Holes can be covered in asphalt using infrared

Maintenance crews asfato the streets and roads in Brazil seem to have a special talent: they always turn a hole in a spine. Now, engineers from a U.S. company developed a system that seems to be proof of such undesirable talents.

Maintenance of asphalt

Apart from the use of maintenance teams prepared, a repair of paved roads is today made ​​by a slow and expensive process: the asphalt is cut and fully withdrawn, into a larger diameter than the hole. Following the passage receives a new layer of asphalt. The process works well for highways, streets but is impractical because it requires the same apparatus machinery that a new paving.

This is precisely the asset of the new equipment, which is compact and can be used without major disruptions to traffic and a lower cost. The machine maintains the asfato using infrared rays.

Repairing asphalt with infrared

The technique of repairing asphalt operates with infrared fusing the asphalt, both the old asphalt around the hole, and the new asphalt which is placed only in sufficient quantity to fill the hole.

The fusion eliminates the interface that is created by traditional maintenance process, besides being responsible for the infiltration of water, turns into an area of ​​low strength, ready to generate a new hole.

Another advantage is the small team of maintenance required. Are typically used 4-5 workers. Using infrared equipment, maintenance can be performed by only 2 persons.
