Problem
Preliminary testing has indicated that the ice melting capacity of various deicing products may vary significantly, even within specific deicing product categories. In addition, states’ processes for procuring deicing materials limit competition, are subjective on performance, and can become increasingly burdensome for lab, procurement, and management staff.
Objectives
To provide transportation agencies with an objective, repeatable test procedure for measuring the ice melting capacity of deicers.
Results
For this project, the Mechanical Rocker Test Procedure, developed by Nebraska DOT, was evaluated for use as a national standard. As of 2024, this test method has been provisionally approved by AASHTO.
