M4 resurfacing shoddy job

    Anyone else notice how bad the new surface on the M4 between Kilcock and Maynooth exits is?

    It holds a lot of surface water.

    Looks to be a poor job and a danger in heavy rain. This morning you could see the surface has troughs where the water sits. and stops it draining away.

    Hopefully NRA or whoever paid for it hasn't signed off on the payment for this.

    I notice that my steering is wobbly on it also when I get above 120 or so. Fine on the old surface.

    Well given the speed limit, you'll never have to worry about that :p


    I think the new M7 surface is worse if I'm honest though, maybe it's just general cheapness in the spec?

    Yeh, lucky I don't go past 120 :)

    Think that M4 section is smoother to reduce noise to the nearby residents. Looks like they didn't get the base right.

    Any civil engineers like to comment?

    Its a new type of tarmac used, very shiny but super grip, looks lake a lake surface nearly.

    I'm not sure if it's the use of plastic as that's what some are using now in addition to the other materials.

    No need for that, I've found them all to be quite civil.

    It's so-called "Desert Spec" tarmac designed for very hot climates (eg the Middle East) - extremely hard-wearing but quite non-porous... Starting with the M50 widening project, the NRA specifies that motorway surfaces should contractually last 15-20yrs - or the contractor pays for any wear-related resurfacing needed below that - so this is what's been rolled out (pun intended) across the network as needed. As M50 users will be all too familiar, the downside is that it does not drain rainwater particularly well with huge volumes of spray kicked up whenever it rains. It's also lethal when damp conditions turn icy without salting or gritting.


    It's called "Desert Spec" for a reason, and a desert this country ain't...

    Would I be right in saying plastic is added? I know it is in other countries.

    It is lovely to drive on though.

    I'd imagine some form of resin (or plastic) is added to ensure it's very durable once set and has a high melting point - Bakelite is a plastic after all!
