http://trustart.org/projects/109-bamboo-bikes This caught my attention during the week, this is entrepreneurial Americans at their best. I am no lover of America or Americans but this project is just superb. Now we need bamboo towers that when properly anchored can support a turbine. http://news.bbc.co.uk/1/hi/8257153.stm see above link if you think I was dreaming. Everything is possible If the "system" allows…
http://www.highwaysmaintenance.com I have been visiting this site for years and found it useful, it occurs to me belatedly that I should share it with you. That is those of you not erudite enough to have found it. Particularly you divots that continue to call blacktop /asphalt concrete, ----TAR. Click on the site and learn. If you have used the word TAR out of context in 2010 then I give you a resolution, stop your sloppy language and be precise. It can only help you go further professionally and stop me metaphorically belting the back of your heids.…

Well if it is I would like you to listen to the link below http://www.bbc.co.uk/iplayer/console/p00c4pmk/The_Climate_Connection_The_Climate_Connection_2010_Debate_Whats_Stopping_Us…

You would expect, if you lied on a post or your observations on a company or institution were way off the mark that said companies or institutions would take some legal action against you¬† or at least robustly comment on the maligning words. Well given the recent reaction to¬†one of my¬†posts,¬†some people are as sensitive as adolescent school girls.¬†¬†It surely must be¬†wrong to associate a personal post on a personal blog to the persons employer and apply pressure regarding one's personal opinions. So here we are in Scottish /¬†Burmese state where words must be constrained, not because they are wrong,…
Well I have been biting my tongue for months, not like me ! the resignation of TIEs chief executive David Mackay was too much for a balanced view to withstand. I am not a Edinburgh tax payer, if I was I would be driven to protest. Bilfinger Berger are a construction company, they did not make the overly complicated bespoke contract that they signed up to. If it is exploitable it's the fault of the spec makers, TIE. To state on resignation that a company who cannot legally reply, due to the contract,¬† are delinquents, and lets take that in…
I can see the searches people put in to reach my site, and a recurring one is "density of type 1 subbase".¬† So in my humble option you should use 2.1 / 2.2 t/M3 for aggregate that has a relative density of 2.7 / 2.8 t /M3.¬† Limestone will be less in proportion to it's relative density as will granite, and some igneous rocks will be more, such as from Hillhouse Quarries in Ayrshire whose relative density from memory is 2.9 t/M3. the lack of facts¬† is we don't routinely measure subbase density as a criteria so there is not…
I went to a presentation tonight on the concrete ambassador series of four talks throughout the UK, Professor Karen Scrivener gave the talk on "cementing the future of concrete - science & sustainability" She ably demonstrated that concrete was needed and demanded as a unique material worldwide and went on to get us to the nana technology that enables them, the scientists, to tell us, the users and practitioners how a better understanding of the material and its constituents can deliver concrete with less CO2 emissions. It is the constituents that hold the key to CO2 reduction along with techniques…
The post on Osprey diary 7 includes some remarks about Spey bay, I was at our laboratory for the Fochabers by pass, so could visit Spey bay during spare time. The reason I had spare time was our lab was being assessed for accreditation by UKAS assessors, and I was the virtual spare person at a wedding. This, because my assistants were the builders and I was the architect, so well done Jamie and Sandy, master builders. Everyone who has achieved UKAS accreditation knows the difficulties, so I would like to thank John Macavoy, chief materials engineer¬† for the M74…
It cannot have escaped any drivers notice that the severe winter has caused sudden deterioration in road surfaces. The concrete section of the M90 was no exception where the fast lane was under traffic management for some weeks due to the micro surfacing¬† not being there any more. The micro surfacing (slurry sealing?) was a complete success as I watched it being applied with some wonderment, it did give a smoother and quieter ride, and the joints from slab to slab did not cause cracks, what was that wonder material?¬† I don't know. However the repairs to these extensive areas…
The post title is a book title by Joe Moran, not finished it yet but can still recommend it to you folk interested in our roads' history. This author is not dilatory when it comes to detail, it is crammed with it. I did have to point out through his blog spot that a central reservation is a central reserve, mere pedantry I know but how often can you correct a University lecturer? Hope he doesn't read this as I will no doubt have made several grammatical errors.…
I had a meeting today with a newish testing lab in Scotland. CET Safehouse have arrived in the small marketplace in Scotland, and¬† have a tool that the others do not have, Internet reporting.¬† An evolved system, some five years in the making, not only does it act as a an electronic booking in system but it also has the worksheets and the report sheets integral to the whole system. In CET safehouse's system they transfer into your inbox your checked and authorised results, this means you can pick up your results as fast as they produce them. UKAS…
I did deliver my pavement design talk to my senior colleagues on two separate occasions this week. Fortunately my stumbling performance was politely received, my highland hosts have an imbued politeness, which contrasts with my part weggie assertiveness. (Pure dead aggression, bye the way, know what I mean?) To the talk, my spreadsheet brings together everything I put in text, and highlights, "where's the money". I have set it at 80 MSA¬† as that would appear to be the "design" standard adopted by Transport Scotland for most trunk roads. Perhaps so, if you have the money, order the best you…
