Variable Slip Skid Resistance Testing for Road Safety Investigation and Pavement Management
The relationship between surface friction and roadway safety has long been recognized by transportation agencies and concern with the number of accidents occurring in wet pavement conditions has grown. For this reason it is imperative for road safety and road asset management divisions to undertake pavement wet skid resistance survey on a routine and regular basis. Many kinds of equipment are available to measure skid resistance on road surface, such as side force tester, Lock Wheel Tester, Fix-Skip Tester and Variable Slip Tester. In this paper, Norsemeter ROAR MkII, a new kind of variable slip tester, is introduced. Norsemeter ROAR MkII can be operated on both fix slip mode and variable slip mode. It will be demonstrated in this paper that the testing results from Norsemeter ROAR MkII are useful for both road network condition monitoring and safety investigation of black spot area through stopping distance analysis and lose-of-controlled analysis. Therefore, it is believed that the application of Norsemeter ROAR MkII variable slip skid resistance testing can help various road controlling authorities to make better decision on road maintenance programs and road safety improvement programs.
