Abstract
Recently the sidewalk space is regard as comfortable area for city life, and it is required to establish the test method for the evaluation of safety and amenity. For keeping the safety of walk, the slip of pavement materials is the important factor There were some machines for measurement of slip-resistance, but they were not enough for the evaluation of sidewalk pavement.
In this paper, the development of new machine for sidewalk pavement materials which was based on the DF-Tester, and the evaluation test results were reported. The new machine was able to measure the coefficient of static and dynamic friction of side walk pavement. From these two parameters, it is able to evaluate the slip-resistance and the surface texture of pavement. From the test results, the coefficient of friction was not affected by the surface temperature of the pavement materials.
Finally, it was found that the value of coefficient of static friction for keeping the safety of sidewalk pavement is greater than 0.5.
