Overbanding Question
Discussion
Some utility has recently done some works near me and made a very tidy job of making good afterwards, see picture below.
Most pot holes round here get filled with no overbanding so after a few wintry days the infill starts coming out due to frost and then the pothole reappears for another year... rinse and repeat.
The works below have no overbanding either so I expect them to start breaking up at the join this winter.
I know overbanding has been frowned on by motorcyclists and cyclists etc but as a motorcyclist I just treat it like any other poor surface (ironwork, white lines etc).
Question: Is it usual now to not bother with overbanding and if so for what reason? tia.

The Specification for the Reinstatement of Openings in Highways (Available for download if you’re lacking in exciting bedtime reading) doesn’t require overbanding. The requirement is to seal the vertical faces of the opening with bitumen to ensure a good bond and between the existing carriageway and the reinstatement.
Overbanding can help but the issue of motorcyclists skidding is a risk, hence the use of sealing the vertical face of the joint instead of overbanding. However, for this to work does require good workmanship….
I’d also add that looking at the picture, I can’t see much evidence of joint sealant.

I didn't know what 'overbanding' was so Googled it. I've seen in it a few places but reading further about the different types of repair, the materials to be used and how and the standards to which repairs should be done my observation is that:
A) Either contractors don't appear to be aware of them
B) They're aware and cut corners
in both cases knowing that
C) Rarely will their work be checked.
Which is correct?

Thanks. I've always thought that when repairing a pot hole they should cut back to clean/solid material, dry and clean out the hole with flame torch and vacuum, then paint with hot bitumen then fill, then roll, then overband. But round here potholes don't even have all the loose crud removed. Just a bag of cold fill poured in, tamped down and move on. So many are potholes again after a bit of traffic has gone over it makes me mad. Aside from the contractors being crap I can only imagine there is zero surveillance by the local council department. That won't be the case for all councils as I know some guys who are very diligent but not all.Overbanding can help but the issue of motorcyclists skidding is a risk, hence the use of sealing the vertical face of the joint instead of overbanding.

The picture I posted is the best workmanship I have seen for a long time, but as you say no evidence of sealing the vertical faces.
Without overbanding I can't see how water then frost won't cause crumbling next winter straightaway. Some overbanding has been designed to have a high skid index (?) to prevent skidding on it.

All 3 in my view :-)A) Either contractors don't appear to be aware of them

Where I used to live the council loved to lay overbanding in thick strips anywhere and everywhere making it an absolute nightmare for getting around on two wheels; having slid on the stuff a few times over the years (fortunately controlled and kept upright) I am now extremely weary about going over the stuff particularly when it has been laid on roundabouts and corners.
Where I live now they rarely repair the road surface at all and when they do - it needs redoing less than a year later due to HGVs to/from Dover chewing up the surface.

I find it annoying where there are is a new pothole within several previous patches that are failing. Now, the rational response would be to dig out the whole lot and replace with a large simple patch. In Northants, certainly and elsewhere it seems the reality is that the CBA contractor will heel a bit of spare asphalt into the deepest whole and leave the rest to create a worse scarry rash.

I don't get that either, why do they put a new patch surrounded by multiple existing failing patches. I honestly couldn't work like that. I'd have to take the whole lot up back to a clean cut and start again. Whoever is doing this crap work, and whoever is supposed to be supervising them need to be sacked pronto.Pothole repairs are different from utility reinstatements as they fall under different bits of specification. For potholes the process of just sticking some asphalt in the hole is supposed to be a quick temporary fix and then when the road authority has more time and can arrange traffic management they’re supposed to come back and fix it properly. Proper repair is to cut back to solid material, square off the edges, clean out and then spray up with bitumen to seal all the faces before laying the asphalt.
There are a number of reasons why this doesn’t always work, quite often it’s just down to money and the authority simply hasn’t got the budget to do any more than emergency fixes. However there is an issue with poor planning and an inability to understand whole life cost. Multiple pot hole repairs instead of whole scale resurfacing is a classic example of this as it’s dealing with the symptoms and not the cause of the failure and in the medium to long term is very expensive way to maintain a highway network.
Authorities who celebrate how many potholes they’ve filled are essentially celebrating an inability to think ahead and how they’re completely ignoring whole life cost. Not the smartest move…..
