ICPI compaction requirements

[neversatisfiedj]

Anyone have a link. I am still using Wacker 1550 but if they raised the compation# , then I guess I will have to upgrade.

[neversatisfiedj]

From Tech pec 10 - I answered my own question

Once the pavers are placed in their specified pattern(s), they are compacted into the bedding sand with a plate compactor. The compactor should have a minimum force of 5,000 lbs. (22 kN) and frequency of 75 to 100 hz.

This is for vehicular traffic I believe though. I am questioning rather to change out my 1550 for somwthing bigger.

Any thoughts seasoned VETS ?? I just use the 1550 for patios - no vehicular apps.

Pretty soon their going to recommened using a 20 ton dual roller!


Honestly, i got to see how they how the heck i am going to a large compactor. Got to look for some deals on ebay.

After taking ICPI, i do not think my wacker 1550 will cut it for much longer.

[neversatisfiedj]

There is the one Chris uses on there going cheap. My 1550 is only 2 years old though ! And I compact in 2 inch lifts so I think I will be ok.

[kkls2006]

While we are on the subject of ICPI, I was wondering how tuff the level 1 cert program was to complete? I'm scheduled to take the two day coarse on the 20th & 21st.

Anything I should know b-4 I get there?

Thanx for your help

Haven't looked at the ICPI specs in some time, but rather than reccommend minimum sizes on compactors, why don't they recommend maximum lift hieghts for a given force range??

IOW- 2" lifts for 3-4k compactors, 3" lifts for 4-5k, etc, etc, etc???

[neversatisfiedj]

Thats what I'm saying D Felix - I do 2" lifts with my 1550. I would love a reason to get one of those 7000# reverible units though.

I have seen these on ebay and similar ones http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=019&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=290080968469&rd=1&rd=1

They may not be the best out there, but they are affordable. i have seen them even cheaper too. Lets face it the tamper gets very little ours compared to a lot of tools. I for one can not afford 6$-$8k for a good reversible plate right now but i know i need one.

[bigviclbi]

Northern tool has one for about $2000.00 thats big and reversible. I wrote in a thread asking about it, and got some feedback to be wary of it. But if you search the forum someone from iowa bought one and loved it with no problem. I just won an ebay bid for a 1 year old lightly used 1550 for $750.00 though so someone else will have to test the one from northern tool.:)

[mrusk]

I saw that tamper on ebay this morning. I wonder if its made in china or soemthing. There has to be a reason why its so cheap.

Tampers to seem to get used very little. Seems like a need a huge job to blow through a tank of gas in my 1550 in a week.

You should check ICPI again. The latest info I have is that compaction will now be 98% proctor and they recommend a 7K# compactor for base and 5K# for pavers.

That tamper on ebay is sold from central NJ. It also has like 6800# of force too. I am sure its from china or somewhere. I bought a 10" wet saw from harbor tool and freight last year for making my bullnose cuts. $200 with the stand and a 1year replacement guarantee. That thing works great. i could buy 3 of them for the price of a MK. for what little bit of use it gets it should be fine. I would never buy something from china that i use everyday, but those tampers are tempting.

[GroundScapesIncorporated]

Most of what ICPI says makes good good sense, but ill have to honestly admit, I feel as though 2" lifts with a 3400 pound compactor is fine and also fine for the pavers. And 98% proctor? I have never heard of a problem if 95% was achieved.

My opinion? What is it? not much. no scientific studies anyway.

[neversatisfiedj]

Well it seems the majority is using the 1550 like myself. I guess I will keep it and do my lifts in 2" intervals. I worry more about the soli compaction with the 1550 than with the modified stone. Maybe in '08 I will upgrade for a huge tamper. Chris I think that ICPI spec is for vehicular traffic applications to use that much force bu then again you are certified and I am not. I just read it not that long ago.

I just took the course a few weeks ago here in jersey. You are correct. They were stressing left and right how you really should own two compactors..one for base to do in 4" lifts (7k) and one for pavers...although I thought I remember them saying 3-4k for pavers...I could have that wrong.

And as for the 98%...I didn't hear anything on that. Just the 95%standard/modified for walkways and other light residential and the latter for drives and high traffic (commercial) areas.

[greenbottle27]

Really, how many of you guys out there are doing proctor density testing on your joe blow residential paver jobs??? So what the big difference between 95-98%...... pleeeeeease?! Maybe if you have fine clay soils you might be concerned but for us here in South Jersey you're getting 95-98% as an industry standard from us :)

How about you say, it's 3-4k# for pavers with a 5k#max.

[cgland]

How do you know? I used to think I was getting good compaction w/ the 1550 until I got the 2540A and had a job tested. I rammed the crap out of my base w/ the 2540A at 3" intervals and I just made 97%. I could have acheived 98% if I had a tad more moisture in my aggregate. It was an eye opener. For as hard as I hit that base I thought I would be 110%. LOL All I'm saying is that you don't know for sure untill you get tested. And since we have been I have a better idea as to where my base is.

Chris

[greenbottle27]

Chris - based upon regular spot testing in conjunction with using a 7k# plate in 3-4" lifts and a 2 ton roller when necessary... you're getting the 95-98% industry standard from us. *lol* Yes, maybe I got 94.9999% on my walkway at home since that was not tested... but I;m saying you can't test every single job. Well, you can, IMO though, that would be a waste of $. but like you said unless you do get tested you truly don't know what your % is. An eye opener it is :o)

Chris

Just out of curiosity, what was the 1550 achieving with the smaller lifts?

[cgland]

orion - I don't know about the 1550. We only got our first job tested when we got the 2540A. I'm sure you can get close as long as you are going over it like 4 times in different directions w/ proper moisture levels @ 2" MAX.

[IHI]

Help...- This hardscaping is a tad bit new to me. Can someone explain the process or steps invovled to complete what you guys are talking about. Oh yeah, please also mention who test the compaction, etc.. and how much it costs. Does everybody follow the ICPI requirements?

[bigviclbi]

[NewHorizon's Land]

IHI --- Im new too but I looked at the ICPI website and EP HENRY website and I got an idea. PM me and I can help with as much as I know (not to much)

[NMS0219]

I have one of those compactors from northern tool. I love it. That thing has been indistructable. Its way over build for what it does. I also have one of their compact plate compactors great machine. I only put a spark plug into it and i've had it for 5 years. I also have one of those wet saws form harbor freight. Works great and at $200 you cant go wrong. We use it every day during the install season. I did have to put a belt on it. The belt cost me $5
