What is the key technology and structure of modern advanced paver: 1) the full hydraulic independent driving mode of left and right walking crawler. It can realize smooth steering paving and stepless speed change performance. 2) Automatic proportional feeding system. Fully automatic proportional and non-contact sensing control mode, so that the feeding automatically maintains uniformity and stability. Ensure high quality continuous paving operation. 3) High compactness ironing device with various combination forms. At present, there are many combinations of high compactness ironing devices, which adopt different working principles and structures. Fogler recently developed a variety of ironing devices suitable for different working conditions, which is more convenient for users to choose and apply. 4) Combined automatic leveling system. The reference datum is set on paved and unpaved pavement respectively, and the non-contact sensing device is used to effectively improve the paving smoothness and application mobility. 5) All-wheel-driven tire paver. It enhances the adhesion traction, reduces skidding and improves the performance of tire paver.

6. What should we pay attention to when combining the width of the ironing plate?
Answer: When combined ironing plate width, it should also take into account that the longitudinal joint is best located on the longitudinal marking line of the road surface, and try not to set it in the middle of the main lane. When widening the ironing plate, the principle of symmetry should also be obeyed, that is, the combined ironing plate should be as symmetrical as possible to the longitudinal axis of the paver. Otherwise, the paver will be easily deflected due to unequal left and right resistance. In order to maintain its direction along the road, the driver has to operate frequently, which endangers the smoothness of the pavement. In the construction of multi-layer pavement, attention should also be paid to avoid overlap of longitudinal joints between upper and lower layers.
7. There are two conditions for the paver to start?
Answer: The start of the first paving of an asphalt layer and the start of the docking of the already paved layer. The former shall drive the paver to the paving place, and place the front edge of the ironing plate at about 10 cm behind the paving line, and support the ironing plate with at least two boards of the same thickness as the thickness of the layer; the latter shall place the ironing plate on the already paved layer and parallel the front edge of the ironing plate with the interface, and the underlying thickness shall be equal to the difference between the thickness of the loose paving and the compacted thickness of the paved layer.
8. Introduction to ironing device of paver?
The ironing device is the most important and complex working part of the paver. It cooperates with the main machine to complete the paving operation. Its function is to compact and ironing the hot paving material which is transported to the full width of the paving room. The splicing and adjustment of the ironing plate directly affects the paving quality. The ironing device consists of frame, rammer shaft, vibration shaft, heating system, ironing plate, arch adjusting device and covering parts. Hydraulic telescopic ironing plate also has telescopic cylinder and guide cylinder to change paving width. The rammer tampers the paving material to ensure the paving compactness. The paving is ironed flat by an ironing plate. Vibration shaft makes the whole ironing device vibrate slightly to improve the ironing effect. The heating system heats the ironing plate to prevent it from sticking to asphalt. The arch adjusting device adjusts the spreading camber. The rammer shaft is divided into single row and double row. The single row is simple and the double row has high compactness. The rammer shaft is usually at the front end of the ironing plate, and there are pavers that install strong vibration ramming device at the back end of the ironing plate to further ram (e.g. ). The heating system mainly includes gas heating and electric heating.
