Load transfer at construction joints can be provided by smooth dowels or other load transfer devices.

• A. True
• B. False
• C. Not Applicable
• D. Only Dowels

Answer: (A)

Load transfer across construction joints is needed so the two concrete pours act together under load. A smooth dowel is a common way to pass shear across the joint without fully bonding the pavement or slab, allowing movement from shrinkage, temperature changes, or restraint. But dowels aren’t the only method—other load transfer devices such as keyed or grouted connections, aggregate interlock, or grout-filled dowel assemblies can also transfer the load. Because there are multiple valid ways to achieve transfer, the statement is true.
