Refined Coal tar based sealcoatings when applied at the
recommended rates to asphalt pavements:
- Protect the Surface against Water, Frost and Snow
Damage. Unprotected asphalt surfaces are sufficiently
porous to allow water to seep into the base courses. The water
softens the aggregate and reduces the overall load carrying
capacity of the pavement. More severe damage is caused by
the expansion of the trapped water in the pavement during winter
months. The freeze-thaw cycles create large cracks and the
problem is steadily worsened. The sealcoating forms an
impervious barrier that does not allow the water to seep into the
pavement, thus protecting it
- Protect against weathering. Asphalt binder in the pavement
is shielded from ultraviolet rays.
- Protect against attack by petrochemicals and deicing salts.
- Beautifies the asphalt pavement and improves its value.
- Saves money for the property owner. Like most good
maintenance practices, the regular sealcoating of asphalt is
economically sound. An owner can have a quality sealcoating
job done at a 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. The commercial
property owner will enjoy lower snow removal costs on properly
sealcoated lots due to a smoother surface.
