Chip sealing is the most
economical method of
street resurfacing. It
is a commonly used
process by
municipalities across
the nation.
Chip sealing is
comparable to other
resurfacing methods in
durability and
effectiveness, but costs
far less, (15-25% of the
cost of pavement
overlays).
Chip seals are
economical surface
treatments designed to
protect and prolong the
lives of pavements.
Asphalt roads are like
the new paint on your
house. The moment the
application process ends
the deterioration
process starts. Much
like paint, asphalt is
subject to oxidation,
sunlight, rain, freeze
and thaw cycles.
Pavement is also subject
to a wide array of
different traffic loads,
use of equipment for
snow removal and
additional stresses by
normal ground movement.
Chip seals can be used
on new pavements to
increase traction, or to
prolong the life of a
pavement that is
structurally sound but
is beginning to age and
may have some surface
distress.
Benefits of Chip
Sealing:
| |
Improve surface
texture. |
| |
Waterproof the
surface. |
| |
Protect the
underlying
pavement from
oxidation, aging
and traffic
wear. |
| |
Give new life to
dry, weathered
surfaces. |
| |
Seal small
cracks and
imperfections. |
| |
Economic way to
resurface roads. |
The Process:
Chip sealing involves
spraying an asphalt
emulsion on the
pavement, then
immediately spreading a
layer of uniformly sized
aggregate chips. The new
surface is rolled to
seat the aggregate.
After a twenty-four hour
curing period excess
chips will be swept up.
