When the paving speed is decreased, less energy is available to push the material in the auger chamber. The screed has a tendency to ride up the head of material and more mix passes under the screed. User Tip: A common time for the operator to decrease the paving speed is when there is only one truck in front of the paverSuggested Best Practices for PAVER OPERATORS,Select a paving speed that balances delivery, paver capacity and the compaction process and pave with few if any extended stops. 2. Work with screed operator in establishing and maintaining the head of material within a plus or minus one inch tolerance. 3. Steer the paver holding to a pre-determined reference. 4.

With a consistent production and delivery flow, the speed of the paver will vary with lift thickness (thicker/slower; thinner/faster) and width of paver pass wider/slower; narrow/faster). Most equipment manufacturers will give a suggested maximum speed for their paver. A lot of agency specifications will specify a maximum speed, such as 30 or 40 feet per minute. MostAggregate Segregation - Pavement Interactive,The asphalt paver. Segregation occurs as a result of hopper operation, auger speed, and disruptions in paver movement. The chief detrimental effects of segregation on HMA performance are: reduced fatigue life, rutting, raveling, and moisture damage. These effects can cause a severe reduction in pavement life.9 Essential Asphalt Paving Tips That Improve Quality,,In an ideal paving operation, the paver will operate nonstop throughout the day, because a change in paving speed can directly affect the ability to lay a uniform mat. Speed changes also create challenges with timing the delivery of hot mix material in order to keep the hopper at least one-third full. Consequently, changes in paving speed are commonly caused by trucks inconsistently arriving at theLaser Technology - Stockpile Volumes,Laser Technology, Inc. is a Colorado-based manufacturer devoted to the design and manufacture of innovative laser-based speed and distance measurement instruments.

In fact, in most cases it causes segregation to be more likely to occur or to be worse. It is best to always maintain an adequate quantity of mix in the paver hopper, even between truckloads.
