Structural Design of Interlocking Concrete Pavers for Municipal Streets and Roadways

Interlocking concrete pavers (ICP) have the ability to spread applied loads via the interlock between each unit. This means that the surface does not respond structurally as single pavers but as a composite paved surface. This structural characteristic of ICP allows the design method for these pavements to be based on flexible pavement design. In this course, we examine the ASCE and ICPI structural design methods for ICP and review examples using different soil strengths/stiffnesses and traffic uses. Finally, we survey the design and construction support material and software available from the Interlocking Concrete Pavement Institute.

Upon completion of this course, the Learner should be able to:

• Describe how interlocking concrete pavers act as a structural system and spread applied loads.
• Recall the origin of the ASCE National Standard: Structural Design of Interlocking Concrete Pavement for Municipal Streets and Roadways.
• Apply the AASHTO structural design method for flexible pavements to interlocking concrete pavements (ICP).
• Use the ICPI design software and Tech Specs to support the structural design of ICP roadways.
