CONSTRUCTION JOINT

a joint between

slabs that results

when concrete

placed at

different times -

can be further

broken down

into transverse

and longitudinal

construction

joints -

Longitudinal construction

joints also allow slab

warping without

appreciable separation or

cracking of the slabs. -

Workers manually insert dowel bars into the construction joint at the end of the work day.

Construction joints

should be planned so

they coincide with

contraction joint

spacing to eliminate

extra joints.
