Inquiry #5: Section 39-1.03B “Design Air Void requirement for RHMA G is 5.0.” The OBC must be greater than or equal to 7.5% based on total weight of mix.” This is a huge problem; currently industry is fighting this in the super pave specifications and the newly issued RSS for section 39. Local asphalt producers cannot meet this spec with available locally available aggregates. As an example, typical combined absorption for aggregate from one supplier is 1.0% to 1.5%. Absorption of asphalt is 65% of the absorption of water. At 5.0% AV, the design criterion is unachievable with locally sourced aggregate. Please advise.

Inquiry #6: Per Add. 2, Section 13 of the Special Provisions has been deleted. Will contractor be required to obtain Railroad Protective Liability Insurance? Is the state compensating the railroad for railroad flaggers that may be required? Please advise.
Inquiry submitted 03/04/2013

Response #1: Railroad flagging is not anticipated. Section 13, "Relations With Railroad" of the Special Provisions was deleted through Addendum No. 2, dated March 1, 2013, because the planned work is outside the railroad Right of Way. Refer to Section 5-1.36C "Railroad Property" of the 2010 Standard Specifications.
