Asphalt pavement construction involves a variety of mechanical equipment, each machinery has different functions. The following are the common asphalt pavement construction machinery and their functions.
Vibrating roller: Used for the primary compaction and final compaction of the asphalt pavement, to ensure the uniform and compaction of the road surface, and to improve the bearing capacity and durability of the road surface.
Asphalt paver: Used to evenly lay the hot asphalt mixture on the road surface, and has the function of adjusting the thickness and width of the laying. The paver usually includes parts such as feeder, paving roller and vibration system.
Asphalt mixer: used for mixing and stirring asphalt mixture ( asphalt, aggregate and filler, etc.), to ensure the uniformity and quality of the mixture, and provide for paver.
Asphalt heating equipment: heat the asphalt material to the required construction temperature to ensure that the hot asphalt can be laid smoothly on the paver.
The hardening agent spraying vehicle: used to spray the stabilizer or asphalt emulsion to improve the water resistance and crack resistance of the road surface, and strengthen the combination of the road surface and the base.
Asphalt recovery machine: in the repair and maintenance process of road surface pavement, it is used for recycling and reuse of old asphalt materials to reduce the waste of resources and environmental pollution.
Pavement milling machine: used to remove the damaged part of the old asphalt pavement, improve the smoothness and adjust the pavement height to prepare for the new asphalt paving.
Flexible guardrail equipment: used to set up the guardrail at the road edge to provide traffic safety protection.
Road marking machine: used to draw road marking and traffic signs to guide vehicles and improve traffic safety.
Overall, these asphalt mechanical equipment play an important role in the construction process of road pavement, to ensure the smoothness, durability, comfort and safety of the pavement. Construction personnel nedd to be familiar with the operation and maintenance methods of each mechanical equipment to ensure the construction quality and engineering efficiency.
