Why are streets and parking lots often made of asphalt, but sidewalks of concrete?
I'm guessing it has to do with cost, durability, and/or smoothness, but I was just thinking about this question while walking to work.
BQ- Was this the best category for this question and if not, which would have been better? Why?

look at the safety side of it folks, asphalt drains allot faster than cement. puddles of water at 65 mph would be quite hazardous.

Asphalt is extra fee-effective than concrete, additionally asphalt fix is extra fee-effective than concrete fix. Asphalt fix could be pushed on interior of minute after repairing, unlike concrete which takes approximately 3 days to therapy. you could think of the varieties of street closure nightmares it would reason in the event that they had to close them down for 3 days at a time.

Concrete is smooth and comes in blocks and slightly expensive, Concrete roads are made of block and where they meet they tend to cause bump. Concrete block on pavements aremuch smaller and bumps are small and manageable ( if using prams etc )
