Behavior of adjacent precast prestressed concrete box

Precast prestressed concrete adjacent box girders are widely used in short and medium span bridges. Rapid construction and economy are the main attractions of this system. The continuous flat soffit and relatively high span-to-depth ratio make this system aesthetically pleasing. However, reflective cracking and leakage have been reported along the longitudinal joints between adjacent boxes in

The performance of highways in Indonesia until today is yet to be optimum. Flexible or rigid pavement construction generally do not reach designed service lives, either due to the fact that the construction do not meet specifications or unavoidable excessive load. Precast and prestressed concrete system has been applied since 2007, but unfortunately the application has not been optimum due to

Post-Tensioned Concrete Slab Pros & Cons | eHow

Post-tensioned concrete slabs allow the structure to fully utilize the tensile strength of the steel reinforcing and the compressive strength of the concrete slab. However, the sheaths for the steel tendons must be carefully placed to provide the proper camber to the concrete slab; this requires more time to erect the structure than prestressed

Advantages & Disadvantages of Prestressed Concrete

Disadvantages of Prestressed Concrete. The following are among the advantages of using prestressed concrete. The unit cost of high strength materials being used is higher. Extra initial cost is incurred due to use of prestressing equipment and its installation. Extra labour cost for prestressing is also there.

Nov 25,  · Post-tensioned concrete is used for cast-in-place concrete and for bridges, large girders, floor slabs, shells, roofs, and pavements. Principles of Prestressed Concrete In concrete, a large prestressing force is applied by tendons embedded into it to develop high bearing stresses at the ends by the anchoring devices.

There are no standards or recommended procedures for the design of prestressed concrete pavements; thus design of this type of pavement presents unique opportunities and challenges. It also presents a great opportunity to use fundamentally based engineering design methodology rather than the relatively common empirical methods. It is to be anticipated that, as lifecycle costs assume greater

Advantages of Precast Concrete in Constructing Highways

As proved by the testing project of the Texas Department of Transportation in 2002 [4] and suggested by El-Reedy [5], post-tensioned panels provide the same design life as thicker conventional concrete pavements, using thinner slabs, which means that a 200mm post-tensioned pavement would have the same life as that of a 355mm conventional pavement.
