What is the minimum size for a plate tamper used on pavers 3-1/8" and thicker?

1. 2,000 lbs

2. 3,000 lbs

3. 4,000 lbs

4. 5,000 lbs

The correct answer is: 4,000 lbs

The correct answer is based on guidelines established for the appropriate equipment needed for installing pavers of varying thicknesses. A plate tamper is essential for achieving adequate compaction when laying pavers, particularly those that are 3-1/8 inches thick and more. This size ensures the pavers are properly set to prevent future shifting or settling, which could compromise the stability and aesthetic of the installation. For pavers of this thickness, using a plate tamper with a minimum weight of 4,000 lbs is important because heavier equipment will provide the necessary force and efficiency for compaction. A lighter tamper may not generate enough downward pressure, leading to insufficient compaction and potentially causing issues such as uneven surfaces or premature wear. It’s also crucial to consider that different sizes of pavers require different weights of tampers for optimal performance; hence, the chosen weight reflects industry standards that ensure the longevity and functional integrity of the laid pavers.
