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…
I did a talk to our graduates recently on pavement design with a construction director, I did the technical bit he did the money / risks bit. Directors don't get to be directors in a LTD company without merit. For those of you mentally compiling a list of¬† directors without merit,¬† just ask yourself if they were good for the company, ie made money?

It's not that its complicated to understand as you still end up with thicknesses of layers, it's the choice that complicates. In this choice matrix are grey areas, the largest is…
Running up to Christmas, just had company Christmas lunch, do you notice when the loud music starts the older guys head for the door? I am part of that congregation. Anyway I am old enough to remember digging sand replacement densities in lean mix and wondering at the mysteries of comparing them to a theoretical density. Then there used to be a minimum strength, then a minimum and a maximum, then if my memory is correct, a minimum again. Whether it was the blacktop lobby or a diminishing amount of long greenfield road jobs, the good old leanmix was no…
