To illustrate this point, imagine a breakdown roller with 67inch drums and a frequency of 3800 vpm performing a sevenpass pattern. With those details in mind, that roller can keep up with a paver laying a 12footwide mat at 35 feet per minute. However, when the mat thickness is less than 1 inch, the paver could be moving at 52 feet per minute.
