Description

Technical Field

[0001] The utility model relates to the technical field of cold-mix resin asphalt mixture mixing, in particular to a cold-mix resin asphalt mixture mixing device that can be quickly constructed. Background Art

[0002] Asphalt pavement construction is a crucial step in transportation construction. Hot-mix asphalt is the most common construction method. Typically, hot-mix asphalt is produced and mixed at temperatures exceeding 160°C, and then paved and compacted at temperatures above 120°C. The large amounts of asphalt fumes, dust, heat, and fuel consumed during this process cause significant environmental pollution. To address this, road construction professionals have developed cold-mix resin-based paving technology. Compared to hot-mix asphalt, cold-mix resin-based asphalt is a "green" road construction technology that requires no heating and can be applied at room temperature, offering broad application prospects.

[0003] The binder in cold-mix resin asphalt mixtures is primarily composed of a two-component resin. Once mixed, the two components undergo an irreversible curing reaction, gradually decreasing the workability of the mixture. Therefore, when cold-mix resin asphalt mixtures are mixed far from the construction site, the gradually solidifying binder causes the mixture's workability to decline, hindering subsequent construction. Furthermore, mixing of cold-mix resin asphalt mixtures is currently primarily performed at existing hot-mix asphalt mixing plants, resulting in a cumbersome production process and high energy consumption.

[0004] Given the aforementioned problems with existing cold-mix resin asphalt construction, especially in the production of the mixture, which not only consumes a lot of energy but also compromises the workability of the mixture, a new approach has been proposed to address this situation. This approach aims to create a rapidly constructed cold-mix resin asphalt mixing plant that can be produced on-site, ensuring the mix's workability while reducing production energy consumption. This approach, while achieving green construction, also ensures the mixture's paving quality, and is of great practical significance. Utility Model Content
