High Performance Airfield Pavements (HPAP) Dec 2013 NAVFAC NavAir Facilities Command
"...Economics of the Technology: ROI or Payback
The ROI for a single JSF high temperature concrete VL pad was calculated to be 8.15. Expanding value to the ten vertical landing pads that have already been built increases the ROI to 49.96. These numbers take into account the extra initial investment to build and maintain the pads for 30 years compared to having to constantly replace the pads if conventional concrete is used. The ROI for the ASR [Alkali-Silica Reactivity] part of the project is 36 based on the extension of an airfield pavement life from 12 years to more than 60 years....
...Site Implementation and Specific Applications
Thus far a total of ten high temperature VL pads have been built at Eglin AFB, Duke Field, MCAS Yuma, and MCAS Beaufort with another being planned at MCAS Iwakuni. Simulated carrier decks have been built at Duke Field and MCAS Yuma with another being planned at MCAS Beaufort. ASR mitigation techniques are being implemented on all Navy concrete jobs.
As of now the concrete mixes have performed well under laboratory testing. A limited number of vertical landings have occurred on some of the high temperature concrete VL pads and there still has not been damage caused by the JSF...."
