Runawayslow against median walls or in gravel shoulders?

Cellular concrete, aka: foamed concrete.

I spent several years designing and building the equipment, developing the production process and overseeing the application of it for a number of projects in N.A. and Europe. Although cellular concrete has been around for about 80 years, we perfected some design elements of materials, process and equipment and did a number of highly innovative things. I never did any runway runaways, although we did pitch that application a few times. IIRC, LaGuardia has such an installation.

 

I agree with the motion that you need to slow down and select the correct gear before you start down a mountain pass. If you take a hill in top gear then you're a idiot asking for a accident.

That baing said, the motion of blowing your airhorn in hopes of others getting out of your way is completely stupid. If you have directional control of the truck; ditch it somewhere.

 

well, first off, if you notice on the downhill, trucks are restricted to the two right lanes, why, because they are slower traffic, and the signs also say slower traffic keep right. Before you begin the downhill, there is a sign that says trucks must use the two right lanes. Secondly, and I hate to say this, but if you loose your brakes, those vehicles in front of you might become collateral damage, there's no way around it sometimes.

As for your idea. What happens if your car breaks down/gets a flat and you have to pull onto the shoulder? What happens in the winter time when the shoulder is 4' deep with snow? The actual truck ramps are costly to build, super cheap to maintain. Hell, unless a truck uses one, there really isn't any maintenance. Although, CDOT is rebuilding one of the ramps on Wolf Creek, they are making it deeper, narrower, and realigning the entrance to it.

Now if we could just the 4-wheelers to stop taking a pick-nic break at the entrance to them.
