Asphalt equipment mainly includes asphalt concrete mixing equipment and asphalt concrete paving machine.
Asphalt concrete mixing equipment is a device that dries, heats, screens, and measures gravel, adds an appropriate amount of filler (such as stone powder), and mixes it with hot asphalt liquid in a certain proportion to form an asphalt mixture. The production process is automatically controlled by a computer to improve the mixing process, reduce fuel consumption, and reduce exhaust gas and dust pollution. Common asphalt mixing equipment is divided into mobile double-drum SLB series, mobile forced QLB series, and finished product bin bottom-mounted GLB series. These equipment have different design features, such as the double-drum design is simple and easy to operate, while the forced type is more thoroughly mixed and the quality of the finished product is more stable.
Asphalt concrete paving machine, also known as asphalt concrete paver, is a machine specially used for asphalt pavement construction. Its main function is to evenly spread the mixed asphalt concrete material on the road subbase or base, and to perform a certain degree of pre-compaction and shaping to ensure the thickness, width, road camber, flatness and density of the paving layer. Paving machines are widely used in asphalt concrete paving operations in highways, urban roads, large freight yards, parking lots, docks and airports.
With the development of hydraulic technology, electronic technology, sensor technology, control theory and computer control technology, the performance of asphalt equipment has been further improved, the structure has become more scientific and reasonable, and the operation has become easier.
