What causes asphalt pavement to fail?
-
Assuming that the initial asphalt pavement was designed and constructed properly, the primary cause of failure is the penetration of water into the asphalt base.
-
This process begins with the oxidation of the pavement surface which causes the asphalt to dry and become brittle, this leads to the erosion of the top layer of fine particles and the appearance of larger stones and small cracks on the surface.
-
If left untreated these cracks grow over time and eventually allow water to penetrate to the base of the pavement.
-
When water enters the base of the pavement the base material moves and settles leading to further cracking and an “alligator appearance.”
-
When the pavement reaches this stage the only option is removal and replacement of the old asphalt.
How Does Sealcoating Help?
-
Sealcoating seals the asphalt pavement, preventing and oxidation and erosion of the top layer of asphalt.
-
On older pavements sealcoating replaces fine particles lost from the asphalt surface due to oxidation.
-
Sealcoating seals the small cracks that can turn into large cracks and prevents water from seeping down to the base material.
-
Sealcoating helps protect the asphalt from the sun as well as the harmful effects of chemical spills such as oil and gasoline.
-
Sealcoating provides an attractive black surface that is ideal for painting lines and other markers.
-
Sealcoating leaves a smooth, clean surface which makes sweeping, cleaning and snow removal faster and more thorough, there lowering cleaning costs.
-
Statistics over a 15 year period show that a regular application of sealcoat results in maintenance cost savings of 42%-50% compared to similar unprotected pavement.
Pay Close Attention to Cracks
-
Because of the nature of asphalt pavement, your driveway will eventually experience some type of cracking. Cracks are the first sept in pavement deterioration. They allow moisture, chemicals, and the sun’s ultraviolet rays to penetrate the asphalt. This accelerates pavement breakdown. Proper repair of cracks ¼” wide or wider is the first step to successful driveway maintenance.
-
Cracksealing stops moisture from penetrating into the pavement and below the base.
-
Sealing cracks prevents foreign material/moisture to cause severe damage during expansion and contraction, which occurs with the rapid changes in weather in the Midwest.
What are Sealcoats?
-
Sealcoats generally consist of a mixture of emulsified asphalt, water, mineral fillers, and various other admixtures.
-
Sealcoats are applied directly to the surface of an asphalt pavement. They can be applied to rubber squeegee, broom, or mechanical spray.
-
Sealcoats serve to seal the top of the asphalt, preventing water from penetrating the surface of the pavement and protecting the top layer of asphalt form oxidation and wear caused by exposure to the sun and air. Sealcoats also beautify the pavement by providing a smooth, black, even surface ideal for painting lines or sweeping.
-
Sealcoats are designed for off highway use where there are low traffic speeds and tight turning radiused such as commercial parking lots, mobile home parks, schools, residential driveways, etc.
