Abstract

Deicing chemicals, such as Sodium Chloride (NaCl), lowers the freezing point of water, resulting in less skidding, less hydroplaning, and more friction on roadways. NaCl has limitations regarding its deicing capabilities; therefore, a supplement should be used to decrease corrosion and aid in lowering the freezing point of water. Incorporating AMP in NaCl brine aids in bonding to the road’s surface and further lowers the water’s freezing point. This study was conducted to explore the optimum solution of AMP and Sodium Nitrite (NaNO2) and the impact 20% fly ash has on durability. Hardened properties were used to compare the impact of AMP. Durability was determined following ASTM C-666 and BNQ-2621. Results indicated minimal losses in hardened properties or scaling resistance with up to 15% AMP. The freeze-and-thaw results indicated a decrease in resistance in the durability factor when the cement was replaced with fly ash according to ASTM C-666.
