PRIMA 100 Light Weight Deflectometer
PRIMA100 Light Weight Deflectometer (LWD) utilises an integrated high precision load cell for the measurement of the impact load of each individual measurement providing a correct bearing capacity result irrespective of soil type and earthwork material. PRIMA100 can measure on anything from clay to base gravel and crushed concrete. Knowing the bearing capacity of the soil and foundation materials ensures that the required performance is achieved. Bearing capacity is an important parameter when it comes to measuring construction foundation layer for roads and other areas. A correct road pavement compaction prevents lasting settlements and defects. Bearing capacity is as important as compaction. The stiffness of foundation layers is crucial in order to avoid cracking. Thus bearing capacity measurements are performed on old foundation layers immediately after the asphalt layer has been removed. The task is then to obtain the same bearing capacity with the new structure - or as close to as possible. In this way the new and the old asphalt will work uniformly and cracks can be minimised.
