Videos for Dynamic CBR Measurement – in situ and portable lab

I highly recommend the use of the Light Weight Deflectometer for performance measurement of stabilisation outcomes. Every home should have one (only joking), but seriously, every civil construction team should consider the benefits of in-situ testing. The advantage of immediate and exceptionally reliable feedback coupled with the ability to adjust stabilisation operations in real time is very compelling.

The ZFG 3000 is an excellent tool and should be included in any professional contractors equipment list of assets. This tool should have a similar impact on the construction industry as the laser level. The ability to accurately and reliably measure this aspect of ground condition will improve the quality of the work and remove doubt as to the progress of the project.

I bought my ZFG 3000 and on the same day less than two hours later, it had paid for itself. Using this instrument, I was able to demonstrate scientifically, repeatably and independently the quality of the work that we had completed for our client. Ending the disagreement and creating an improved working relationship. Most jobs are not as confrontational as this was however, most jobs are built to a standard. The contractor can now measure as required, to know on site, at the time of testing if this standard is being achieved.

I strongly recommend the ZFG 3000 Deflectometer to any earthmoving, civil construction contractor. Good luck with your projects.

FH is now routinely using the LWD with very good feedback and useful engineering data. The equipment is an easy to use Zorn LWD.

The Light Weight Deflectometer (LWD) was first used in 1998 by the Minnesota Department of Transportation (Mn/DOT) at the Minnesota Road Research Project. Starting in 2005 the LWD has been used by Mn/DOT as an acceptance tool for the compaction of roadbed and miscellaneous embankment and trench construction, culvert treatments and other tapered construction.

Since hiring the LWD I have used it on numerous jobs in a wide variety of material types all over WA. The ability to give “real time” test results have worked particularly well for me as i can show my clients numerical values which gives them a direct understanding of some of the benefits using Betta Roads has brought to their road construction projects. The feedback I have been receiving over the last few months has lead me to purchase the LWD and incorporate its use as an integral part of our projects.
