Project Team

Owner: Cheyenne Regional Airport

General Contractor: Simon Contracting

Paving Contractor: S&S Builders

In this pavement project, slag cement was selected for its durability, strength, ASR mitigation and lighter color. Achieving close to 28-day flexural strength in just 7 days, the project boasted 620 psi avg flexural strength, with a 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.
