Asphalt spreader is a kind of engineering vehicle specially used for spraying asphalt, mainly used for road
construction and maintenance. It is usually equipped with bitumen storage tanks, heating systems and
spraying devices that can evenly spray liquid bitumen on the road surface to provide good road adhesion
and water resistance.
The tank of the asphalt spreader is generally large in capacity and can load enough asphalt to meet the
needs of long-distance construction. The heating system heats the asphalt to the right temperature so that
it remains liquid and easy to spray. The spraying device usually includes a sprinkler head and a control
system that can adjust the width, thickness and speed of the spray according to the construction requirements.
Asphalt spreader plays an important role in road construction. It can be used for surface treatment of new
roads, such as spraying bonding layer asphalt to enhance the adhesion between the road surface and the
base. In road maintenance, asphalt spreader can also be used to repair road cracks, fill potholes, etc., to
extend the service life of the road.
In addition, the operation of the asphalt spreader requires professional skills and experience. Operators
need to understand the characteristics of asphalt, construction requirements and safety precautions to
ensure construction quality and operation safety. At the same time, in order to protect the environment, the
asphalt spreader also needs to be equipped with appropriate pollution control equipment to reduce the
impact of asphalt spraying on the surrounding environment.
Overall, asphalt spreader is an indispensable tool in road construction and maintenance, and its use can
improve construction efficiency and road quality.
