2' Select Fill with asphalt versus Approach Slab
2' Select Fill with asphalt versus Approach Slab
(OP)
Why would a state DOT bridge engineer demand at least 2 feet of select fill with asphalt on the brige approach if the contractor opts not to pour an approach slab? Is the 2 feet fill a rule of "That's the way we have always done it" or is does it have something to do with impact reduction?

As to 2', there is already typically 1 foot of select fill under a typical concrete approach slab in most States. So another foot topped with asphalt doesn't seem unreasonable.
