Topps asphalt sealcoats parking lots, roads and
while offering crack filling and parking lot
can be applied to an asphalt surface by hand squeegee, machine
squeegee or by sprayer. Typically, driveways are squeegeed while
parking lots and roads are sprayed after first being trimmed by
Over time asphalt binder is exhausted and the
aggregates begin to unravel due to the absence of the binding
cement. Sealcoating helps to delay this process when
applied properly. The rate
of pavement deterioration depends upon the traffic volume as
well as climatic conditions. The next step is the development of
minor cracks which widen and deepen with time. If the cracks are
not repaired at this stage, water seeps into the base courses
and damages the pavementís load bearing capacity. It is
evidenced by rutting, shifting, and serious alligatoring. The
pavement then must be either overlaid or completely removed and
reinstalled, depending on the condition.
When applied correctly, sealcoating
should last for three to four years and should never be applied
every year. Sealing the same asphalt surface every year will
cause the sealer to form a build up, or a hard shell like
surface over the asphalt which will start to crack and crumble.
This will shorten the life expectancy of the asphalt surface
requiring more extensive asphalt repairs.
Silica sand will always be added to
the sealer to help improve traction in rainy or wet conditions.
