SCRIM® Surveys
For more than half a century W.D.M. USA Limited have been carrying out continuous pavement friction measurement in other countries around the world to help reduce crashes and save lives – now they are ready to revolutionize the safety performance management of US roads.
WDM USA’s fleet of SCRIM® road survey machines is now delivering continuous friction measurement surveys across the US network, including around horizontal curves.
Studies in both the United Kingdom and in New Zealand show that introducing a wet road skidding policy, and working with the WDM SCRIM® machine, helps reduce crashes by between 30 and 40%, over and above the results of other safety improvement programs
Measuring, monitoring, and maintaining pavement friction – especially at locations where vehicles are frequently turning, slowing, and stopping – can prevent many road departures and intersection-related crashes, resulting in fewer serious injuries and fatalities.
The FHWA, who are promoting ongoing pilot studies that compare continuous pavement friction testing technologies to State DoT’s LWST equipment, say Continuous Pavement Friction Measurement best practices and proven technology present an exciting opportunity for the U.S. road safety community.
