Progress with Adhesion-Improving Bitumen Additives
building in Sweden was about 0.7 percent of the asphalt consumption in the U.S. (45,000 vs 6,000,000 tons in 1955). For this same period, the usage of additives in Sweden was approximately equal to the total usage of additives in the U. S. The aggregate has a greater affinity for wager than for bitumen, therefore, a wet

As the mill rotates, the ball moves with the mill wall without sliding back. Because of the circular motion, a radial force FR acts on the ball, always outward, as illustrated in the figure. The magnitude of FR is: mV2 m(2,RMN/60)2 FR- RM RM (8) where m is the mass of the ball, Rm is the mill radius, and N is the mill speed in rpm.
