Evaluation of Skid Resistance Performance Using British Pendulum and Grip Tester

A good road surface texture is very important to minimize road accident due to skidding problem. Many tools are used to measure skid resistance of road surface such as British Pendulum and Grip Tester. British Pendulum can be classified as traditional tool while Grip Tester is an advanced equipment. British Pendulum Number (BPN) and Grip Number (GN) are the output values from the respective tools. The main objective of this study was to establish relationship between BPN and GN. The tests were conducted on Asphaltic Concrete Wearing Course (ACW20) road surface located at selected Expressway in Selangor and State Road in Melaka. The results show a very weak correlation between both tests where the regression value was less than 0.19. It is recommended that further investigation and more tests on different types of surface be conducted to improve the correlation between the BPN and GN.
