Check Thickness & Elevation

Compacting by Vibro Roller

Check Thickness & Elevation

• Location of Works : Public Road Heightening Works (Plan attached).• Location of Material : Crusher Plant at Desa Paku which distance 7 KM from Project Area• If the existing ground is bad / soften, base A/ base B for sub grade will be executed thickly 30 cm (compacted).• Installation of Peil schaal at left and right side for monitoring thickness of base A/ base B before and after compaction.

METHOD OF TRIAL COMPACTION (BASE A & BASE B)

• Dump Truck 12 m3 : 3 unit• Grader cater pillar : 1 unit• Vibro Roller Dyna pack 12 ton : 1 unit• Laboratory Apparatus : 1 Set• Survey Apparatus : 1 Set
