Research Idea Scope
Snow and Ice Control involving different deicing products including sodium chloride (salt), magnesium chloride, calcium chloride, calcium magnesium acetate (CMA), potassium acetate
(KAc), and agricultural products such as corn or beet derived Ice-Ban. An NCHRP project, 2002-F-03, to compare the environmental impacts and performance of de-icing products was submitted and was listed as continently approved. (If it does not proceed, inclusion in this study would be beneficial.)
Cleaning of paving equipment with petroleum or alternative products with consideration of procedures to manage residue.
Concrete sealing with different organic sealers
Vegetation management with herbicides under guide rail and around signs

NCHRP Report 577,
Abstract: TRB’s National Cooperative Highway Research Program (NCHRP) Report 577: Guidelines for the Selection of Snow and Ice Control Materials to Mitigate Environmental Impacts (published May 2007) explores guidelines for the selection of snow and ice control materials through an evaluation of their cost, performance, and impacts on the environment and infrastructure. The report examines a decision tool for the selection of snow and ice control materials to suit the specific needs of any given highway agency, a purchase specification that can be used by an agency once agency staff have selected materials for use, and a quality assurance monitoring program that includes procedures and standard test methods to characterize snow and ice control products before their purchase or use.
