Articulated Steering All Wheel Drive Combination Bucket CASE MW24C
Compaction The process of mechanically densifying a soil, normally by the application of a moving or dynamic load.
Factors of Compaction Equipment Selection Page 42 Student Handout • Type and properties of the soil • Desired density • Desired lift thickness • Size of the job • Stage of construction (subgrade, subbase, or base course) • Compaction equipment available
Ranges of Soil Types ForSoil Compaction Equipment. ROCK SAND 100% SAND/CLAY 50% CLAY 100% SHEEPSFOOT PNEUMATIC VIBRATORY SMOOTH DRUM PADDED DRUM HIGH SPEED TAMPING FOOT
TEST STRIPS • 40’ to 100’ feet long • Lift thickness of 6 ” to 8” • 3 passes by each type of compactor Additional test strips determine: lift thickness required passes by compactor optimum compactor speed resonant frequency (vibratory compactor)
Compaction Equipment Selection • Static Weight = Sheepsfoot Roller
Compaction Equipment Selection • Kneading Action = 13 Wheel Towed Pneumatic Tire Roller
Compaction Equipment Selection • Impact (or Sharp Blow) = High Speed Tamping Foot Roller
Compaction Equipment Selection • Vibration (or Shaking) = Vibratory Roller
•Test every lift as soon as compaction is completed. • Test every roller lane. • Test obvious weak spots. • Test roads and airfields every 250 linear feet, staggering tests about the centerline. • Test parking lots and storage areas every 250 square yards. • Test trenches every 50 linear feet. • Remove all oversized materials. • Remove any pockets of organic or unsuitable soil material. • If initial checks are satisfactory, increase the distance between tests as construction progresses.
