Styrofoam for embankment fills

[BigH]

Okiryu - further to my comment in the open forum, send me your email and I will forward a number of articles and refernces I collected in the past - I gave a talk in India on the use of lightweight fills. Styrofoam is interesting in that 1 m of soil is in the order of 70 m of styrofoam. It does float, though, and that has to be taken into account - but in some cases like this, a system of pvc pipes tied together vertically have been used as well.

Like Ron said, I, too, have used light weigth foamed "concrete" (Elaztizel) on a job and it worked out brilliantly.

Thanks BigH. I just sent you an email... appreciate the support!

@Okiryu....as you've noticed, BigH is pretty awesome. Take five years of his experience and you have an entire career of most engineers!

 

[Okiryu]

Hi Ron...yes, if I just could take a little bit of the experience and knowledge from all the great engineers in ET, it will be awesome !

Also, on cellular concrete, you can specify a permeable mix that helps offset buoyancy.

Lightweight foamed glass aggregate. Not sure of other areas that it is available.

I'm late to the party, guess that is what I get for taking the weekend off.

We have used EPS blocks for a couple of designs under roads. Works well, just have to make sure it doesn't float on you. Be careful during construction; we had one start to float on us when it was about three-quarters complete.

Instead of trying to develop support parameters for the EPS, I would place a meter or so of crushed stone between the EPS and the pavement. That way the pavement design isn't dependent on the EPS. This will also help ensure that there are no point loads on the EPS which could over stress the material.

we are also about ready to deploy foamed glass aggregate on a highway job too. Aeroaggregates does have resilient modulus values for their product.

I have only used it to lower the earth pressures on a residential retaining wall which had a car porth above it. One thing to remember is to cover your expanded light weight fill with 1000 gauge polythene as petrol, diesel spills can dissolve it

Okiryu - haven't forgotten - but it might have to wait to the weekend - see a few posts I am making today!

Okiryu,

Just sent you today (30 Jan 2020) a presentation I made on lightweight fills at IIT (Kharagpur) and separately about 15 refernces. Let me know you got them.

Hi BigH, I received all your references. Thank you very much !

Ron - did you receive the email?
