The bottom line
Asphalt surfaces can be rehabilitated using different methods depending on how heavily the surface and/or sub-base is damaged. Concrete surfaces can be re-profiled with cold milling machines or alternatively removed with excavators and then newly paved. When expanding an existing airport, the construction of additional air operations areas must meet the requirements applicable to new airport construction.
WIRTGEN GROUP technologies have been used to build, extend, and rehabilitate many runways, taxiways, and aprons for stationary air traffic around the world – using technologies from BENNINGHOVEN, VÖGELE, and HAMM for asphalt and technologies from WIRTGEN for concrete.
