Asphalt is a petroleum by product that is used to form a mixture that solidifies into a compact hard wearing material that is used to cover roads and other areas. This is facilitated by heating the asphalt and mixing it with stone aggregates. The asphalt binds the aggregates together to form the top surface of roads.
While in earlier days asphalt was heated in drums or pits to which the aggregates were added and mixed by hand, it is customary nowadays to use an asphalt mixing plant (асфальтовый завод) to achieve the same mixture that is then conveyed to the site where it is required in suitable tankers or containers that are also heated, and then laid in layers on the site by spreading it by hand or by special spreading equipment that controls the thickness of the layer.
What are the advantages of using an asphalt mixing plant? It can help to save a lot of time and labor, so that the work of laying the asphalt can be completed in a controlled and continuous manner. These asphalt plants can be portable, and this makes then far more useful, as they can be moved close to the site where the asphalt mix is required, resulting in a saving of transportation costs, as well as allowing the mixed material to remain at just the right temperature needed for ensuring its quality. This helps also to reduce the traffic on roads that the heavy slow moving trucks that carry asphalt can cause.
Most asphalt mixing plants (асфальтные заводы) have weighing mechanisms that enable the aggregate and asphalt to be conveyed to the mixing drum in the proportions given by the design engineers. These proportions by weight give better quality of asphalt than the volumetric means often used during hand mixing. These proportions are based on the strength of the stone from which aggregates are made, the quality and temperature of asphalt and other factors. The plant also has a mixing drum in which all these materials, asphalt and aggregates are mixed for a fixed period of time, that ensures that all aggregates are equally coated with the asphalt to ensure their proper binding. The plants also have heaters that bring the asphalt to the proper temperature before it is released into the mixing drum.
An asphalt mixing plant enables the production of hot mix asphalt to the specifications of each project or client, and allows for changes in aggregate weights, temperatures required,and other needed parameters. Every plant will have its own capacity that can vary as per the quantity of asphalt required per day. Every plant comes with a feeding unit that also screens and conveys the aggregates, a drying drum equipped with burners, hot bins, bitumen tanks, hot oil heaters, storage silos for the aggregates, and a proper control panel that allows for easy operations of all its functions from a central point.

Asphalt mixing plants do not require a lot of manpower, while they greatly improve on quality and output. This factor in the long run can greatly reduce costs of paving works. Most plants carry manufacturers guarantees for their equipment. If you want to buy asphalt mixing plants, Aimix Group China is a good choice.
