Generates more tenders over time due to maintenance.

It seem like is more expensive and more maintenance prone.
from AI:
For road and high-traffic areas, asphalt is generally the preferred choice because it is more cost-effective, faster to install, and more flexible than pavers, making it better at withstanding heavy loads and continuous vehicle movement. While pavers offer better traction, especially when wet, and a more customizable aesthetic, asphalt's ability to provide a smooth surface and its efficiency for large-scale projects make it the standard for highways and commercial areas.

Not to mention as riot and crime ammunition - Ian Cameron being asked to visit?

Slightly more seriously high quality concrete paving bricks / blocks are used for industrial loads, particularly with turning movements of heavy vehicles and loading equipment (forklifts). Snag is that the paving is not impervious so water seeps in and this can result in settlement and/or the "pumping" of fines. Once set, blocks are not easily lifted so trenching etc invariably results in untidy areas. Blocks are also relatively impervious to the spillage of hydrocarbons that would dissolve the bitumen in asphalt. Definitely more expansive and slow to construct particularly if the specifications for the bedding and jointing sand are followed (they often aren't).

I would hope that they are industrial quality as the thinner and weaker bricks and blocks, including clay pavers ae more suited to decorative or "designer" paving in light duty applications; light motor vehicles only.

I'll give you half a guess as to what type of pavers these are.

I'm still intrigued by the choice to go with Paving over tarring.

I used to work in Braamfontein a while ago and at the time, some areas were being prepared as pedestrian only zones at one time. Not sure if it something like that.

Given that there are road markings and pedestrian crossings in the new paved surface I doubt it.
 
I think the reason you do this kind of road is because it looks nicer. I cant figure out another reason why it was done this way.
