Wacker R1000B Compactor

[lumberjack1986]

I have a coming up where we are building a large house pad, approximately 5500 yards of fill is coming in. The specs call for lifts of 8" or less, the fill portion of the job is estimated to take 10 days (hourly job, customer only wants compact equipment on the job, spreading dirt with a CTL) and the compaction spec is 95%. The fill is SC/CL.

There is a $4k budget for the compactor rental. That's enough to rent a large compactor from United Rentals. However, last night I found this for $4.5k and am wondering if would work and add to my equipment pool.

Description listed: 2010 Wacker R1000B Hours: 452 40' Padfoot Drum Motor: Deutz Diesl Front Blade I don't think it's a 2010 as I believe they were discontinued a while back.

My thinking is 5500 yards/10 days= 550 yards/day 550/8 hours= 70 yards/hr 8" lifts means 70 yards/hr would cover 2500 sq ft/hr. The roller is 40" wide, so 2.5mph would cover 44k sq ft/hr, or 17.6 passes per hour. It would seem that's a fine safety margin, however I'm quite new to all this and am trying to get my ducks in a row. Anyone have information regarding that compactor and/or its suitability to the job?

I've never used a sheeps foot roller, and only seen a small remote sheeps foot trench roller used once when I was working in Statesboro GA, what kind of material are you using. When I built buildings we didn't really understand optium moistures, proctors, and LBRs, but now that I do roads for a living, a 95% modified proctor is easy to get unless material is saturated.

8" lifts should be easily compacted with that. Is it vibratory or static? Doea the dump pull/drive as well. It looks perfect for medium-large water line jobs (8-16") and small storm (upto 36")

Padfoots are for cohesive soils, the house pad is being made from SC/CL.

It's a driven, vibratory drum, machine weight is 4400lbs.

That's actually a pretty good weight and vibro is a big plus. I know sheeps foot rollers are used in Georgia where they use clay a lot. What is SC/CL, I'm not familiar with that term, is it a sand-clay, similar.to ball field clay?

 

[lumberjack1986]

SC is clayey sand, CL is lean clay with a low PI.


Here is a sample we took, should have the results today, we expect it to meet the design criteria.

That seems incredibly cheap compared to here in the UK! I think you've got a bargain there, that will come in useful for a long time. Always good to get more kit!
