The construction method also varies as per material used. For instance, to use asphalt for constructing a curb, a paving machine is required. Though it works out to be less expensive if it is formed at the time of road pavement, it is likely to have lower durability as compared to a concrete curb.
An asphalt paver is a machine used to distribute, shape, and partially compact a layer of asphalt on the surface of a roadway, parking lot, or other area. It is sometimes called an asphalt-paving machine. Some pavers are towed by the dump truck delivering the asphalt, but most are self-propelled.

the paving site where it is spread to a uniform thickness with a mechanical paving or finish-ing machine. Then the material is compacted to the required degree by heavy, self-propelled rollers, producing a smooth, well-compacted pavement course. The paving or finishing machine places the Asphalt Concrete at temperatures above 225¡ F.

NZP168 Retractable Concrete Paver Machine has the function of Paving, vibrating, Leveling and making small radians of road surface. So it is very suitable for concrete road paving, concrete surface layer of bridges, highway, municipal roads, squares, airport runways and other concrete construction.
This is what a highway paving machine looked like at the turn of the 20th century: It stood just under six feet tall with a strong back, sturdy biceps and well-muscled legs.
An asphalt paver can be on tracks or on tires: wheeled pavers are mainly used in town, while tracked pavers are preferred for major works (highways). An operator controls the machine from the control platform. The asphalt paver progresses slowly, and can spread between 600 and 1,100 t / h over a width of 1.2 to 14 meters.
Asphalt pavers are the key machines in any paving operation. It is important to understand these machines before making a rental decision. First, the paver funnels hot mix asphalt (HMA) to the rear of the machine through the use of flight feeders and augers. The HMA then travels into the screed.
Concrete pavers encompass a range of types, including form-riding paving machines, curb-and-gutter machines, and slipform machines. Form-riding pavers ride on metal forms that set the boundaries of the paved surface; a typical application for these machines is bridge-deck paving, and the machine typically employs rollers that move transversely ...

The asphalt paver is a self-propelled formless laydown machine with a floating screed. HMA is loaded in the front, carried to the rear by a set of flight feeders (conveyor belts), spread out by a set of augers, then leveled and compacted by a screed. This set of functions can be divided into two main systems:
The breakdown roller should be right behind the paving machine. Finish rolling should be complete before the pavement temp. reaches 150 degrees. g. Air temp. should be at least 40 °F for base lift and 50 °F for surface lift. Open graded AC should only be placed when the air temp is 70 °F. 2.
