Joint, repair and surface technology

Concrete or asphalt? We ensure a perfect result.

A dedicated department of ÖBA deals with joint, repair and surface technology (JRS). Each year, the department seals joints in road construction which if strung together would result in a stretch of approximately 1,000,000 m, and they replace 10,000 m² of concrete flooring with rapid hardening concrete.

Surface protection layers with EP grip.

In order to increase the grip of a road, we apply a protective layer of epoxy resin (EP) and a special chippings interspersion on its surface. The colour of the special chippings provides for lighter roadways and therefore greater safety in two respects, especially in tunnels. 

Joints in asphalt and concrete.

Properly executed joints and high-quality filling material significantly extend the service life of roads and thus contribute to maintaining the value of the infrastructure.

Joints sealed with hot sealing compound, cold sealing compound and joint profiles.

For asphalt and concrete surfaces, a joint seal with the correct filling material prevents frost damage and corrosion in concrete surfaces. 


In grinding, irregularities are ground out of surfaces or structures are cut into the surface. The process improves the grip of the road surface and at the same time also reduces the noise development.  


Grooves are cut in the road surface so that surface water will quickly run off from the roadway. Aligned in the direction of travel, they reduce noise development. 

Guiding system for the blind.

On existing surfaces, milled guiding systems for the blind ensure accessibility at railways, on pavements or at other busy pedestrian areas.

Renovation of joints.

When the flexible filling material of the joints develops leaks resulting from weather conditions, it must be carefully removed and renewed. 

Renovation of cracks in concrete and asphalt surfaces.

Cracks in concrete and asphalt do not necessarily mean that a road must be rebuilt completely. Often, it can be restructured selectively. This avoids unnecessary costs. For this purpose, the cracks are first cut open cleanly and sealed with joint sealing material; broken concrete slabs are also anchored and dowelled. 

Renovation of concrete slabs.

Concrete failure is often visible in the form of damage to the edges of concrete slabs. With the use of quick-setting renovation mortar, damaged slabs can be repaired quickly and efficiently. 

Renovation of asphalt pits.

During the renovation of asphalt pits, the damaged surface is prised open, cut out and filled with special renovation asphalt. 

Rapid hardening concrete in road construction.

Not only asphalt, but also concrete can be quickly processed in road construction. ÖBA uses rapid hardening concrete with curing times ranging from two to six hours, ensuring that concrete surfaces of up to 300 m2 are paved in a single night shift.

Supporting ribs.

The areas of a road where asphalt changes over to concrete slabs, as well as roadway transition structures or expansion joints, are exposed to particular stress. We strengthen these weak areas in the asphalt by using supporting ribs made of a special mortar. 

In-pavement lights.

In-pavement lights or surface lights can be found on runways as well as on taxiways and apron areas of airfields. They are installed virtually at ground-level and are an important guidance aid for pilots when manoeuvring on the ground.
