    No idea how much this would cost, but just shows what could be:

    Get a hydrophobic bike and you would be all set.

    I have very, very, very little hope that I will see any main roads repaved near me any time soon. And by soon I mean in the next 12 years. It seems like investment is a dirty word, make do and mend is the only choice local councils are left with. We are heading back to 19th century surfaces, not ideal for my carbon velocipede.

    Almost like installing properly designed drainage in the first place then? But without the overhead of the regular suction pressure washing that will never happen (like drain maintenance rarely happens until the drains fail to deal with the water headed through them)

    Exactly – however my point was that the fact that it does drain itself is not a problem. Proper drainage off an impermeable surface needs careful design of the road (shape, structure and material) but I agree it’s a more of a one-time thing and not the repeated technical cleaning this surface would need.

    Interesting point about the frost from P3t3- but i’d imagine there are some practical issues with fully impermeable surfaces as well (e.g. shape) – not an easy one to get right for all conditions either way..

    Actually I think they already use it, isn’t this the stuff that sometimes evaporates from where they have laid it – the surface goes through and then in a matter of days its through to the old planed surface underneath.
