Can you imagine walking through an airport and seeing these hats on Air Warriors across the country. This could be the start of a real movement, something that could make America truly great . . . . . . . you get the idea
Nice.
Take the rest of the day off...with pay...and put yourself in for a NAM while you're at it.
I am?
Cool beans!
I'll take a couple two tree of those hats!
Yes- Engineering Materials Arrestor System (EMAS). Pretty much wet concrete.
The maintenance process is complicated but really quite fascinating. You need to keep it wet, so that means crews gotta go out there with hoses and a water truck about every couple hours. The water trucks for this are bright orange so that they don't get confused with fire trucks.
The crews not only have to have SIDA badge training with vehicle endorsements, but special training on the wet concrete process because you can easily overdo it but if you don't do it right then the EMAS concrete starts to set. There is also a balance with ambient temperature, wind, and humidity- conditions vary a lot different between NY in the winter, to the dry southwest, to elsewhere.
Speaking of the winter, remember how a lot of runway and taxi lights are LEDs nowadays but they found the snow builds up around those? (The old incandescent lights always made enough heat to melt the snow that fell on them.) Well the EMAS at cold airports has to have heating elements underneath that concrete. So much for all that electricity savings.
Something else, they also have those big rakes like what you see at baseball stadiums for the baselines.
The catch here is the EMAS is too deep for regular footwear. Instead, the the maintenance crews have to wear special footwear that resembles snowshoes in form and function.
So complicated, but definitely worthwhile...
Haven't been here for a while and this is why. The above post is BS. EMAS is crushable concrete. Have another beer and go back to bed.
