More than 500.000 measured kilometers
The first TSD was delivered to the Danish Road Directorate under the Ministry of Transport in 2004 and is still in regular use for bearing capacity measurements on state roads in Denmark.
Since then, the development has continued and the experience has grown as more than a dozen TSDs are in operation for various research projects and maintenance optimization tasks in USA, South Africa, Australia, China, England, Germany, Italy, Poland and Denmark.
