Pre Stressed Concrete Sleepers Crushing

Update date: 12-19

Prestressed concrete railway sleepers. the bearing area of sleepers below the rail seat and over the ballast should be enough to resist the crushing due to rail seat and crushing of the ballast underneath the sleeper. vi. the sleeper design should be such as to facilitate easy removal and replacement of ballast.
