I am using a topping slab to remedy an access ramp that was improperly designed to ADAAG Standards. It is an exterior location on southern Oregon coast. We might have a freeze once a year but no frost to depth - lots of winter rain. Do I bond the new 3" (to a max of 6")topping slab to the old ramp? Do I need to use WWF or would fiber be okay. I am matching all control joints in old slab.
