This break for removal project located in Gulfport, Mississippi, highlights Antigo’s ability to meet very tight schedules and to effectively break concrete in multiple pavement layer situations. Though not a large project, the requirement to break the concrete quickly was very important to the prime contractor. The need to break and remove the upper layer of concrete while preserving the underlying asphalt and concrete layers added to the complexity of the project.
Antigo used two guillotine-style Badger Breakers® and worked long hours to achieve the high production required by the prime contractor in order to complete all of the runway reconstruction work during two 30-day shutdowns, one for each runway end. Antigo completed its work in 2 days during the first phase and in 2.5 days during the second. Antigo broke the 11” thick concrete down to 18” minus size by striking the concrete on 12” centers. This upper layer of concrete was removed without damaging the underlying pavement layers.
Antigo completes dozens of break for removal projects at airfields every year. Each project has its unique challenges but Antigo has been very successful in providing the required equipment and skilled operators to meet these challenges.
