Improving safety on the ground.
With this order from August 2016, ÖBA made the airfield at Vienna Schwechat Airport a lot safer: to minimise the risk of jets hydroplaning during take-off and landing, grooves were cut into the asphalt at right angles to the direction of travel.
This technique, referred to by specialists as “grooving”, ensures that surface water drains more quickly. A special device called a “bumpcutter” was used. The ÖBA team worked in night shifts, and their high level of precision and coordination allowed this fascinating project to be brought to a rapid and successful close.

Working around the runway lights is not a problem for ÖBA either – they just use smaller joint cutters.© PORR
The end result fully satisfies all of the employer’s high requirements.© PORR
