Abstract:
To achieve the Department's goal of completing construction projects in a timelier manner, it is essential to use products which decrease installation time and effort over conventional materials. CLSM is used primarily as a self-leveling backfill material and does not require compaction. It is much lower in strength than concrete, making future excavation possible. Due to the self-compacting properties of the material, construction personnel and equipment are not required in confined spaces for compaction operations. As a result, the width of excavations can be decreased, laid back slopes eliminated and flagging operations reduced. The NYS Department of Transportation is implementing Trns.port SiteManager, including both Construction and Materials functionality. Implementation of standard AASHTO software enables SiteManager to allow revising business practices to be more consistent with industry-accepted best practices. The revisions to the Standard Specifications are to conform to SiteManager's methodology in defining its Material Codes and Pay Items.
