any info on bikable "sand-seal" shoulder surface (NC) - Cycling Mob: Road Cycling, Mountain Biking and More

06-14-2004, 10:51 AM

There are a couple re-surfacing projects contemplated in New Mexico
right now where the design engineers are considering some type of
"sand-seal" surface treatment for the shoulder. The idea is that
having a "dirt-colored" shoulder provides visual separation from the
traffic lane, might slow traffic a little since it would make the road
look narrower, and if done "properly" would provide a smooth
high-friction bikable surface.

The problem is that none of the NMDOT engineers have ever specified or
used a sand-seal treatment, and dont know exactly what to do to create
a good surface for bikes. All they know how to do is horrible
"chunk-and-seal."

I found some specs on the NCDOT website, which leads me to believe
that they may do this type of surfacing.... My question to ya'll is
whether it is a good ridable surface? feedback on this?

anybody have any other examples, specs, or feedback on a
"dirt-colored" shoulder that could be installed adjacent to a
"regular" asphalt traffic lane without affecting drainage or creating
an unbikable grade separation?

thanks,

Dan

nothing? nobody has encountered colored asphalt shoulders anywhere?

In certain areas of Massachusetts, I've seen _huge_ green shoulders
on a freeway. I believe it was route 2 or 190, north/west of
Worcester, or route 290. The road is two lanes wide, with probably
two to six lanes worth of green pavement on one or both sides.

In considering why they exist, I figure it may be for future
expansion and/or snow removal (gotta put it somewhere!). They appear
to be painted green, not dyed, and some areas have faded a bit, but
they get the point across that it's not an area to drive on.
