17. Reference Bid Item A0380 Removal of Asphalt (500 CY), Drawing B6, Note 1: Exactly where can we potentially expect this 500 CY of asphalt to be located? Is it in the 10” thickness of existing roadway that will be pulverized? We don’t see how this item can be quantified due to the varying thickness of asphalt on the project. You say it can be incorporated into the recycled aggregate base, but if it is not in the 10” of roadway that gets pulverized it won’t meet the graduation. Please give additional details.

The Contractor is advised to review all available information including the plans, Special Contract Requirements, and Pavement Report/Geological Boring Logs. Bid item A038 is intended to cover asphalt removal outside of the existing typical roadway section. Payment will be made for the actual quantities of work performed and accepted according to the contract. See Subsections 109.02.
