If the provision of design elevations solved mainly by providing elevation of subgrade and base, all other requirements must provide asphalt. Modern Pavers have a hydrostatic travel drive and all working parts are equipped with automatic regulation of screed vertical (from a standard or a mobile copier and sensor of surface laid adjacent lanes) and the cross-slope (cross slope of the sensor). By type undercarriage pavers share on tracked and wheeled. Tracked Pavers – a machine for construction and reconstruction of roads, streets and airfields with asphalt coating. Wheeled Pavers are produced mainly 3 – and 4-axis: one or two rear axles with Pneumatic and two axles with rubber wheels located under the lateral otkrylkami hopper. I wheeled paver drive can only be done on pnevmokolesa, and maybe on all axes, which improves traction and stability of their machines progress. Practical Application of wheeled paver has shown that this machine for laying the upper (thin) coating layer, as well as for the repair of the pavement by laying an additional top layer of asphalt. Especially beneficial in the repair of wheeled pavers cover the way in laying a mixture of individual pickets and repair charts, as moving quickly from one place to another installation, do not require the use of trailers required for movements tracked asphalt pavers, as well as provide significantly higher levels of evenness, the cross slope and thickness of the coating compared to manual laying (distribution) of the mixture.
A special place among asphalt pavers bands occupy alloy broadening, were developed in the U.S In Europe, these works are carried out using mini stackers on crawlers. In general, the market advanced security asphalt is very wide and gives consumers (road organizations) the possibility of selection of machines for the most complex objects and construction conditions, including the ability to change the width of the stacking process production work, the use of sliding and composite working bodies, including the working bodies of the high-compaction. In recent years, thanks to the optimum ratio of price and quality, increasingly used in Russia pavers are made in China. With all the variety of Chinese manufacturers is a good choice products concern xcmg. This product meets all international quality standards, making machinery xcmg is widespread in almost all continents of the world.
