Abstract:

Considering that one of the crucial duties of microsurfacing is skid correction therefore there is some important factors to achieve this purpose such aggregate type, its specifications and gradation. Also type of adhesive materials and its amount can effects on microsurfacing skid resistance. This study presents a laboratory investigation of aggregate type and adhesive materials and their relationship to microsurfacing pavement skid resistance. The method of this study is developed for the evaluation of microsurfacing pavement resistance against skid. This method relies on ASTM E 303, using the British Pendulum Test. The test results report in British Pendulum Number (BPN). The verification of this method was achieved through measuring the skid resistance of specimens constructed in laboratory using two different aggregate sources and two adhesive materials. The results show that the river aggregates are more resistant than mountain aggregates against skid. Also, the results of resin specimens are more desirable than the bitumen specimens. The skid resistance was found to be related not only to aggregate type, but also to the type and percent of adhesive materials within an aggregate sample.
