Monitoring the skid resistance of a pavement's surface is essential from a safety and maintenance perspective. The GripTester is a surface friction tester which is used world-wide to accurately measure skidding resistance. It can be towed at normal traffic speeds or pushed at walking pace. The survey data is collected and stored in a computer. GripTester results are immediately available in a concise and useable format.
GripTester for Roads
The GripTester skid resistance survey is used to:
Identify areas of poor surface friction.
Make informed decisions for maintenance priorities.
Test road and pedestrian area accident sites.
Test horizontal road markings.
There is a well established relationship between GripTester and SCRIM results: GripTester results can be used to derive a SCRIM value.
GripTester and Local Authorities
The GripTester is of particular use to local authorities for the following:
Identifying areas of poor skidding resistance.
Measuring friction characteristics at road and pedestrian accident locations.
Assessing the friction-characteristics of road markings.
Testing for restoration of skid resistance.
Measuring skid resistance after surface restoration.
Assessing surface friction after road reconstruction.
