Rust leaching from the rebar
« on: October 26, 2011, 12:32:52 PM »
Anyone on the Forum know if this is serious?

Quote from: Cambridgeshire County Council Online forms Report a highways fault - Ref. 1156466
Road name, number or path name (if known): Busway (Southern Section)

City/town/village/area: Cambridge

Location: Within 200 metres N & S of Long Road bridge.

Type of problem: Roads and pavement surfaces

Enter fault details

Further description:

Whilst cycling on the adjacent maintenance track/cyclepath/footpath I noticed a considerable number of incidences of rust leaching from the rebar in both the vertical (guidance) and horizontal (wheeltrack) surfaces.

I have no specialist knowledge of structural engineering issues, nor of your regime for inspection, but thought wrong not to bring this to your attention, especially in the light of the current legal dispute between the County Council and BAM Nuttall.

I've alerted Cambridgeshire County Council (above) just in case.

Here are some of the photos which I took on Mon 24 Oct 2011.

Photo 08 shows evidence that CCC are looking at the cracking.

Please note:

All photos were taken from the adjacent maintenance track/cyclepath/footpath: no trespass on the busway itself was involved.

I noticed this (along with cracking and imperfections in the concrete) on the Southern stretch on opening day, and sent photos to an engineer I know.

He felt that the concrete was of poor quality and might not last long before needing substantial repair.

If cracking appears associated with the rust patches, that will be very serious.

Where was that, Mr. Worm?  My runs along there yesterday (bar one return run) were in darkness...
