Sealcoat is a mixture of emulsified asphalt, water, mineral fillers, and various other mixtures. Seal coats are applied directly to the surface of an asphalt pavement and is applied by a mechanical spray method. Some heavier traffic or commercial applications can also be applied by squeegee broom method. Seal coating works to replace the binder that holds asphalt together which over time begins to oxidize. Moisture can penetrate the asphalt and cracks begin to form. Sealing a parking lot or driveway prevents cracks from forming or premature oxidation consequently extending it’s life. Crack sealing and seal coating are well known ways to help preserve existing pavement and avoid costly asphalt resurfacing prematurely before it’s life expectancy calls for it. Repairing cracks early and using proper construction practice procedures, sealing will add life to your existing surface.
Annual sealing of heavy traffic area pavements, following instructions given by ACES and the manufacturer of sealing compound, is the best way to give your pavement a long and happy life. Although maintenance is good medicine, it is not foolproof, nor bulletproof.
What is Crack Filling?
Crack filling is a hot poured, rubberized sealant that is flexible, and is resilient to all kinds of climates. It bonds to asphalt or concrete and hardens quickly. It will not bleed through seal coat applications or driveways, however it must be applied properly. Crack filling is the pavement of materials into nonworking cracks to substantially reduce infiltration of water and to reinforce the adjacent pavement. Specialized materials of various minerals are designed to prevent intrusion of water and incompressible into cracks.
Long Term Advantages to Seal Coating Pavement
Seal coating prevents damaging effects of oxidation and water penetration. The Asphalt Institute states “The accumulation of moisture in pavement structures is probably the greatest cause of pavement distress” The suns ultraviolet rays harden and dry out the asphalt pavement surface. This accelerates raveling resulting in reduction of asphalt thickness in a matter of a few years. Unsealed pavement dries out, and deteriorates asphalt binder.
Pavement loses flexibility and small cracks develop. Water, chemicals, etc. penetrate the surface, and pavement deterioration rapidly progresses. Sealing asphalt pavement creates a non-porous surface which in turn prevents water penetration into the pavement. In freezing weather, open pockets of water turn to ice, which results in expansion and contraction damage to the pavement. If water soaks down to the sub-base it will often soften or erode the
base creating air space which loaded traffic on the surface cracks the pavement. Rain water then collects in these depressions and flows down through the cracks or pot holes and causes even greater damage. Many call the greater damaged areas alligatoring.
Additional Advantages to Seal Coating
Seal coating resists the highly damaging effects of gas, oil, and other road chemicals such as applications of winter salt or deicers. Seal coating restores the original rich black color of asphalt and greatly enhances overall appearance. The smooth, even surface after crack filling and sealing makes sweeping, snow removal, and maintenance easier and less costly.
Sealing costs are very little for the area it’s applied to, however has great benefits and does a lot. A quality sealing application is common sense insurance for acquiring a bituminous paved surfaced with life longevity. Preventative maintenance is more economical than expensive repairs, and replacement. The economic benefit resulting from sealing is becoming increasingly recognized. Sealing application at a cost of a few cents per square foot preserves pavement surfaces for many years. The same areas being repaired, replaced, or resurfaced with a new asphalt layer would cost many times the cost. New pavements last longer, old pavements need to be maintained property made to look and perform like new.
