Roads (PART 2)
Are you ready to find out even more about how our roads came to be? Just continue reading below!
John McAdam was the first ‘modern’ road builder and gave his name to the Macadam surface in the 1800s. His brilliant innovation was realising that roads did not need massive stone foundations. By ensuring that the top stone surface was made with stones smaller than the tyre width he innovated a smoother running surface, but there was still a dust problem. Eventually, someone took the top surface and mixed it with tar and leaving us with a tarmacadam road, that’s tarmac to you and me.
Thanks to the introduction of tarmacadam roads we had a road on which our vehicles could perform their different functions. But as we moved into towns and cities we needed to something to separate people from the road. For this, we used the raised pavement. Pavements have been around since Roman times but began to play a necessary role as our towns and cities became busier with vehicles. To protect the edge a solid granite kerb was added. In fact, if you look at a kerb you will most likely see black tyre marks upon it, visible proof of the job the kerb does in defending the pavement!
