TM2
The TM2 mini texture meter from W.D.M. Limited is an innovative approach to measuring the road surface texture and in 2012 was an Innovation of the Year finalist. It is a faster and more reliable measure than the traditional volumetric ‘sand-patch test’ method for compliance testing of a newly laid surfacing.The TM2 ensures any new surface or reinstatement is delivering the correct texture depth by calculating and storing Sensor Measured Texture Depth (SMTD) and Mean Profile Depth (MPD)

Friction testing
Friction testing
WDM® began developing and manufacturing the first SCRIM® road survey Machine for the Transport and Road Research Laboratory in the 1970's to measure friction and identify lengths of roads with low skid resistance.
Since then Highways Agencies around the World have used WDM® SCRIM® vehicles. In the UK and New Zealand, where SCRIM® has been used with a skid policy, wet road accident rates have been reduced by nearly 40%!
