Videos like this may seem simple but I find them beneficial professionally. In the field, information is usually hard to come by.

@@aidenmeehan9319 well that totally depends. I majored in structural engineering so I practiced that after graduating. I know that some interns stayed with the path and got office jobs as engineers with the testing company managing the test results from all the interns’ work. Others went down the geotechnical route. I also inspected rebar and concrete so I had more of a structural tilt. Nowadays I’m a financial advisor though made a career 180 after 4 years as an engineer. I’d sit down with a senior engineer at your company you’re interning for and ask questions on different career paths!

At first we have to take standard count. Our gauge has callibration so while when we took standard count may be some error ...density and moisture they will +/-2 erros its accpetable ...more than this not acceptable ....after this we will know the gauge is ok...then after we will conduct the test as same your procedure

Nice test but what does it mean back at the lab? What is a good reading or bad reading. From my understand as an retired superintendent, the fill test should match the existing soil compaction or you will have unequal settlement. All the test are a pain in the ass for the superintendent. We have to call for all test and inspections, and show them where and so on. Its an endless task among all the other daily jobs.

The material has to be collaborated in the lab prior to testing. The engineer will come and take about 60kg worth as a sample and conduct an Optimal Moisture Content test at the lab. This will generate a Maximum Dry Density figure as well as an optimum moisture percentage. On site with the NDM, you compare the results to these collaborated figures and overall are given another percentage based on the similarity of the results. A 100% reading would be an identical MDD with moisture reading under the optimum. Most councils across the UK require material to pass at 95%. A high moisture reading (from rain, for example) would affect the result as would a poorly compacted material

What is the initial PR value? what does it mean and how do I know what to use?
@kiritimatiswan19862 жыл бұрын
PR is the number you get from the lab. They provide you a proctor and an optimal moisture to shoot for.
@snarp4088 ай бұрын
PR is "proctor value" it is the dry density maximum of the materials you're testing. You take a sample beforehand, the lab will process it and find the max dry density. That is your PR number and it specific to the materials you're testing

工程师您好,有个关于TROXLER3440操作的问题请教一下。在操作过程中,将探杆由安全位置往下放入探孔中,界面不显示深度值,按START/ENTER键以后,显示Invalid depth ! change rod depth . Press START when ready .。应该如何操作才能正常显示深度值和仪器能正常检测。谢谢。
@doxscund88216 ай бұрын
My gauge has that problem too. I believe the Troxlers can switch modes, there should be a mode button and switch it to 'manual'. When you place the rod in the probe hole it should now ask you for the depth and you can input it manually.
