Description

35-T0120/A
Lightweight deflectometer used to determine the bearing capacity and compaction quality of soils and non-cohesive subbases. Printer & PC-Software

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
