(OP)
I was told I needed a Screw Arm for my loading apparatus but I read Both AAshto and ASTM Methods but I cant find anything on either that say its required. I can't find anything that remotely says a screw arm was needed... Does anyone have any idea where in these methods it says we need a screw arm?

Automated equipment uses 'stepper' motors to apply the load, controlled by a load cell.

The disassembled remains of an old T&O concrete compression machine comes to mind. Actually, I think the consol equipment was also T&O, but a mind can be a frightful thing to put to use.
Actually, the old equipment consol was extremely versatile.
The present equipment is quite limited in how the tests are run and require some real thought if doing testing 'outside the box'. I have gotten back much of that versatility by going to automated consol and direct shear machines.

Now I used to have an ELE version for my consol that had a screw arm underneath the loading arm to suspend the arm before the intial loading on to the sample. Although i found the part convenient I still dont understand why my equipment requires it. Specially when I could not find it in either ASTM or ASSHTO. Unless I missed it and if I did does anyone know where it is in either ASTM or ASHHTO books?

My rule has always been---Show Me!! Prove Yourself!!
I remember an experience with CCRL a few years ago. Do to timing, we ended up with 2 inspectors, to get our lab checked in short order. They got into an argument , over something inconsequential. My techs loved it. They left, not speaking to one another. I was expecting a minor addition to my bill ... the price of admission to one of the best side shows in the area.

AMRL must be assuming that a screw arm is the only way to accomplish this because their own inspection worksheet only states that Load Device "permits quick application of a given load increment without significant impact."
