Sand does sound easy and more socially acceptable.

Not only that, it seems to have worked wonderfully well.
Thanks for the tip Colin, I would've never thought of that solution.

I have to say, I'm not sure how long it would have taken me to come up
with it, and I'm supposed to know about such things.

Why are you supposed to know about such things?

Because, over the years, I have done a lot of analysis of friction and
also the effects of debris and wear in what are often complicated
mechanical systems. I am even doing some at the moment.


I suppose casting defects could be an issue.

It makes me wonder how many road repairs are due to poorly built manhole
"shafts" sinking and crumbling. Winter seems to hit them badly. We should
make more use of the pavements.


Outside of built up areas what is wrong with poles. I appreciate the wires
or fibre version can be damaged by wind,thieves ,branches etc but by
putting them in ducts under the road which openreach are doing for many
sections it seems that the communication industry is increasing its
reliability at the expense of those that use the roads.
This road I use regularly is an example, used to have a pole run but now at
regular intervals you have some closely spaced man holes like this set.

In some places they are already sinking and the road breaking up around
them so the journey on what was once a reasonable road is now thump thump
thump every few hundred yards.
And when they do need attention Murphy and his mates have to set up the set
of traffic lights for a couple of days and hinder everyone whereas one time
a man or two in yellow or earlier a green vans quickly stuck a ladder up
the pole and got it done fairly quickly.

They should be ducting them ALONGSIDE the road instead of under it.
However I presume that that'd mean extra cost in paying farmers for the
right to do so. Long term that might well work out a lot cheaper than
keep repairing the roads ... especially if you took into account wasted
time for people using the roads.
