Types and Classification of Railway Sleepers Advantages ANALYSIS AND DESIGN OF PRESTRESSED SLEEPERS

Pre tensioned concrete sleepers are usually preferred now days Reinforced Concrete and prestressed concrete sleepers are now replacing other types of sleepers except in some special circumstances like bridges etc where wooden sleepers are usedTYPE AND SPACING The sleepers shall be pre stressed concrete sleepers intended for track designs using centre to centre spacings of sleepers of 500 mm to 750 mm The sleepers are designed as fully prestressed sections where the limiting stresses are based on the fatigue resistance of the concrete

Prestressed concrete WikipediaProject Report on PRE STRESSED CONCRETE RAILWAY SLEEPERS

Pre tensioned concrete is a variant of prestressed concrete where the tendons are tensioned prior to the concrete being cast 25 The concrete bonds to the tendons as it cures following which the end anchoring of the tendons is released and the tendon tension forces are transferred to the concrete as compression by static frictionAbout 15 million prestrressed concrete sleepers are produced per annum by the various railways of the world out of which pretensioned sleepers alone account for over 70 INTRODUCTION CLASSIFICATIONS OF SLEEPERS
