Scott - I have no vested interest in this - I'm a Civil Engineer but work for a Contractor in a railway environment, not highways but have worked in both Consultancy - designer, as well as Contractor, highways and now rail.  

I can assure you, our parent Company Tarmac and my employer Griffiths would dearly love the Highways Authorities and Councils to insist on road resurfacing! However - with budgets as they are with LA/ County and local councils a bridging repair needs to be completed or we'd have no roads to drive on at all..

As for your comment of 'bit desperate'. Thanks - I'm trying to provide some basic engineering and safety justifications for use of surface dressing based on 32 years in the Civil Engineering industry and my professional qualifications not some frantic googling..

#11, 7WotW,

Is this for the wheel arches, or the new road surfacing? Smile

Nobody wants to pay more Council tax but everybody wants better services - I'm sure Liz Truss will find a way . Or blame somebody else . 

It's a tough gig, having been in the bizz myself . Education and adult social services cost gazillions , and stretch budgets to breaking point Every engineer I knew would have loved to have had carte blanche to resurface very road which needed it but it's a pipe dream , and not helped by the accelerated wear  caused by everybody thinking their life is incomplete without a two tonne SUV.

I'm quite happy with little Railway Bridges rather than bloody roads...

I just tried to drive across part of Northamptonshire and the roads were just plain dangerous. One un-repaired road was so degraded (I assume by farm vehicles) that 20 mph was too fast and I had to use both sides of the road to avoid the collapsed surface. It was just like the earthquake damage in the middle of Sicily.....Really unpleasant drive with Brixworth blocked by roadworks and lack of signs Furious Also had four `blind` drivers attempt to force me off the road and finally had a hose leak most of the coolant out!   Still, tomorrow is another day......Or is it? Silly

Nice call that; just fitting new wings and had thought about underseal. Cheers, Ed

The road at the end of our lane, Dereham Road, North from Hingham, Norfolk, was resurfaced with loose chippings less than 3 weeks ago. 

I've avoided using it until today. The literally loose chippings are now all but gone but there are already shiny and bare patches on and into bends and old holes and bumps reappearing. 

I accept this is cheap but won't accept that it's cost effective against a proper resurfacing, it just slows down the dilapidation a little.

The thing is, I very much doubt that our council would have any evidence to show that it is cost effective; in 12 years I'm not aware of any road that's been 'resurfaced' in any other way to enable a comparison.

I'm sure the contractors have 'evidence' but I'm equally sure it's a case of never mind the quality, feel the width!

As for your reaction to my comment about the 'improved friction coefficient', well I'm an engineer of many years standing, also quite qualified. Give me the technical explanation, quantified, on this improvement in friction, when the stuff is first laid, after a month, 3 months etc. I'd love to see that research. 

And maybe the reasons for needing that improvement, because if it's not needed it's not a benefit.  

Anyway, your comment about it being a bridging repair says it all and confirms the early comments about sticking plasters etc

Scott. TRL published the enclosed design guide for road surface dressing.


https://www.trl.co.uk/Uploads/TRL/Documents/Road-Note-39-(7th-Edition)---Design-guide-for-road-surface-dressing.pdf
 

Section 7.3 covers parameters for the selection of materials, 7.3.1 specifically skid resistance of a road in that surface dressing may be utilised to improve the skid resistance.
