yea right - concrete would be ate up so quick!! thats why peoples garage floors and frost lips get torn up before their asphalt driveways! and thats just from parking their cars on it and having the salty water drip off, let alone if thousands of cars were driving on it and the salt was being poured onto it directly! lol like i said - if concrete was better, they wouldnt use asphalt since they already use concrete under it and then put asphalt over it, they would stop using the asphalt and save money
