• Description:
  Recently, much criticism has been directed toward the use of vibratory rollers to compact bituminous concrete. The results of the study reported here indicate that when these rollers are operated properly they can produce dense, strong, smooth riding pavements. It is important that, as with any equipment, the rollers be used properly. The authors offered the following suggestions regarding the use of vibratory rollers. 1. The roller operator should be thoroughly familiar with the roller. 2. The roller should be well-maintained. This is particularly true of the frequency and amplitude mechanisms. 3. When rolling, the following vibratory settings should be used: a. Frequency minimum 1,800 vpm; b. Amplitude low on surface courses (for smoothness), high on bituminous base courses; c. Speed maximum 3 mph; 4. The roller should not be allowed to vibrate when standing or reversing direction.
