However, either type can be effective. “All pavers, two- or four-track, are capable of meeting ride specs under the right conditions,” Devonshire concludes. “There are many determining factors for successful paving, but some of the most important are a sound, accurate foundation, a well-maintained stringline, appropriate equipment (plant and paver) and a well-trained crew.”

When bigger isn’t better

While size and weight can enhance smoothness, it isn’t always best to use the largest paver available. “Jobsite conditions, such as a stable track line that is capable of supporting a heavier mainline paver, clearance from the back of the pavement, cul-de-sacs or obstructions often make it more advantageous to use a smaller paver,” says Hite.

Logistics also factor into the equation. How much room do you have to maneuver a paver into the jobsite, asks Devonshire. Can you drive it off a trailer or do you need a crane to unload it? “If you’re using a full-size four-track mainline paver in a residential cul-de-sac, you may not have enough room to maneuver it,” he points out.

Also consider logistics outside of the unit itself, says Hite. “The biggest factors in paving are consistent supply or delivery of the concrete and consistency of the concrete mix,” he comments. “If a consistent, continuous supply of concrete cannot be maintained to keep the paver moving continuously, if access is limited, paving half width should be considered. An even, compacted surface for the crawler, an accurately set and undisturbed stringline, as well as a crew working in sync are also critical.” 

Get It Right From the Start

Many paving projects start with curbs and gutters. Because they set the grade for the entire job, getting them right is important.
