Optional slip rate check

The measured frictionis very dependent the slip rate of the device measuring wheel. Each device operates with its own slip rate, which is different from the other devices. It is therefore necessary to distinguish these slip rate to tend towards a common pavement scale. It is in this context that an original device has been developed to measure this slip rate whatever the measuring device.
