan t
Asphalt debarreling and emulsified asphalt configuration are important aspects of asphalt surface course engineering, and their cost is affected by asphalt raw materials, equipment performance and other factors. In order to reduce costs, asphalt raw materials should be reasonably selected to improve equipment utilization.
5.Asphalt mixture mixing, transportation, paving compaction: 40 47 yuan t, 08~0.$9 tkm, 12 13 yuan t
Asphalt mixture, transportation and paving compaction are the core links of asphalt surface course engineering, and its cost is affected by factors such as raw materials, transportation distance, and equipment performance. In order to reduce costs, raw materials should be reasonably selected, transportation routes should be optimized, and equipment utilization should be improved.
6.Cement concrete pavement, curb, middle zone fill, shoulder soil: 60 70 yuan m 20 yuan m, 7 8 yuan m 8 yuan m
Cement concrete pavement, curb, middle zone fill and shoulder soil are ancillary works of asphalt surface course engineering, and their cost is relatively low, but they play an important role in the overall quality and aesthetics of the road. In the actual construction process, the construction quality should be strictly controlled to ensure that the ancillary projects and the main project are coordinated.
7.D600 socket reinforced concrete pipe, pipeline concrete flat foundation and cushion concrete, pipeline concrete pipe seat: 40 50 yuan m, 40 50 yuan m 90 yuan m
D600 socket reinforced concrete pipe, pipeline concrete flat foundation and cushion concrete and pipeline concrete seat are an important part of asphalt surface course engineering, and their cost is affected by factors such as raw materials and equipment performance. In order to reduce costs, raw materials should be reasonably selected to improve equipment utilization.
Third, asphalt surface course engineering cost control strategy.
1.Optimize engineering design: In the design stage, fully consider the actual situation of the project, reasonably select the construction plan and materials, and reduce the project cost.
2.Strengthen material management: strengthen the management of raw material procurement, transportation, storage and other links to reduce material costs.
3.Improve construction efficiency: reasonably arrange the construction schedule, improve the utilization rate of equipment, and reduce construction costs.
4.Strict control of project quality: strengthen quality control in the construction process to reduce rework and maintenance costs.
5.Strengthen safe and civilized construction: improve the degree of safety and civilization on the construction site, and reduce the additional costs caused by safety accidents and environmental pollution.
6.Training of professionals: improve the professional quality of engineering management personnel and reduce management costs.
IV. Conclusions. Asphalt surface course engineering cost control is an important part of project management, through the optimization of engineering design, strengthen material management, improve construction efficiency, strict control of project quality, strengthen safe and civilized construction and training professionals and other strategies, can effectively reduce the cost of the project, improve the efficiency of the project. In the actual project management process, the cost control strategy should be flexibly used according to the actual situation of the project to achieve the optimization of the project cost. construction site
