The draft policy indicates that the buried approach slab would typically be installed on a gradient of 5% to 10%, but there is little to no discussion on how to choose the gradient AND there is no discussion on any complications that may arise based on the GRADE of the highway approaches. I would imagine that most bridges would have approach grades of between 0.5% and 3%, so there would likely be minimal complications due to grade, but for steeper approach grades, some additional guidance or considerations may be appropriate.
The cleat may also benefit from a note advising that it must be built on a specific gradient to match the approach slab gradient (it may be obvious, but best to err on the side of too much information instead of too little for less-experienced contractor staff).
