Types of rigid Pre-Stress Concrete (PSCP)

• PSC also known as Post Tensioned Concrete Pavement. Normally place in specialized
locations such as airports. The concept for precast pavement incorporates prestressing.
Prestressing not only improves the durability of the pavement, but also permits a
significant reduction in slab thickness by inducing a precompressive stress in the
pavement that must be overcome before tensile stresses that lead to cracking can
occur.

• Mostly done in factory
• Easy installation
• Save cost

Tension
Tensioned Cable
Applies a compressive force on the bottom of the
concrete. This neutralizes the tension force on
the bottom and the concrete does not bend
