To follow-up on Peter's e-mail (from another engineer's perspective),
chip-seal is used for preventative maintenance - not to fix structural
roadway failure. So... if you notice potholes or significant roadway
cracking (and possibly alligator cracking) it is too far gone for a
chip-seal fix.
This is why it seems agencies are chip-sealing "good" roads. However,
what the agencies can control is the type of aggregate used in the chip
seal - because as noted by many riders, some of it is downright nasty
stuff.

Chip seal prolonges the useful life of pavements and seals very fine
cracks
in pavement before they get large enough for water and vegetation to
get
trapped in them. It is a good time for it. It should be done nearly
every 5
years.
I know it gets slick in wet conditions, but just giving you a pavement
engineer's perspective. Flame on.

Although that is true, as some of the roads actually were paved
within
the last few years, the road department will argue that this is
preventive. There probably is some merit to that, but how their
choices
are made is difficult to determine as there seem to be more deserving
roads for resurfacing. The good news is that it is very small chip
seal, and it is not that bad.

The nimrods that makeup Washington County Road Dept also chipsealed
the

roads
that were 'fixed' by chipsealing had no problems in the first place.
Well.. outside of the fact that a lot of bicyclists use them on a
daily
basis.
