Why are our roads being made with concrete bricks instead of asphalt?
I’m genuinely curious why are concrete bricks being used to build or renovate main roads instead of traditional asphalt?
As a biker, I personally don’t find these roads as stable, especially when the surface isn’t perfectly even. I’ve also noticed that when sewerage or rainwater stays on the road, the blocks can become uneven and the road starts looking quite disfigured over time.
Is there a specific engineering reason why this method is being preferred, especially for main roads with heavy traffic or it's just new method of corruption?
I’d really like to hear a different perspective on this. Are concrete pavers actually better in terms of durability and maintenance, or is there another reason behind their increasing use?
Also, is this mainly happening in Karachi, or are other cities in Pakistan using the same type of road construction as well?
