Hi Abdulaziz,

in this changeset and some others,  you changed some road surfaces to "unpaved" that had been "paved" or "asphalt" before, e.g. the Eko Bridge https://www.openstreetmap.org/way/133795072/history

Here, you actually had added "paved" before, and then changed it to "unpaved" later: https://www.openstreetmap.org/way/133795083/history

For some roads like the Ijora Causeway
https://www.openstreetmap.org/way/133766199/history
you added "surface=unpaved" where there was no information before, but it probably should be "asphalt". 

In all of those examples the Bing images look quite a lot like asphalt to me. I suspect you accidentally copied that "surface=unpaved" to a lot of roads. 

Could you have a look and clean this up? 
If the Bing images are trustworthy, I could also help with the cleanup.

All the best, 
and thanks for making the map better!
