WA and Cal ? triax have a wheeled damper boom off the stern - connection so far unseen, haven't scoped one at rest - limiting weight bounce and rock motion. A third wheel apparently doesn't limit bounce.

lotta dig n fill goes on here taking limestone from holes inland to near Gulf property...the triax traffic ripples plastic pavement but generally the pave recovers

the design shown may also be a tubular boom attached to a simple 2 wheel carriage.

frost depth...low or no frost depth doesn't expand water gone below the cracked surface seal thus lifting the cracked areas. Once cracked patches are lifted then the total force applied to road surface is no longer spread over the total adjacent road surface but impacted...like a hammer...along the open edges and downward.

Once the surface patch disintegrates, hammering continues down thru the loose subsurface expanding the hole outwards ...

the process is heard as an excuse to NOT patch the hole until the entire area is $hot as patching the hole only leads to more impaction thus larger hole.

I suggest engaging great skepticism when reading Duane's claims about
what I've said. Then ask for my original statement in context.

Although I'm a Mechanical Engineer, not a Civil Engineer, I'm well aware
of that fourth power rule for pavement damage. I can't imagine what
Duane is, um, imagining, or mis-remembering.

BTW, perhaps four or five years ago, _Bicycling_ magazine had a very
good article on asphalt pavement, going pretty deeply into the mechanics
of its degradation and failure. It didn't get into mathematics, but it
was an unusually informative article for that magazine.

Unfortunately, I didn't keep a copy; I passed it on to the Civil
Engineering professors where I was teaching at the time.

For Bicycling, it's amazing. For actual information, it's pretty
content free.

A lot of hogwash too. The claim that roads were paved because of
bicycles is a bit much as apparently the first paved road on the
planet is in Egypt. Built 4.600 years ago. Long before a bicycle was
even a gleam in anyone's eye, Egyptian quarrymen were hauling large
slabs of stone over a paved road.

In the U.S. the earliest paved road seems to date back to 1625. It
was a colonial city street in Pemaquid, Maine.

The first asphalt roads in the US were in Battery Park, 5th Avenue in
NYC in 1872 and on Pennsylvania Ave, Wash. D.C., in 1877.
