Proper layout and construction of joints is critical for concrete pavements to perform as the designer and users want and intend.
A number of publications and guidelines are available to help both engineers and contractors properly design and build joints in concrete pavements.
This page provides joint layout resources for engineers, designers, and contractors working on concrete pavements. Joints are planned to help control where cracking occurs as concrete shrinks and moves with temperature changes, so their spacing and placement directly affect long-term performance. The attachments below include guidance on joint layout for roundabouts and intersections.
