Concrete Paviors 3:1 Plan Ratio

Factual Questions
1

Has anyone here ever seen anything like this? Concrete paviors with a 3:1 plan ratio. I took this picture in Toronto, on Yorkville Avenue between Yonge and Bay.

All the stuff I can find on the internet merely talks about the aspect ratio - that is, the length divided by the vertical dimension, what I would call the depth, but what they call the thickness, noting only that 3:1 or less is required for vehicular traffic.

All I can find regarding the plan ratio simply notes that 2:1 or 3:1 can be set in an interlocking herringbone pattern … fine, but why not a 4:1 plan ratio? Would that make the aspect ratio silly, or unsafe, or uneconomic, or what?

Are there any advantages or disadvantages to a 3:1 plan ratio relative to a 2:1 plan ratio?

Here’s some “narrow” pavers. http://www.stepstoneinc.com/narrow-modular-pavers.htm?section=0&ind=12
This guys are like 6:1
Some of the pics show the different tones in a messy fashion… attemps made to make patches but they aren’t even the same shape…

Maybe the home owner has an OCD wife and he wants to make her run away ?

Can’t help you with the issue of making them look neat - why not ? As long as its precisely integer ration … 6:1 or 4:1 or something… you can tessellate (the use of a repeating pattern ) it somehow.

For anything you want or need to know about choosing and laying paving, I strongly recommend this website (I have no connection other than as a satisfied user)

http://www.pavingexpert.com/home.htm

It is a British site but has many North American contributors and most things apply equally on both sides of the Atlantic.

Probably anything over 3:1 would break under load
