It's common to use Gaussian white noise as a simple method of creating a random road profile - take a look at the link below for more information:

https://www.researchgate.net/publication/305843639_Numerical_generation_of_road_profile_through_spectral_description_for_simulation_of_vehicle_suspension

To further add to my previous answer, if you are aiming for a particular class of road (e.g. Class C from ISO8608) you can calculate the Power Spectral Density of the white noise input, and then scale the amplitude up/down to match the PSD from the real road.

At a vague guess I would start with white noise with an input amplitude of 30mm, and work from there.
