SCRIM
SCRIM (Sideway-force Coefficient Routine Investigation Machine) is a machine, originally developed by TRL Limited in the United Kingdom, in order to measure the wet skidding resistance of a road surface.
SCRIM has a daily survey capacity of 200 to 300 km depending upon road type. A SCRIM survey in the UK can be undertaken at two different target test speeds of 50 and 80 km/h. The permitted speed range covering these target speeds is 25 to 85 km/h. Skidding resistance data recorded at speeds within this range can be speed corrected to give equivalent values at 50 km/h.
