Mix Type/AC Grade

is the "C" Oil necessary for 15 approaches that are roughly 10' long and crossovers that will be removed before seeing a winter? The cost increase for the cold-weather benefit for "C" oil vs "B" oil will not be seen in this application. Will an addendum be issued for this or are you open to discussion of a change order after bid?

Generally the 9.5 mix design would be utilized for just the top 1.5" and the 12.5 would be used for the bottom 4.5" but this seems to be switched based on the table on sheet 4.

RE: Mix Type/AC Grade

There will be an addendum forthcoming to address this.
