Road repair is a burning topic that hurts absolutely everyone. Drivers complain about the disgusting cover that ultimately cripples their cars ahead of time. Passengers of public transport - on the quality of transportation and violation of the schedule. Officials - on the lack of funding, which is why it is impossible to carry out high-quality repair work.
You can search for the guilty for a long time or try to find an economical and effective solution to the problem. A step forward in resolving this situation will be the use of recycled materials, namely the laying of asphalt crumbs.
What is asphalt crumb suitable for?
Roads at all levels are in distress - from federal highways where replacement of the coating is necessary to local routes. The latter often remain deprived of the attention of the authorities and over the years become completely unsuitable for traffic.
Recycled materials obtained after processing old asphalt are a universal resource for the construction of highways. The technology of laying asphalt crumbs allows you to solve a number of problems, spending a minimum of money. Ground asphalt is suitable both for the construction of new modern roads and for filling roads with a low traffic load.
Specifications
Making asphalt crumb is a simple process, and in operation it shows itself better than crushed stone. Such raw materials retain all the driving characteristics of the asphalt pavement. Mechanical grinding of large strata does not affect the fact that bitumen is present in the composition - the substance is simultaneously astringent and creates additional density. This significantly extends the life of the road.
Another plus of laying asphalt crumb is that over time, the quality of the road only improves: fragments of the old pavement are crushed and pressed so that a fairly even and durable coating is obtained. This makes asphalt crumb a real panacea for villages, country cooperatives and other places where new roads will not be built in the foreseeable future.
Paving asphalt crumb yourself
The indisputable advantage of this raw material is that it does not require special qualifications to work with it. The product of the processing of removed asphalt every day becomes more and more popular material. The popularity of raw materials is added by the fact that it became possible to lay asphalt crumb with your own hands.
If we are talking about a small area and there are no time limits, then even one person can cope with such a task. In the case of a large area, it is better to hire a team of workers.
Work order
So, the builder’s qualifications for laying asphalt crumbs are not needed. All you need to know before starting work is material calculation. Given the terrain, the consumption of raw materials will be approximately equal to 15 tons per 100 square meters. m. You need to rent a skating rink weighing 10-14 tons from the supplier of asphalt crumb.
The preparatory measures that require the laying of asphalt chips are the elimination of shrubs and grass and the alignment of the relief of the road. If there is such an opportunity, it is better to cover the prepared, flat surface with bitumen mastic. So you fix the material and prevent crumbling of crumbs for the first time, until it is pressed under constant pressure of the wheels.
The technology of laying asphalt crumb with your own hands is not complicated: the work is carried out in 2 stages, pouring each layer of raw material and crushing it with a roller. One layer should be approximately 10 cm thick. After the final ramming, the road is ready for operation.
It is easy to work with asphalt crumb. Compared to other granular coatings, it wins because it becomes stronger and holds better over time, while sand and gravel are scattered along the curbs. In addition, the advantage of recyclables in its low cost. And although it is not as good in performance as the new asphalt, it is a real salvation for roads that have not been able to wait for funding for many years.
Thus, in the case of the construction of roads from asphalt crumb, a very dense and strong surface forms, which is rolled away in the future by the wheels of automobiles, becomes harder, does not collapse and does not erode.
