Light Weight Deflectometer
Description & Specification
Light Weight Deflectometer
Categories:
Road Testing Equipment
Technical Specifications
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. 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.
Applications:
Compaction monitoring in pipe trenches and cable ducts
Testing of pavement bedding
Testing of foundation backfill
Road and railway construction, earth moving
Testing of modulus of deformation in line with soil exploration
Quality assurance in canal construction
Quality inspection in boreholes.
Main Features:
Immediate on-site evaluation of test results
Fast and cost-saving: maximum 2 minutes per measuring point
It can be easily operated and carried by one person only
Testing can be achieved in difficult to reach locations
No vehicle required.
