HIGH FRICTION SURFACING SCRIM® PERFORMANCE - MARK STEPHENSON (WDM®)
Mark Stephenson, Head of Consultancy Services at WDM®, gave delegates at the Road Surface Treatment Association seminar an insight into the research carried out on the effectiveness of high friction surfacing. WDM® have measured the in-service sideway force coefficient, or wet skidding resistance of HFS, across the UK and expanding to the US. The data collected supports the view that HFS provides the best long-term solution for achieving the necessary SCRIM® road survey machine values across the network particularly where a SCRIM® value above 0.5 is required i.e. on approaches to crossings, junctions and roundabouts.

TM2 US Trials
The WDM® texture meter, the TM2, took part in Network Level Macrotexture Measurement Equipment trials in the USA. The ‘rodeo’ style trials were held at Virginia Tech Transportation Institute in Blacksburg. The various machines were first tested against accurate material targets with different profiles and then over several routes on the Institute’s test road, with varying materials. The TM2 uses a transversely mounted laser to measure the road surface to calculate sensor measured texture depth (SMTD) and mean profile depth (MPD) and delivers raw data on a grid of 1mm x 1mm. Machines from Australia...

SCRIM® celebrates 50th anniversary
To celebrate the 50th anniversary of the SCRIM® road survey vehicle, we shared a SCRIM fact each week during 2017.
Fact #52: In 1990 WDM® was the first to have traffic management employed when SCRIM® measured surface friction of roads in Singapore. Police outriders stopped traffic at junctions to allow the survey to continue without interruption.
