Pavers with aspect ratios over what should not be used for streets parking lots?

• A. 4:1
• B. 3:1
• C. 5:1
• D. 2:1

Answer: (A)

In pavement design, aspect ratio is the length of a paver divided by its width. For heavy-load areas like streets and parking lots, keeping this ratio modest helps the paver distribute loads effectively and stay interlocked under traffic. When the paver is too long relative to its width, it behaves more like a beam spanning the base, concentrating stresses at the edges and joints. This increases the chance of edge cracking, joint distress, and movement under repeated wheel loads, reducing durability and surface stability. Therefore, pavers should not exceed a 4:1 aspect ratio for streets and parking lots. Shorter, squarer shapes (up to 4:1) provide better load transfer, interlock, and resistance to deformation.
