Hypac C784 tandem vibratory rollerOffering an 84-inch drum width, the C784 tandem-drum vibratory roller has high vibration frequencies and increased centrifugal force, which makes it ideal for Superpave projects. With operating frequencies of 4,000 and 3,400 vpm, it can achieve working speeds up to 4.5 mph while maintaining 10 impacts per foot. It generates 34,655 and 41,235 pounds of centrifugal force in low- and high-amplitude, respectively.
