960-1 Description.

This Section covers all post -tensioning (PT) systems and components remaining in a completed structure, including temporary erection PT left in -place and permanent PT for design capacity. The submittal for approval of PT systems must use materials and components meeting the requirements of this Section and Section 462. Submit PT system shop drawings to the Engineer f or review and acceptance in accordance with Section 5. The PT system shop drawings must include component drawings, system drawings, and test reports. The acceptance of a PT system for use on the project is based on the exact major components, as defined i n 960-2, that were used in system testing and that are shown on the approved PT system shop drawings .

960-1.1 Material References: Meet the requirements of this Section and the following:

Epoxy Compounds* ................................ ............Section 926 Bar (post-tensioning) ................................ ..........Section 933 Duct Filler for Post Tensioned Structures* .........Section 938 Reinforcing Steel (mild) ................................ .....Section 415 Parallel Wire (post -tensioning) ........................... Section 933 Strand (post -tensioning) ................................ ......Section 933 *Use products listed on the Department’s Approved Product List (APL).

960-2 Component Standards.

All PT system components must be materials compatible with the filler material and installation process used to encapsulate the tendons. The component materials must not chemically degrade during the service life of the structure. The service life of the structure is 75 - years unless specified otherwise in the Contract Documents . The following are major components and must be marked with the manufacturer’s name, trademark, model number, and size corresponding to catalog designation: an chorages, bearing plates, trumpets, caps, duct couplers, connections, “O” -rings, heat shrink tubing, duct, and local zone reinforcement. Any of these items that cannot be marked must be contained in packaging or appropriately tagged with the necessary info rmation. The following are examples of common off -the-shelf accessories and need not be stamped: bolts, washers, inlets, outlets, drains, ports, valves, plugs, nipples, hose adapters, and grease. Substitution, modification, or deletion of any major component of the PT system, excluding local zone reinforcement, after system testing and approval by the Engineer is not permitted. Provide only PT systems utilizing tendons completely encapsulated in grout or flexible filler filled anchorages and ducts. Do no t use systems transferring prestress force by bonding prestress steel strand directly to concrete. Embedded anchorages for bars are permitted. Strand or strand-tendon couplers are not permitted.
