Concrete pavements and exterior flatwork generally provide excellent performance in all climates and exposures. Concrete durability is an essential component in delivering the return on investment that makes concrete an economical and sustainable material. In recent years, the industry has seen an increase in premature deterioration at joints and saw cuts in concrete pavements and flatwork in areas where winter storm events demand the application of deicing chemicals, which are most commonly chloride-based.
Table of Contents
1. Explain the mechanisms that link deicers to damage in joints in concrete pavements and flatwork.
2. Discuss different approaches to reduce the potential for damage.
3. Describe how this type of damage can be diagnosed.
4. Explain why modern structures may be more likely to be damaged by deicers.
5. Summarize AASHTO T358 Standard Method of Test for Surface Resistivity Indication of Concrete’s Ability to Resist Chloride Penetration and how it can be used to minimize the potential for damage.
6. Review the newly released ACI Technote ACI 201.3T-19.
