Background With the increasing number of highway construction and maintenance projects, the types and the quantity of solid wastes generated are great. Such solid waste includes, but is not limited to, asphalt mix waste, concrete waste, rebar waste, plastic waste, and the like. Currently, solid waste management mainly relies on manual classification and simple coding, and the problems of insufficient scientific classification, non-uniform coding, low management efficiency and the like exist, so that the requirements of modern highway engineering on efficient and accurate solid waste management are difficult to meet. In addition, the lack of a classification and grading coding strategy of the system leads to low solid waste recycling rate, serious resource waste and prominent environmental pollution. Therefore, there is a need for a systematic and standardized classification and coding strategy for highway engineering solid wastes to promote the solid waste management level, promote the recycling of resources, and achieve the goal of sustainable development. The solid waste is not classified clearly, the variety of the solid waste is various, the existing classification method is based on experience, systematicness and scientificity are lacked, and the sources and the characteristics of the waste are difficult to comprehensively reflect. In the prior art, the publication No. CN103537470A discloses a solid waste purifying, recycling and reutilizing system, at present, the garbage yield of China is high, the treatment facilities are insufficient, most of the garbage is mainly landfill, incineration and composting, and the garbage is difficult to treat and simultaneously the garbage is extremely wasted. The method mainly depends on a mechanical separation method, but does not establish a refined classification standard based on sources, components, harmfulness and recycling values, is difficult to optimize the treatment method for solid wastes with different properties, does not carry out grading evaluation on key indexes such as density, particle size, harmful substance content, material performance and the like on the solid wastes, cannot provide differentiated treatment suggestions, leads to limited recycling utilization rate, and cannot realize accurate management and traceability of the whole life cycle of the solid wastes.

The method has the advantages that the method can realize classified treatment and utilization of different drilling fluid solid wastes and achieve the purposes of reduction, harmlessness, reclamation and the like of the drilling solid wastes, but the method only aims at the oil-gas drilling solid wastes, does not cover multi-source solid wastes (such as construction wastes, asphalt wastes, soil wastes and the like) generated by highway engineering reconstruction and expansion, cannot meet the solid waste management requirements in the field of highway engineering, only takes the type of a drilling fluid system as a classification basis, does not comprehensively consider multi-dimensional indexes such as harmfulness, recovery value, physicochemical characteristics and the like, and is difficult to realize optimal resource utilization, and the technology provides a combined utilization mode, but does not establish unified classification standards and coding rules, and is difficult to realize systematic management of solid waste data. The first and second existing technologies have the problems of rough classification, classification missing, difficult tracing and the like. Therefore, the invention provides a c
