Skid resistant road surfacingOmnigrip HF is a high-friction surface treatment (HFST) which is a veneer overlay applied to asphalt and / or concrete roads and highways to improve surface friction, resulting in decreased braking distances and threshold impact speeds in emergency situations. Comprised of a thermosetting modified compound which exhibits plastoelastic properties the OMNIGRIP HF system is engineered to hold high PSV aggregate permanently in position so that it doesn’t become embedded or displaced under the heaviest of braking, ensuring consistently high skid resistance and reduced braking distances over the design life of the system. Upon curing the OMNIGRIP HF system is resistant to all road contamination, including oil, petrol and de-icing salts with excellent adhesion to asphalt and concrete surfaces.

How does OMNIGRIP HF work?The concept of differing braking distances in respect to higher surface friction is developed from the formula d = V2 / (254* Au) which is used by many agencies around the world. The outcome identifies that vehicles braking on a surface with a higher level of friction after the brakes had been applied will come to stop in a much shorter distance relevant to the speed of the vehicle.
What results can reasonably be expected by using OMNIGRIP HF?Contrary to misconceptions within the traffic engineering environment, the installation of high-friction surface treatment does not necessarily equate to lower incident rates. It should be understood that the basic function of an HFST is to impart and maintain a level of friction and texture that is not achievable by traditional pavement construction methods.An HFST under normal traffic conditions has no impact on day-to-day driver behaviour and attitudes. Hence, an HFST is not to provide a reduction in traffic accident statistics that are directly attributed to behavioural consideration in its many and various forms.
In fact a HFST becomes an effective road safety instrument in emergency situations where conditions provide a driver with a situation having to brake suddenly to evade a potential incident. In these circumstances, the high friction surface of the road provides the physics and performance to allow a vehicle to obtain and maintain maximum friction contact with the road surface. This, in turn, allows the vehicle to decelerate more rapidly and for the vehicle to come to a complete stop in a shorter distance. Accordingly, in the event of impact, the threshold impact speed will be significantly lower than that of a vehicle attempting to stop on a pavement with a lower level of surface friction.In turn, this equates to a significant reduction in the likelihood of serious injury occurring due to lower speed on impact as the presence of a HFST is highly likely to affect the severity of damage and trauma inflicted. Meaning a fatality incident may be reduced to serious injury and/or an injury incident may translate to a property damage only outcome, all of which contributes to reduction of road trauma and the associated personal and financial costs associated with same.
