Diagonal post-tensioned pre-stressed jointless cement concrete pavement is a new form of road building. There are double diagonal prestressed steel strands in the cement concrete pavement which exert force on the prestress in the horizontal and vertical direction of the road, so that transverse joints are not needed in the slab.

Posttensioned Concrete - Portland Cement Association

Post-Tensioned Concrete. Designers use post-tensioning as a way to reinforce concrete by prestressing it. In prestressed members, compressive stresses are introduced into the concrete to reduce tensile stresses resulting from applied loads including the self weight of the member (dead load). Prestressing steel, such as strands, bars or wires ...

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.

These losses must be accounted for to ensure that the required prestress level is maintained over the length of the slab over the design life of the pavement. Losses of 30% to 50% of the applied prestress force can be expected for a well- constructed posttensioned concrete pavement. Several factors contribute to prestress losses: 1.
