This is the only hand portable gauge available to provide the
required simplicity, quickness and precision to directly measure and
monitor the in-place engineering properties and do so at construction
speed. The device applies a constant load vibrating force to the
soil’s surface and measures the resulting displacement.
This dynamic technology simulates actual in-use conditions.
One instrument to link design specifications with compaction in 75
seconds for enhanced QC/QA.
Applications include subgrade, subbase, base monitoring the
strength gain of lime, cement, fly-ash and polymer stabilised materials,
monitoring the re-compacting of asphalt and cold in-place
recycling to peak properties to prevent wasted effort and damaging
over-compaction. The device compliments and provides alternative
to resilient modulus, Falling Weight Deflectometer, field California
Bearing Ratio, plate load test, dynamic cone penetrometer and
other measures of strength, stiffness, modulus and deflection.
