The Dallas-Fort Worth International Airport (DFW) is the ninth-busiest airport in the U.S., with nearly 1,000 flights arriving and departing daily serving over 69 million travelers each year. Aircraft take off and land from seven runways, all of which are the original runways from the airport’s construction in 1973. Airport officials determined that Runway 17C-35C was in need of replacement, and a CSDA contractor was chosen to provide a solid surface for takeoff and landing. Dual rider saws from Lissmac make part of the over 115,000 square yards of cuts to remove the damaged portions of Runway 17C/35C at DFW.  General Contractor Austin Bridge & Road headed up this massive project. Over 115,000 square yards of runway and taxiway needed to be removed and replaced without damaging the adjacent runways or damaging the substructure. This included replacing the Portland Cement Concrete (PCC) keel along with some taxiway replacements for a total shoulder reconstruction. Austin Bridge & Road called on CSDA member Diamond Drilling & Sawing Company of Denver, Colorado to assist with the runway removal and replacement. Non-destructive testing methods were used by DFW officials to determine that there were many damaged concrete panels on the runway in need of repair. Airport runways are costly and logistically challenging to shut down, so a method to quickly and efficiently remove the damaged runway sections was needed. Concrete sawing with diamond tools was the chosen method, as this method would protect the underlying structures and base under the Portland Cement Concrete Pavement (PCCP) from damage. Additionally, sawing the runway into sections that could then be removed, allowed the damaged sections to be removed quickly and would not require the base material to be replaced. The sawing portion of the project commenced on May 24, 2018. The first step in this process was to cut the PCCP into sections that were able to be removed by the general contractor. These sections measured 8.3 by 8.3 by 1.5 feet and weighed approximately 16,000 pounds. Husqvarna 7000, Husqvarna 99HP and Lissmac 138HP Diesel slab saws were used to make these cuts. Blades ranged from 20 to 48 inches and were purchased from Diamond Products and Lissmac. Once the sections were cut, they were removed by excavators. All slurry on the jobsite was removed using vacuums. After all cut sections were removed, the general contractor...
