Learn How To Sealcoat Asphalt Driveway’s and Parking Lots

This is a very crucial topic to discuss and go about which would discuss about how to sealcoat a driveway, the parking lot or any asphalt surface. It would teach everyone – how to sealcoat whether you are new to the business or a home owner who is looking for new ideas on how to do it yourself.

Sealcoating is considered a true “Barrier coat” between the asphalt surfaces and the destructive elements. The term “sealcoating” means keeping the redeeming properties of the asphalt sealed in to prolong the pace of life and also preserve its functional properties too.

Benefits of sealcoating

The primary reason to sealcoat an asphalt pavement is to protect the pavement from the deteriorating effects of the sun and water. When an asphalt pavement is exposed to the sun, water and wind, the asphalt hardens or else oxidizes. This results in the pavement to become more brittle. As a result, the pavement will crack because it is unable to bend or else flex when exposed to the traffic and temperature changes. A sealcoat combats the situation by providing a waterproof membrane which not only slows down the oxidation process but also helps the pavement to shed water, preventing it from entering the base material.

Another benefit of seal coating is an increase in the surface friction it provides. This is achieved by the additional texture the cover aggregate adds to the pavement. With time, the traffic begins to wear the find material from an asphalt pavement surface.

The Conditions Conducive to Long Lasting Sealcoats

The sealcoats are affected greatly by the weather conditions, especially during the construction. The ideal conditions are a sunny, warm day with the low humidity. The humidity and cool weather would delay the curing time and cause the seal coat to be tender for a longer period of time making it more susceptible to damage the traffic. The rain can cause major problems when seal coating. If the asphalt binder has not cured, it can become diluted and rise above the top of the cover aggregate. Thus after the water evaporates, asphalt may cover the entire surface causing tires to pick up the aggregate or track the binder across the surface. The seal coating should never be done when the shows are threatening. Asphalt to be seal coated should be in a relatively good condition. This means that there should be little, load related distress such as the alligator cracking, potholes and rutting. If these conditions exist, the driveway should not be sealed unless it is reaped first.

To Summarize – The seal coating is a good maintenance technique for pavements with the following-

  • Low to moderate transverse and longitudinal cracking.
  • A smooth surface with low friction numbers.
  • Low to moderate block cracking.
  • Low to moderate raveling.

Materials used in the sealcoat

  • Refined Coal Tar Emulsion
  • Asphalt Emulsion Sealcoating’s

The sealcoats will never compensate for the pavement defects. They are also intended as a protective coat not as a rack filter or the leveling material. Sealer is the only as good as the asphalt pavement to which it is applied. To the prevent the cracking of the bituminous pavements which are caused by the excessive voids, insufficient compaction, poor drainage, poor mix stability and low use areas.

The sealcoating should be applied with the asphalt sealer to sound pavements constructed with the popper designs and the materials that meet the climate and usage requirements of the pavement and are properly constructed over a sound and well drained base.

Thus, these are the points to be remembered while Sealcoating Asphalt Driveway’s and Parking Lots.
