PRIMA 100 for Construction QA
PRIMA100 LWD for construction quality control, unbound layers, bound thin layersPRIMA100 Light Weight Deflectometer is portable and easy to use and provides first-class measurements of bearing capacity of natural soil and foundation layers. Like the traditional Falling Weight Deflectometers it applies an integrated high precision load cell for measurement of impact load of each individual measurement providing a correct bearing capacity result irrespective of soil type and material.
Equipment from Sweco is top-quality, durable, strong, reliable, stable and fast working. It complies with international standards, ASTM 2583, and is ISO 9001, 14001, OHSAS and AASHTO R-32 certified.
Use PRIMA100 LWD for control of:
- Natural soil and earthwork materials
- Compaction degree of the excavated and reused often mixed materials.
- Bearing capacity is as important as compaction. The stiffness of foundation layers is crucial in order to avoid cracking.
- Surface bearing capacity. You may discover that the existing materials are better than expected allowing you to potentially reduce the volume of more expensive material.
- Bearing capacity is essential in connection with rail construction when constructing foundation layers for track beds.
