Funny you should say that, it IS exactly the same colour

but there is no sign of burning, so doubt it. ... or were you kidding?

If it was melted wheelie bin, I would imagine it would start to become plastic using the heat gun. It could it be a thermoset resin like P38 body filler or the resin used for glass fibre, these wouldn't become plastic, just char if you get the temperature high enough.

When you heat plastics they often give off a characteristic odour. I'm not suggesting you sniff it, but did you notice any particular odour when you heated it? P38 and glass fibre resin both smell of styrene which is quite a sickly smell, whereas wheelie bins smell more like when you take black bags off a roll (not really sickly at all)

There was a smell - hard to describe though other tahan 'plasticy'. Pretty sure it's a spillage though as in some places there are trails of small drops.

Hammer and chisel?

It sounds like it's either melted plastic or some sort of thermoset resin spillage...whichever it is, solvents won't touch it, so it will have to be some sort of mechanical method. Chipping or abrading.

If it's brittle, then chipping away (tediously) with a cold chisel and hammer will probably be the best way. The colder the day, the better.

You haven't said what the drive is made from. Concrete? Tarmac? Block paving? Concrete will probably be ok, Tarmac is soft and will be damaged and if it's block paving...just replace the blocks!

Ah yes, i haven't. Sorry! .. it's conrete. Just ordered a scutch hammer as they're cheap enough (£10), hopefully it'll improve the process.
