Asphalt equipment mainly includes the following categories:
Emulsified asphalt equipment: This equipment is used to heat melt asphalt and break it into tiny particles through mechanical force, and evenly disperse it in water to form an emulsion, namely emulsified asphalt. Emulsified asphalt is mainly used as a permeable layer, bonding layer and surface layer binder in highway and urban road projects, and is also suitable for the preparation of waterproof coatings and waterproof membranes in the construction industry1.
Asphalt spreader: This is an early road engineering machinery used to transport and spray various liquid asphalts (including hot asphalt, emulsified asphalt and residual oil, etc.). Asphalt spreaders can also be used to spray asphalt binders on locally crushed soil to build stabilized soil pavement. In addition, it can also be used as a carrier for asphalt and emulsified asphalt2.
Asphalt mixing equipment: This equipment is used to produce asphalt mixtures, usually consisting of a cold material supply system, a drying and heating system, a hot material lifting and screening system, an asphalt supply system, a mixing system, and a finished material storage and transportation system. By precisely controlling the proportion and mixing process of raw materials, asphalt mixtures that meet engineering requirements are produced, which are widely used in road paving in places such as highways, urban roads, airport runways, and parking lots. 3.
Asphalt paver: This equipment is used to evenly spread asphalt mixtures on the road base, and perform preliminary vibration and leveling. It is widely used in asphalt paving operations such as urban roads, highways, docks, and large parking lots. 4.
Asphalt concrete paver: This machine is used to evenly spread asphalt mixtures on the road base, and perform preliminary vibration and leveling. Pavers are divided into crawler type and tire type. The former includes a frame, a power unit, a walking device, etc., and the latter includes a traction arm, a vibration mechanism, and a smoothing device, etc. 5.
These equipment play an important role in road construction and together ensure high-quality and efficient construction.
