There is some bias to what this man is saying. however he is kind of right. Nigeria doesn’t have the maintenance culture needed to deal with bituminous road. yes they are cheaper, however they required constant maintenance, of which the government can’t afford and fail to do. however concrete road cost more to do, but are more durable and require less maintenance. Moreover since we have a thriving concrete producers in the country. we would be reducing the need to import bitumen needed to fix road. we would be keeping capital within the country.
