Transport route engineering
The path is our goal.
PORR is the experienced specialist for the complete realisation of transport routes such as motorways, federal, rural and district roads, airfields and logistics areas as well as outdoor facilities. The portfolio is supplemented by petrol station construction with WHG areas, pipeline construction and landfill construction.
Our core competences include the economical and safe construction of all types of traffic surfaces using the following construction methods:
- Rolled asphalt (in conventional and compact construction)
- mastic asphalt
- Concrete pavements
- Paved surfaces
With associated companies for asphalt production and building material recycling, we continuously guarantee optimum building material properties and thus ensure independence and economic efficiency in construction. Monitoring by our own building materials laboratories ensures the high quality standards.
Our highly trained employees, together with experienced managers, meet the individual requirements of our public and private clients.
Contact persons.
Building is a people business. This makes personal contact all the more important. Here you will find your contact persons for transport infrastructure construction in Germany.

Roads and transport routes.Your competent partner for innovative solutions

In modern road construction, engineers and construction companies are faced with the challenge of designing road surfaces that meet the highest standards of durability, driving comfort and environmental compatibility. Material composition, processing techniques and specific requirements play a decisive role in the choice of paving method, with innovative construction methods contributing to efficiency and sustainability in road construction. Two construction methods that characterise road construction are based on roller and mastic asphalt and offer the benefits of rapid use after paving.
In addition to the construction methods, recyclability also plays a decisive role. The careful use of valuable resources is of great importance in transport route engineering. Materials such as asphalt, concrete and soil are not simply disposed of, but carefully processed and recycled so that they are available again as high-quality building materials. According to the German Construction Industry Association, more than 90 per cent of the road surface excavated each year is recycled. This recycling rate has clearly exceeded the requirements of the EU Waste Framework Directive for years.
