Abstract

The invention discloses an abandoned thermosetting plastic modified asphalt and a modified asphalt mixture. The modified asphalt mixture is prepared by adding abandoned thermosetting plastic to asphalt; the particle sizes of the abandoned thermosetting plastic are smaller than or equal to 0.15mm; the abandoned thermosetting plastic is one or more of abandoned phenolic plastic, amino plastic, urea formaldehyde, melamine, epoxy resin, furan resin, unsaturated polyester resin and silicon resin. By adopting the characteristics that the abandoned thermosetting plastic has certain compatibility with the asphalt, the abandoned thermosetting plastic is processed into granules of which the sizes are close to the particle sizes of mineral powder and fine aggregates, so that partial mineral powder, fine aggregates and asphalt can be replaced with the abandoned thermosetting plastic; the wastes are fully reutilized; the environment pollution is reduced; the resources and the costs are reduced; the properties such as high temperature and strength of the asphalt and the asphalt mixture are improved.

Description

technical field

[0001] The invention belongs to the technical field of road engineering and environmental protection, and in particular relates to a waste thermosetting plastic modified asphalt and a modified asphalt mixture. Background technique

[0002] As a high-strength, high-temperature-resistant, and insoluble material, thermosetting plastics have been used in various fields of society. However, under existing technical conditions, it is difficult to recycle thermosetting plastics once they are discarded, especially on a large scale. Generally, what we call plastic recycling refers to thermoplastics, and thermosetting plastics form a cross-linked structure after solidification and molding, and cannot be melted and molded again, so recycling is more difficult, and actual recycling applications are seldom. Only polyurethane etc. are recycled commercially on a small scale. The amount of thermosetting plastics accounts for about 15% of all plastics, and the absolute amoun...
