Can vertical loadings from the troughing be supported by the existing sub structure/formation without additional strengthening?
The pressure on the bottom of the trough with 25tonne axles loadings is less than 200MPa. With 10tonne axle loads it is between 50 and 100MPa. The section installed in Rotherham Bus station with 2500 buses per day was laid on asphaltic sand laid on top of a reclaimed rubbish tip. Heavy road vehicles do the most damage to tramway tracks, eg. the shared track in Moseley Street Manchester. The LR55 concrete trough distributes bus and HGV tyre loads into the sub base at a lower pressure, than when they act directly on the pavement surface. All the lab testing up to 80tonne axle loads was on dry conpacted sand.
