FOAK request

If one were to order 14 tonnes of 'road scalpings', what would one
expect to arrive?
1. Chewed up old tarmac.
2. Something else.

Your answer could decide the fate of a Welshman....

 

"Another term for ?road planings? i.e. material removed from the
reconstruction or rehabilitation of roads by means of a planing
machine."

Round here I always thought scalpings was the same as Type 1 Limestone
chippings - makes quite a decent hard surface if laid properly. Paving
Expert somewhat disagress with me though:

Something else. Type 1 MOT to be precise.

Kill him.

 

Free weed seeds.

I got a donation of some pre loved road surface a couple of years back and
with it some weeds that I had worked 20 years to eradicate.

Type 1 MOT, its a purple mixture of rocks ranging between 10 and 40cms in
size
when you compact it, its hard as nails.

 

That's what I was expecting. However, what I got was a regional
variation of type 1 MOT, as mentioned by Krusty which is, in fact, much
better suited to the job in hand.

Even though the Welshman appears to have done me a favour, I am minded
to kill him anyway.

 

The regional variation is part of the deal - it's basically just a term
for quarry waste. Down here in Wiltshire it's nice stuff - limestone
chippings with some clay in it which binds together nicely when it's
compacted. But it depends on what your local quarry is producing.

 

It is, inasmuch as MOT stands for the same thing with both the vehicle
test and the Type 1 aggregates.

 

Ministry of Transport, because it's approved by them for use in road
building. It does sound weird the first time you order some.

 

Ministry of Trade. It boils down to there being a british standard for
the type of stone and the minimum/maximum size of the bits (ie what size
sieve the quarry put it through).

 

I mean, Ministry of Transport.

 

So we're talking serious boulders here?

 

Indeed. I lived in the Wye Valley and we used scalpings on the drive. The
stuff from Livox Quarry by the Wye at Tintern was lovely stuff. Reddish
brown muck in with the stones, compacted well and no mess. The stuff from
the other side of the watershed at Drybrook was horrible. Red clay in with
the stones that made heel of a mess. Fine as aggregate for roads but not
what you want as the top dressing.

 

Perhaps he meant mm.
This stuff is in the range 40mm to dust, and appears to be a mix of
granite, slate and crushed concrete.

 

Scalpings:
Fine gravel to dust, literally scalped up from under the machinery
at the local quarry.

Road Scalpings:
Either Scalpings as above, used to fill the gaps and aid compaction
when the stone/gravel base of a road is laid OR Chewed up old tarmac.

It depends if you are talking to a road builder or a resurfacing
contractor.

Doh! mm

 

Yes that sounds more reasonable, sounds like an excellent way to dispose of
toxic waste / spent fuel rods and the like, just mix it all up and flog it
to unsuspecting punters to spread on the driveway.
Who is ever going to know?

 

Never heard those two words put together...

This would be planings....

(What we call) Scalpings are 'dirty' stone aggregate that isn't really
good enough for 'proper' work but is OK for back fill etc. Sort of all
the crap from the quarry. It doesn't usually contain anything too big as
they put it through a sieve to try and rescue to bigger stuf to go back
though the crushers.

MOT type 1 is a sub base for road building. Sort of one up from
scalpings. Better than scalpings but these days they are allowed to put
recycled concrete into it; as long as it's clean and passes the tests
for sub-base aggregate.
