How to measure in-situ modulus in confined spaces and get immediate repeatable results
One of the methods for measuring dynamic modulus on site and getting repeatable results immediately is using the Light Weight Deflectometer (LWD). By measuring the modulus value, the Light Weight Deflectometer (LWD) provides the direct link between the design specification (modulus value) and the actual site condition (modulus value).
Getting immediate repeatable results means that on-site decisions can be made straight away. The Light Weight Deflectometer can be used in confined spaces and difficult to access locations, like in trenches, with no support equipment required.
Site characterisation is unarguably the most important, but also most difficult, component of geo-engineering. The ZFG 3000 Light Weight Deflectometer (LWD) with GPS is used for compaction control on sub-grades by measuring the stiffness (modulus) directly in the field, according to ASTM E2835-11 (2015). This equipment is designed to improve the quality of site characterisation and reduce the difficulties involved.
Measuring the level of compaction or bearing capacity of the formation, sub-grade, sub-base and unbound layers and being able to get results immediately to make decisions is very important. The LWD enables you to do this in applications that include road and rail construction, airport runways, taxiways, aprons and parking areas, landfills sites, freight terminals, tank farms, wind farms, temporary pads for mobile crane outriggers or piling rigs, dams, embankments, building and temporary structure foundations, pipe & cable laying, electricity pylons and others.
Insitutek imports, sells and services, unique geotech equipment that has proved of great benefit to those who use it. It has a particularly beneficial role to play for those compacting soil in infrastructure projects.
I would hate to go back to doing the Plate Load Test using the old method using dial gauges. It would be so time consuming, not to mention manually recording and then processing all the results.
I have known the team at Insitutek for over ten years. Their professionalism, positivity and enthusiasm for their work is outstanding and I am pleased to recommend them.
