Revision history [back]
The Russian Military used PSP - Perforated Steel Planking (also called Marston Mat) to build airstrips in Afghanistan - this is probably the best solution - Faizabab airstrip used to be (maybe still is) all PSP, and Bagram's aprons were all the same. It's the same material that is sold sometimes as 'sand ladders' for 4x4 vehicles, but was designed to interlock. Not sure where it could be sourced, but it is possible that some of the Russian material has now been replaced at airstrips and might be available.
