In this project the pavement application of slag cement was used for durability, strength, ASR mitigation, and lighter color. Achieving close to 28-day flexural strength in 7 days 620 psi avg flexural strength. 28-day flexural strength of 700 – 750.
This is the first time slag cement was used in a Wyoming paving project. This is the first project Jacobs Eng said FAA has allowed slag cement in this Region.
This was a removal and replacement of the existing runway for the shared Wyoming National Guard and Cheyenne regional airport.
