Title:

Liquid Anti-icing Chemicals on Asphalt: Friction Trends

Abstract:

This set of experiments flowed from prior work completed in May to August 1999. The present research deals with tests which were performed on an asphalt surface between October 1999 and May 2000. Whereas prior tests were necessary to establish the reliance of anti-icing chemicals on temperature and humidity, this research was performed in an effort to better understand what effects these reliances would have on the road friction coefficient on asphalt. The environmental chamber was unchanged from prior work, with the exception that the sandblasted glass surface was changed to an asphaltic surface, which had been removed from approximately 15 years of service on a well-traveled arterial collector in Kamloops, British Columbia. Seventeen chemcials were tested in thid data set including CMA, CF7, CMA25, CMAK, Corguard 2000, CaCl 32 percent, Freezgard 0, Freezgard 0 with Ice Ban, Freezgard 0 with Shield, Freezgard 0 with TEA, Ice Stop 2000, Ice Ban with CaCl, Ice Ban with MgCl, Liquidow, Liquidow Armor, Cal Ban and MCP.
