Light Weight deflectometer

Descroption

The dynamic plate load test performed with the Lightweight deflectometer is used to determine the soil bearing capacity and compaction quality of soils and non-cohesive subbases, as well as for soil improvement applications. Built-in soil layers can easily be tested without load abutment, facilitating quick assessments of test lots even under limited space conditions. The test method is suited to coarse-grain and mixed grain soils with a maximum grain size of 63mm and can be used to determine the dynamic modulus of deformation of soil in the range Evd = 15 to 70 MN/m².

Applications

• Road and railway construction, earth moving
• Quality assurance in canal construction
• Compaction monitoring in pipe trenches and cable ducts
• Testing of pavement bedding
• Testing of foundation backfill
• Quality inspection in boreholes
• Testing of modulus of deformation in line with soil exploration

Feature

• Fast and cost-saving: maximum 2 minutes per measuring point
• No vehicle required
• Immediate on-site evaluation of test results
• It can be easily operated and carried by one person only
• Testing can be achieved in difficult to reach locations
