This document includes all aspects of materials, installation, stressing, and corrosion protection levels for grouted post-tensioning systems. Requirements for field personnel are also stated as the knowledge of all involved contributes to building durable structures. The aim is to have this new Specification adopted by most State Departments of Transportation (DOT), simplifying the approval process for the systems used in different areas of the country while allowing for local environmental conditions. Also designers will find this book useful in preparing the Project Specifications. The purpose of this document is to establish a unified, nationally recognized specification for grouted post-tensioning. It is intended to apply to buildings, bridges, storage structures, and other structures using grouted post-tensioning tendons, except as follows: stay cables and rock anchors that are already covered by other PTI documents.
