The need to have the use of all kinds of road surfaces for car testing led to the construction of the experimental car track by the Adam Opel AG. This has been a full experience in this kind of work. The making of a purposely defective road surface has been more difficult than was supposed, and the fast track, provided with all kinds of modern devices, has been studied to its minutest details. Its transversal section (a cubic parabola), with strong camber, made it impossible to use normal machinery, which is only apt for plane surfaces. A type of sliding formwork on rails, suitable for continuous concreting, was adopted. The total length of the track is 32 km. It includes a concrete base and a variable surface, which incorporates all kinds of surfaces that may be met with, in any state of repair. The construction time was 235 days.
