Pothole information from our local councillor, Gary Crookes:

Temporary pothole repairs:

This is the shovel of tarmac in a hole approach. It was useful when the number of holes that kept appearing meant that for safety purposes we had to fill as many as we could. Now that the rate of formation is much lower (because of the better weather) we now only undertake temporary repairs where the hole is in a road that is due for more extensive repair or where it is in the middle of a busy road or junction and more planning is required for traffic management purposes. The reason for this is that a permanent repair takes 20 - 25 minutes and a temporary repair can be done in a fraction of that time. Although a number of temporary repairs have failed, the majority are still in place.


Permanent pothole repairs:

This is for isolated or small groups of holes where the overall road surface is generally sound. The process is that we cut out a square, remove all loose material, tack coat the sides of the hole to provide a water tight joint, fill (in layers of no more than 40mm thick) and compact. We have divided the city into 6 areas. There is an inspector and two pothole gangs allocated to each area and the inspector works ahead of the gangs identifying the defects which the gangs then repair. It is hoped that in 3 months all serious/dangerous defects across the city will have been dealt with (either through a permanent or temporary repair). Holes of an inch or less, unless they look likely to develop into a bigger hole) will not be dealt with as part of this exercise.


Resurfacing:

Where the road surface is in poor condition, no pothole repair is likely to last long. The options (for which programmes are currently being developed) are:

Plane and Patch - a planing machine removes the defective area (to a minimum depth of 40mm) and a new tarmac inlay is laid and the joints sealed. This is used where the road surface is variable and has been used recently on roads like Princethorpe Way, Nod Rise and Woodway Lane. Ideally, roads that have been patched in this way will be surface dressed (see below) to waterproof the repairs and therefore help increase the life of the patched carriageway. Surface dressing also helps to remove the 'patchwork quilt' effect.

Overlay - a strip of carriageway is planed out adjacent to the kerbs either side of the road and an overlay of around 60mm thick is then placed on top. Ironwork (manhole covers etc) are adjusted to the new levels. The exact thickness depends on each road and the overlay material is usually 'polymer' modified to increase flexibility and therefore reduce cracking. This method has the advantage of reducing the amount of waste and it increases the thickness of the road surface. Examples are Banner Lane and Charter Ave. Likely cost around £10+/sqm (will depend on location, thickness of overlay etc).

Retread - this recycles the road surface in-situ with new bitumen being added to rejuvenate the old road surface. A contract is being tendered for this year's programme. Expected cost around £19/sqm.

Resurfacing and Reconstruction - the last resort as this involves digging out and rebuilding the road. Costs will be well over £100/sqm.

Preventative Maintenance:

To protect roads that have been patched and to prolong the life of those roads which are approaching a critical state (but have not started to fail), surface dressing is a low cost technique that is widely used elsewhere (and used to be in Coventry). It is essentially the application of tar and chippings which waterproofs the road surface and thereby offers protection against the formation of potholes through freezing and thawing. It also helps restore skid resistance and can improve the appearance of roads which have been riddled with utility trenches etc., Typical cost starts around £2/sqm for side streets. Other preventative techniques include microasphalt which can help improve the ride quality of roads and control cracking.
