If the road surface is no longer even – one of the most important characteristics of a good racetrack – it has to be repaired.
The rehabilitation of these sophisticated circuits often needs to be completed in record time to ensure that the racetracks are ready for the start of the new season.
If, for example, bumps form on the start and finish straights of a motorcycle racetrack during the course of racing, it can have disastrous consequences. When braking ahead of a curve, the motorcycles begin to “sway” and can no longer be controlled. This poses too much of a safety risk to drivers, which means that the road surface’s profile and grip must be restored – a classic application for fine milling.
Occasionally, the slope must also be modified along defined sections of the track. This requires milling the surface layer and, if necessary, the binder course. Pavers and rollers are then responsible for paving and compacting the new asphalt surface. Sometimes it may even be necessary to produce a new base layer to restore the safety of the track for race cars or motorcycles. In this case, cold in-place recycling is often the fastest and most cost-effective method.
