All petroleum products will disintegrate asphalt .
Sealers are resistant to gas and oil and prevent their seepage into
the surface below. Individual
aggregate pieces or stones work loose and come out, leaving
roughened surface and additional pockets to hold water, oil and
gasoline. All driveways,
secondary streets and parking and airport areas are subject to such damage.
Sealing Saves Money For The Owner
Asphalt sealing is important preventative maintenance, and
saves the owner much of year to year repair costs.
Like most good maintenance practices , the regular sealing and
protection of asphalt is economically sound.
An owner can have a quality sealing job put down at small expense,
and secure as much as 300% greater life on his asphalt surface.
Such treatment is far less expensive than repair and re-surfacing
work.
Sealing Protects Against Frost And Snow Damage
Sleet, Snow, and frost
accelerate water damage. In
addition, the freezing and thawing increase the pavement and sub-surfacing
damage.
Sealing Protects Against Sunlight Damage
Sunlight will, over a period of time,
oxidize and dry out the binder, causing revealing of the aggregate.
Sealing Protects The Surface Against Porosity
All asphalt pavement are
porous and absorb water. In
freezing weather these pockets of water turn to ice and the resulting,
expansion and contraction will damage the pavement. If this water soaks down
into the base, it will soften or erode the base creating air space so that a heavy load on the
surface will crack the pavement. Rain
then causes water to collect in these depressions and flow down through
the cracks or pot holes to cause greater damage.
Sealers Beautify Asphalt Surfaces
By adding a long lasting
black satin finish, a sealer will add beauty to any asphalt surface. Some
street and highway departments use colored coating on pedestrian walkways to
direct traffic and outline safety zone. Obviously, too, colored coatings are
ideal for tennis courts and decorative parking areas such as those used to
accent landscaping and architectural design on motel, commercial and
industrial sites.
Sealing Reduces Pavement Maintenance Cost
In day-to-day maintenance, a
sealed surface is smoother and requires less sweeping and cleaning.
Leaves, cigarettes and debris don’t stick.
Snow and ice do not lock into tiny depressions, making snow plowing
and ice removal faster and easier.
