concrete movement joint

Joints

A construction joint (see Figure 6) is a joint between slabs that results when concrete is placed at different tim This type of joint can be further broken down into transverse and longitudinal construction joints (see Figure 7) Longitudinal construction joints also allow slab warping without appreciable separation or cracking of the slabs.

Where do I need to use isolation or expansion joints in

Contraction or control joints also absorb some movement; however, their main function is to control the location and geometry of the natural cracking pattern in the concrete slab Because pavement performance can be significantly affected by the planned use and location of isolation and expansion joints, care should be taken in their design.
