Pavement maintenance is a systematic project, in the process of configuration maintenance machinery should establish a systematic idea, to comply with the principle of the system. That must be from the overall situation of the whole road maintenance operations, the development of maintenance machinery configuration program, in order to maintain the overall goal of the operating system as a basis for. In addition, we should also pay attention to the following three principles:
(1) the applicability of the project
In the selection process to be based on the need to maintain the road conditions and the working environment to select a reasonable mechanical. For example, in this discussion is the maintenance of asphalt pavement, then the choice of equipment must be mainly for asphalt pavement service. In addition, China's vast territory, geographical and climatic conditions change, the selection of the full consideration should be made.
(2) the advanced nature of Technology
A performance and technology are very advanced equipment, its production capacity several times in a relatively backward model. Selection of advanced equipment, high production efficiency, low failure rate, the need for manual maintenance of less time, the quality of work is generally guaranteed.
(3) economic rationality
In the selection of mechanical process, according to their economic capacity, priority allocation of some of the maintenance work more prominent equipment, then according to the finances of the units themselves constantly updated, gradually improve the equipment level. At the same time, we should consider the technical level of workers in this unit, in order to avoid the purchase of expensive equipment, no one can control, resulting in waste of resources, increase the cost of maintenance projects.
