HEILIT+WOERNER Bau-GmbH has been established in 1970 from Tief- and Stahlbeton Gesellschaft m.b.H. as a wholly-owned subsidiary of HEILIT+WOERNER BAU AG.
In Austria, the employer can also benefit from the Quality of concrete pavement built by HW Tthe favorable service properties are:
- Road safety: skidding resistance, no deformation and no ruts, little noise development, ride comfort - even sur-face
- The durability and economic efficiency: almost maintenance-free -no traffic jams caused by repair work sites, long life
[1,2] A 2 South Expressway, Guntramsdorf
General resurfacing of the old express-way with removal of the existing sub-grade, both lanes over a length of approx. 8 km; major work: two-layer placing of the 25 cm thick concrete pavement (21 cm thick bottom concrete with recycled aggregate, 4 cm thick upper concrete with exposed concrete surface) on an asphalt base with a HW concrete paving train.
[3] A 1 West Expressway, Salzburg, concrete safety barrier
Optimum combination of road safety and quality/efficiency: Construction of a more than 25 km long concrete safety barrier using the slipforming method by HW specialists. Based on our experience, the concrete mix formula has been optimized so that it has a satisfactory stiffness when the formsare moved and a closed surface isobtained without cost- and labor-intensive rework.
 | [4] West Expressway, Seewalchen
General resurfacing of the Salzburg and Vienna lanes with removal of the existing subgrade (each lane about 10 km), using a two-layer concrete pavement (21 cm thick bottom concrete with recycled aggregate, 4 cm thick upper concrete with exposed concrete surface) on an asphalt base, and construction of a concrete safety barrier. HW special slipform pavers and skilled personnel were employed for this work. |
