Alfred Neuberger and his team set benchmarks with almost every new project. The company, which has 22 employees specialises in a variety of fields including demolition, recycling, landfill and earthworks, has a considerable fleet of construction machinery.
Since the 1960s, the family has owned a large gravel pit in Ehrwald in the Austrian Tyrol, close to the Zugspitze mountain on the border with Germany. For recycling construction waste and RAP (reclaimed asphalt pavement), the company has a landfill site with a volume of 400,000 cu m (14.1 million cu ft).
“Since 2012 we have used a Rockster scalping screen RSS49, mainly in our gravel pit,” said the owner of the company that shares his name.
“Until this summer we regularly rented crushing plants from Haberl Construction Machinery, but we decided to buy our own R900 impact crusher. With the crushing plant they mainly recycle demolition waste, concrete, asphalt, as well as natural stone such as limestone.
“We had been renting Rockster crushers for years so we are convinced of the performance of the R900 impactor. The new Volvo engine with emissions standard is running even more smoothly and the fuel consumption decreased by about 15% compared to the older machine. The consumption per ton is really impressive.”
The main field of operation for the mobile Rockster crusher is recycling demolition waste and concrete to 0-63 mm (0-0.4 inches) for material base in road construction or backfills in building construction, as well as recycling of RAP or natural stone processing.
In one project, to rebuild a tunnel portal in the town of Lermoos, the road top layer was milled off and resurfaced. The Neuberger team recycled the old asphalt and crushed it to valuable grain with 0-16 mm in A + quality for road construction.
