Asphalt Paving
Our roads and highways are generally coated with asphalt paving material which is spread and leveled to grade.
This is a view of the front of a typical self-propelled, floating screed, paving machine.
Asphalt loaded trucks dump the hot
asphalt into the machines hopper then conveyed to the rear of the machine by a chain and conveyor system.
The paving machine spreads an even layer of asphalt over a layer of compacted road base an a paving mesh or asphalt grid material.
This material help to reinforce the asphalt material and aid in the prevention of cracks. These cracks are often caused by temperature variations and traffic load.
