[ NCHRP 20-07 (Research for AASHTO Standing Committee on Highways) ]

  Project Data
Funds: $69,980

Effective Date: 5/11/2012
Completion Date: 3/29/2013

NCHRP Project 25-25(04), Environmental Stewardship Practices, Procedures, and Policies for Highway Construction and Maintenance, was conducted to develop a compendium of practices for integrating environmental stewardship into construction, operations, and maintenance activities (see note below).  This final report on the project contains 11 chapters addressing different aspects of environmental stewardship practices for highway construction and Maintenance.  Chapter 8 of the report, Winter Operations and Salt, Sand, and Chemical Management, identifies recommended practices for strategic planning for reduced salt usage, and looks at initiatives by leading DOTs, and practices and accomplishments in specific program areas to achieve such reductions and improve environmental outcomes. Although Chapter 8 provides the foundational elements that guide the development of environmental management systems and environmental strategic plans for state DOTs, many of the strategies contained in the chapter, particularly those in Chapter 8.3, Strategic Planning for Reduced Salt Usage, need to be updated.  NCHRP Project 20-07/Task 318 was conducted to prepare an updated version of Chapter 8 to replace the current chapter in the final report for NCHRP Project 25-25(04).  The project is complete.  The final report consisting of the revised chapter and a summary of the work performed to update the chapter has been forwarded to AASHTO staff to make it available to the chair and members of the AASHTO Highway Subcommittee on Maintenance and other interested parties.  NCHRP staff will coordinate the actions required for incorporating the revised chapter in the final repot for NCHRP Project 25-25(04).  (NCHRP staff: Amir N.
