Lateral Resistance Test

 

SECTION 9: Lateral Resistance Test

 

Test Procedure:

1. The test arrangement consists of a suitable of rail fastened to the rail seat of one sleeper with the rail fasteners. The loading head is to be fixed against translation and rotation. The wood block shall be thick 254 mm x 254 mm x 19 mm 5 ply, exterior grade plywood.
2. A preload of 90 kN shall be applied to the gauge face corner of the rail at the angle of 30 degree from vertical axis. Release the load and set zero to the dial gauge.
3. Load will then be applied at the rate of not more than 22 kN per minute until a total load of 155 kN has been applied.

 

Acceptance Criteria:

If the rail base moved laterally not more than 3 mm under the load of 155 kN, the assembly would be considered satisfactory.
