This course will focus on recent advances in our understanding of how chemical deicers impact the durability of concrete pavements. Designers, engineers, contractors, and owners should have an interest in this session. Recent changes in the use of chemicals for deicing and anti-icing have led to noticeable diminution in the durability of concrete pavements and exterior flatwork. New research focused on understanding the nature of the mechanisms associated with this deterioration may help develop new strategies for mitigation in the future.

The contents of this course include three recorded presentations from the ACI 2015 Spring Convention:
• Overview of Problems with Deicer Scaling Test Methods by R. Doug Hooton
• Effectiveness of Early Application of Penetrating Sealants by Daniel M. Vruno
• A New Look at an Old Problem: Reexamining the Saltwater Phase Diagrams to Better Describe Concrete Durability by W. Jason Weiss

1. Summarize recent technical information related to concrete durability and deicers.
2. Discuss how deicers present challenges to existing standardized test methodologies for scaling resistance.
3. Describe deterioration mechanisms associated with deicers.
4. Describe how deicers affect the durability of joints in pavements.
