Foto de stock - 12 September 2019, Bavaria, Greding: Laser beam signs are mounted on a truck to check the load capacity of roads. All state roads in Bavaria are measured for their bearing capacity. The pavement is evenly loaded with the truck weight of ten tons. A special laser measures how much the road surface deforms under the load at a driving speed of between 30 and 60 kilometers per hour in the gap between the twin truck tires.
