00592.30 Personnel Qualific ations - Provide supervisory personnel to oversee the placement who
are qualified and approved in writing, by the rolled membrane material manufacturer. Submit written qualifications to the Engineer for approval . Do not begin rolled membrane installation until after approv al. Construction
00592.40 Pr eparing Existing Bridge Decks - Prepare the entire deck surface, including the deck
edge against the curb, to receive the membrane. Remove all grease, oil, paint, dirt, laitance, rust, and all other contaminants that would affect adhesion of the rolled membrane. Perform surface preparation according to Section 00504, modified as follows: After remov ing the existing asphalt concrete wearing surface according to Section 00503 , ensure the deck is smooth and free of obstructions. Clean the bridge deck by thoroughly sweeping and blowing compressed air immediately prior to placing the Emulsified Asphalt tack coat. Class 1 Preparation according to 00504.41(b) is not required. 00592.41 602 00592.41 Placing Rolled Waterproofing Membrane :
a.Ge neral - Do not begin membrane installation until qualified supervisory personnel and, all Materials and Equipment necessary to perform the installation and any required repairs are at the Project Site .
b.W eather and Other Restrictions - Place Emulsified Asphalt tack coat, concrete patching, and waterproofing membrane when the deck is dry, the air temperature is between 40 °F and 90 °F, and the surface temperature of the deck is 40 °F minimum and rising. Do not place Emulsified Asphalt tack coat if the surface temperature exceeds 120 °F.
c.Handling Materials - Store membrane indoors at a temperature between 60 °F and 120 °F until it is placed on the bridge deck. Do not allow t he membrane to sit in direct sunlight longer than necessary.
d.Area of Application - Apply the membrane starting at the low point working to the high point. Protect adjacent surfaces from spatter or coating. On Bridges without curbs, apply waterproof ing membrane from outside edge to outside edge of the deck, or within the limits of the AC wearing Course. On Bridges having approach slab s with a sawcut and joint sealant end joint s, extend the rolled membrane 5 feet beyond the bridge deck onto the appro ach slab . On Bridges with cur bs or concrete rail, place a 12 inch continuous membrane strip, after applying Emulsified Asphalt tack coat, so that 2 inches is placed vertically along the curb or rail, with 10 inches placed horizontally on the deck surface.
00592.42 Installation:
a.Tack Coat - Place Emulsified Asphalt tack coat as follows:
1.Concrete Substrate - Place Emulsified Asphalt tack coat as shown or directed and according to Section 00730. Extend the tack coat 2 inches up the face of the curb.
2.ACP Base Course - Place Emulsified Asphalt tack coat as shown or directed and according to Section 00730. Primer may be substituted for the Emulsified Asphalt tack coat on the ACP Base Course according to 00592.42( e).
3.Rolled Waterproofing Membrane - Place Emulsified Asphalt tack coat as shown or directed and according to Section 00730 .
b.ACP Base Course - Place a 2 inch ACP Base Course, according to Section 00744 or Section 00745 to provide a uniform surface on which to apply the rolled membrane. Construct the ACP Base Course using the same ACP specified for the ACP wearing Course, unless otherwise shown or directed.
c.Primer - Primer may be substituted for Emulsified Asphalt tack coat only for application on the ACP Base Course below the rolled waterproofing membrane, with a primer application plan, according to the following: When ambient temperatures are forecasted to be above 65 °F, follow minimum manufacturer primer cure times or allow primer to cure a minimum of two hours until the primer is sufficiently cured, as approved by the Engineer, prior to rolled membrane installation. 00592.80 603 Do not use primer when ambient temperatures are forecasted to be, or fall below 65 °F at any time during rolled membrane placement. Apply primer to cover a maximum area of 180 square feet per gallon on the ACP Base Course by brush, roller or as approved, to result in a completely uniform wetted surface, without puddling.
d.Rolled Waterproofing Membrane - Install rolled waterproofing me mbrane after the ACP Base Course, according to the following: Maintain 6 inches minimum overlap at all sides (longitudinal) joints or seams Maintain 12 inches minimum overlap at all end joints On Bridges with curbs or concrete rail, install the fir st roll ed section overlapped 10 inches onto the pre -placement strip Roll press all lap joints Stagger butt splices a minimum of 10 feet Prior to applying Emulsified Asphalt tack coat, roll press the entire membrane surface with approved Equipment Release any bubbles or pockets of trapped air or vapor and repair with mastic or as approved Sewn splices are not allowed
e.ACP Wearing Course - Construct the ACP wearing Course according to Section 00744 or Section 00745. Prior to placing the Emulsified Asphalt tack coat, and any ACP Course or waterproofing membrane, verify the underlying surface is free from loose rocks, or other debris. Clean the underlying surface by thoroughly sweeping and blowing compressed air immediately prior to placing the Emulsified Asphalt tack coat. Pave in the same direction as the membrane overlap end joints.

Provide all digital photographs in a format acceptable to the Engineer.
00592.44 Protection During Construction - Traffic is not allowed on the membrane without prior
written approval. Except for paving Equipment, do not allow Contractor Equipment on the membrane unless approved by the Engineer. Immediately repair any damage to the membrane caused by the paving operation, or other Contractor operations, with mastic or as approved by the Engineer. Complete repairs before resuming paving.
