• Contact friction coefficients for glass to glass surfaces were measured using glass beads with various diameters (ranging from 0.6 mm to 5 mm). The tests were conducted on two different friction testing apparatus (pulling and sliding devices). All particles were tested under equivalent normal stress ranging from 34.5 kPa to 207 kPa on clear or smoked glass plate with environmental conditions ranging from dry to flooded with tap water or flooded with motor oil. The test results indicated that the coefficients of static and dynamic friction increased when flooded with water. Meanwhile, the static and dynamic coefficients for a surface flooded by motor oil were slightly smaller than the ones under dry surface condition. The average coefficient of static friction was found to be O.162 (or 9.2°friction angle) for the dry clear glass surface environment and 0.277 (or 15.5°friction angle) for the water flooded clear glass surface environment.
