Track surface properties:
Hardness:
Hardness or stiffness is a function of the type of binder used and the climatic conditions where it is used. ViscoRide tracks have been installed in varied
climates.
The success of our tracks is largely due to the high quality of the binder
that we use. Hardness or stiffness also results from the maintenance regime
employed. The state of a ViscoRide track could be altered and controlled by the way grooming is performed. It is therefore very possible to groom the track to a state of it being “dead” to “good” to “fast”. These conditions are then measured with a Cleg Hammer to and recorded to avoid future perception problems. It is also possible to prepare the track in such a manner that will restrict speeds to between 12 to 15 seconds per furlong.
The material over compacts when subjected to:
- Excessive vehicular traffic, such as ambulances running on the track during race
meetings
- Excessive grooming due to problems caused by heavy vehicle traffic on the
Surface
- Poor maintenance practices
Horizontal friction, rebound and shock absorption:
- The binder combined with the fibre and the sand affords good grip, rebound and
shock absorption.
- The photo below shows that there is no evidence of “shoving”, a condition which
may indicate slippage.
- There is also no evidence of material loss that may cause “projectiles” and
Possible injury.
- It is also very clear that hoof penetration is limited to the top 20mm of the
surface. In order to prevent hoof retention, it is important to control surface
penetration. ViscoRide does just that.
