Looking for a testing UK testing company that’s reliable, fast and great value? At Hixtra you'll speak to the right person straight away and will have your testing arranged in next to no time!
We are ready to carry out all your on-site and laboratory based testing for soils, concrete, aggregates and geotechnical samples. We specialise in rapid deployment for plate bearing testing, CBR testing and plate load testing.
There are no direct impacts at all. It's non-invasive testing as the video quite clearly shows. However, indirectly, the use of a vehicle to get to the site will of course emit emissions, similar to all other site activities. But this is 'scraping the barrel' to appease your question.
This channel is seriously underappreciated like these video from your channel really are informative compared to most of the videos i've ever watched. Thanks for the loud and clear instructions
Insitu and Lab CBRs will likely be quite different because of the constraining effect of the lab CBR mould, compactive effort and such like for coarser grained materials. Undisturbed fine grained samples for Lab CBR should yield similar results to Insitu CBR tests.
CBR (%)= 6.1 × 10^-8 × (k762)^1.733 where k762 is the Modulus of Subgrade Reaction, defined as the applied pressure under the loading platen divided by the displacement (normally 1.25mm) with a plate of 762mm (30 inch) diameter. The Modulus of Subgrade Reaction for other plate sizes can be determined using an appropriate conversion factor
there are many-weighing balance to measure the weight of the vehicle and its material together....but out point it to check the load from the loading gauge which is shown in the video and monitor at 5, 10,15, so on up to 100kN.
