Road-building equipment

Contents of city roads - a set of different purposes, labor and methods of operations, among which the most time-consuming and is significant in terms of repair of urban roads in the summer and winter.

Summer cleaning. In the summer harvest contamination is removed from the pavement, seeking to reduce dustiness of the lower layer of the air basin over the roads, the extent of which is determined mainly of dirt, and moisture content of pavement.

It is established that the intensity of the traffic impact on pollution are located on an area of ​​pavement. For example, if the number of vehicles moving on the roadway of the street does not exceed 50-60 units / hr., The pollution are the full width of pavement, and if greater than - that focus on pollution prilotkovoy lane carriageway and the separation zone at a ratio of 1: 2:1.

To determine the scope of sweeping, cleaning and watering, washing machines must take into account the specifics of their work. They sweep and collect pollution in the tank car and taken to clean the streets outside, move the pollution to the curbs, or wash off their flow of water in the storm sewer manholes. When flushing contaminants of the largest components are retained in prilotkovoy band, and storm sewers gets only about 40% of contaminants. Therefore, to remove contaminants accumulated in prilotkovoy and dividing bands, the most convenient sweepers. Watering-washing machines are useful in the streets with storm sewers to the intensity of the movement of vehicles not more than 60 units / hr. (Both sides) in this case, a relatively even distribution of dirt on the roadway such machine washes (cleans) for a pass lane widths up to 8 m

When the normative longitudinal and transverse slope of the road profile contamination remaining in the area prilotkovoy after washing can be washed into wells, or stormwater watering, washing machine, or removed by sweeper-collector.

• The energy balance of machines
  The energy balance of these machines in operation include (depending on the technology works): the cost of power to drive the bitumen pump, defined as vehicles for transporting and distributing bitumen, cost of power to drive the compressor is defined as machines that destroy the hard cover, the cost of power to drive the mixer to be taken when mixing the mastic in the boiler with a capacity of 0.8-1 [...]
• Schebneraspredelitel
  Schebneraspredelitel - frameless design with lifting hopper consists of a hopper, auger metering drum drive mechanism of regulation of seed, wheels with wings, drawbar, the parking support, the site operator, electrical equipment. Bunker - welded, mounted on two wheels, the side walls are attached to the wings and the front - drawbar. On the left side of the hopper is a playground operator, at the bottom [...]
• The third block infrared radiation
  The third block infrared radiation heats the surface and aligns the planned temperature loosened the old material before laying a new layer of the mixture. Inclined conveyor new mixture is fed from the hopper to the height of the chassis frame assembly, where the next conveyor belt transports it in the longitudinal direction of the screw distributor, located behind the rear axle car. Flow control valve for a mixture of - [...]
• Remixer
  Remixer - is, in fact, the car "Repaver", equipped with additional dosing and mixing units. Warmed up the old asphalt coating loosen knives, and then screw valve and located behind the blade is fed into the mixing unit equipped with two shafts. Fresh mix from the hopper conveyor enters the dosing unit, which sends it to the mixer, where the old and the new mass [...]
• Warming unit coating after cleaning the burners
  Repairable coating after it is clean and warm up the block layout of burners: the whole area - the repair of small cards, and on the perimeter of the marked path - in the repair of large maps. After the backwash rakes heated asphalt concrete pavement to a depth of 3-4 cm and supplements in the recommended location of the new material from the hopper, a thermos is a new material is mixed with hot [...]
