Whereas rubber pavements for childrens' playgrounds is not
that practical either. They still can scrape their skin and the rubber
is hot in summer months.
Here, we use sand or saw dust from the trees. My daugther's school
had rubber pavement prior to switching to saw dust, and now there are
far less injuries.
There are some bylaws (as YOU certainly can imagine) about ...
Thus, a small "self-propelled" caroussel had be demolished: 10 meters of rubber ´plates around it would have collided with the historic pavement in front of the historic townhall ...
Protected historic buildings etc in towns are another reason for not using such, btw.
I wonder if the pavement in Washington, DC, a location that gets some very hot weather, is somehow different in composition from the pavement you are mentioning, Walter, that high heels sunk into. If it isn't different, then it seems the Washington folks messed up on their research.
Well, they are made the very same way, you can get them in different classes, very soft, soft, harder, very hard etc for every purpose and reason.
But all are rather soft compared to stone - the hardest something like soft aspahlt.
