Asphalt Maintenance

Good maintenance is a must if you want your driveway and parking lot to last and look like new. The sealer used is an asphalt based emulsion that is applied to the surface of the asphalt to protect and preserve the integrity of the pavement. Surfaces that remain unprotected will develop hairline cracks which will allow the elements to penetrate the surface of the driveway or parking lot. This will lead to premature failure of the asphalt. Sealcoating fills the naturally porous surface of asphalt, protecting the surface from the damaging effects of water, gasoline, oil, salt and chemicals.

Aurora Concrete will send out a trained concrete specialist, review your needs and conduct a professional site evaluation. A proposal will be drawn up and submitted promptly. Upon acceptance of our proposal, Aurora Concrete will remove your existing driveway or area to be prepared and haul it to an authorized dumping location. Aurora Concrete then will re-establish 4-6 inches of compacted base material. We then frame the area to have concrete and set up rebar throughout the entire framed area. The concrete is then poured 4 inches thick followed by a cure & seal application. Lastly, the expansion cuts are made.

Life expectancy of new concrete can be well over 20 years. Aurora Concrete warranty for all concrete work is 3 years & excludes any cracking that might occur, petroleum staining and normal wear and tear.

Concrete is considered to be the longest lasting and most durable material for driveways. Although asphalt is usually less expensive, it requires more maintenance and it’s lifespan is generally considered half of that of a concrete driveway. An asphalt driveway will also usually cost seventy five percent of a concrete driveway. A concrete driveway will also increase the value of your home more than an asphalt and give you much more curb appeal. Taking all this into consideration, concrete will give you the best return on your investment.

Asphalt Maintenance Importance

Water is one of the most damaging elements. Water when frozen expands in volume and becomes one of the strongest forces in nature. The problem with water collecting in the pores and cracks of asphalt is that the surface freezes first forcing the ice to move downward. This in turn will cause deep cracking of the asphalt down to the subgrade. This will soften and destroy the integrity of the subgrade which will lead to further deterioration of the asphalt surface. If water is continually allowed to penetrate the surface, the effect of the freeze/thaw cycle will destroy asphalt in a short amount of time. Asphalt is elastic in nature and must be this way due to the expansion and contraction caused by the heat from the sun. Asphalt being black in color, absorbs heat from the sun very efficiently. If the asphalt is left unprotected, the surface dries out and becomes brittle which will lead to cracking and alligatoring. This also will lead to premature failure of the asphalt.

Sealcoating Advantages

Some advantages to Sealcoating:

  • Resists gas and oil drippings
  • Diminishes weather damage
  • Prevents oxidation
  • Beautifies asphalt surfaces
  • Saves money

Sealcoating can be applied for PENNIES per square foot. This is in comparison to replacing an asphalt surface which can be up to 20 times that. Sealcoating extends the life of asphalt surfaces by as much as 300% and should be applied every other year. The cost of sealcoating is truly a minor expense when compared to the cost of pavement replacement.
