March 23rd – The towpath resurfacing between Walsall town centre and Bentley Mill Way continues, as I noted earlier in the week, tarmac is being laid on top of compacted ballast. It’s a nice enough surface, but I’m still bemused by the pointlessness of it all.
Today I passed as they work crew were filling a butty with hot asphalt, ready to spread and roll. The ease with which it tipped from the excavator bucket and the steam that billowed suggested it was very hot indeed – and it made me wonder how it was heated – in the yard or from the place it was produced? I suppose the limestone grit it’s made from has quite a high specific heat capacity, so it must hold heat awhile.
One thing I always love about hot tarmac is the smell. It’s one of the really strong smells I recall for some reason from my childhood, and one sniff of it and I’ back in the schoolyard.
Funny how smells do that to you.
