ABSTRACT
To continuously promote the sustainable development of highway maintenance management, based on the cost analysis of the whole construction process and each stage of cold central plant recycling, this paper establishes the framework and processes of economic benefits evaluation, clarifies the different economic benefits performance of cold central plant recycling method in comparison with traditional maintenance method, and explores the key influencing factors of economic benefits and improvement countermeasures by using sensitivity analysis method. Finally, according to the calculation, this paper puts forward some countermeasures and suggestions to further improve the economic benefits of cold central plant recycling technology from the reasonable control of emulsified asphalt consumption, optimizing the layout and construction of the mixing plant, and establishing the economic benefits evaluation mechanism.
