Lime water anyone?

[Lehaut]

We are getting it warm here in LA, not as much as those who live down south.  The heat has a bad effect on the roads, as it tends to melt the tarmac. (I assume you can add something to raise the temperature when laying roads in "tropical" regions?)  It also makes pedestrian crossings near invisible.

Anyway, here they are painting some roads white here (lait de chaux)  in an attempt to reduce the effect, a bit like painting the inside of railway lines to stop them expanding too much.

Have not driven on one yet.
