Seal Coating
Research has demonstrated that properly applied (and
properly timed) seal coat can save the property owner $100,000 or more —
over the life of a hot mix asphalt pavement. But what does seal coat actually
do that results in this substantial savings?
In spite of its excellent adhesive and waterproofing
properties, asphalt has some serious drawbacks that relate to its chemical
makeup. Asphalt is a very complex mixture of thousands of chemicals which are
predominantly open chain (aliphatic) in structure. The open chain provides easy
access to weather, salts, and chemicals to attack and disintegrate
the asphalts molecules. When this happens the asphalt in the pavement loses
much of its original properties, such as binding and waterproofing. 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
pavement’s load bearing capacity. The
damage will continue if proper protective actions are not taken. So it highly
cost effective when pavements are preserved by a "protective coating"
that resists attack by the elements that can destroy asphalt.
