Wearing out over time, any road surface not only causes discomfort to road users, but also becomes a threat to their safety. For various road construction or repair work, special equipment is used, which includes a road mill.
This equipment is designed to eliminate the asphalt concrete layer by loosening and grinding. The use of such special equipment allows you to perform work quickly and efficiently. A road milling machine removes a worn layer of a paving layer by layer, removes various defects - cracks, knolls or potholes, forms a longitudinal / transverse profile of asphalt concrete.
Road milling machine - an integral tool in the arsenal of road-building equipment. Repair and construction work on roads, bridges, squares, when laying communication lines or over the emergency section of the pipeline practically does not do without the use of such equipment. Using this technique, floor leveling is possible in industrial halls or warehouses.
Modern models of machines are a combine with a milling drum, which is located between the four drive tracks. Rotating, the drum, equipped with cutters, is immersed in the pavement to the required depth, destroying and removing it layer by layer. Each piece of equipment has containers for collecting the removed material (they are suitable for secondary use) and a conveyor designed for loading the milled asphalt concrete pavement into the back of another vehicle.
Road milling machines, according to the accepted classification, are divided into two types:
- Caterpillar models of equipment are usually operated on highways. They are distinguished by their heavy construction. The width of the drum is 1500-2100 mm, and the maximum depth for milling is 32 cm.
- Wheel mills, due to their compact size, can be used in a limited space and are suitable for work on sidewalks, houses and other confined spaces. The drum width for these machines is much smaller than for tracked ones - from 500 to 1500 mm.
Universal equipment such as a road-ice milling cutter is used not only in winter to clean roads from ice and a packed snow layer, but also in summer, during restoration work on gravel or dirt roads or to eliminate the effects of spring thaw.
A convenient control system allows you to carry out repair work with high accuracy, accurately cutting worn asphalt concrete pavement even in hard-to-reach places - near curbs or walls. The road milling machine is characterized by high performance, ease of use and reliability. Modern and efficient road equipment has a wide range. The most popular brands of this special equipment include the following: Wirtgen, Volvo, Bitelli, Cartepillar, Raiko - these companies, constantly working on improving the manufactured equipment, offer innovative solutions.
