I have studied about the expansion and contraction joints. In the rigid pavements, like the cement concrete pavements, the cement slab is laid on the sub-grade. The concrete changes its volume with the change in the temperature. Chapter 4 REPAIR AND MAINTENANCE OF RIGID PAVENMENTS 4.1 PRELUDE Regardless of quality of pavement material and design, increase in the vehicular traffic and changing environmental conditions will reduce the service life of pavement which ultimately results in its failure.

Pavement Manual Joints. We know that rigid pavement is constructed using reinforced cement concrete. One of the main factors affecting the destruction of concrete is shrinkage and cracks. To limit this, we know that we will provide some joints in buildings construction and others. The above same scenario is also applicable while we construct rigid pavements., JOINTS IN CC PAVEMENTS Joints are the discontinuities in the concrete pavement slab, and help to release stresses due to temperature variation, subgrade moisture variation, shrinkage of concrete etc. There are various types of joints in concrete pavement, e.g. contraction joint, construction joint, expansion joint and warping joint.
