Asphalt Based

Asphalt base emulsions are used to sealcoat asphalt pavements to prevent oxidation and subsequent deterioration of the asphalt. This means that the deterioration process caused by weather damage caused by wind and water will be severely curtailed.

Asphalt based sealers are also impervious to the sun's ultraviolet rays which dry out the pavement causing it to ravel and lose its flexibility. They are user friendly and have a milder less poignant odor when compared to other sealers. Higher sand loadings per gallon of sealer are used with asphalt emulsions giving them good skid resistance properties.

Contractors in the Pavement Network are experts at identifying the condition of your pavement and recommending solutions (including nothing, if that is an option) based on weather conditions, sub-base conditions, and available materials in any given region. There is no single solution that will solve asphalt problems in every region of the country. As Pavement Network members, we know that our company's experts can solve your pavement problems in our own geographical areas, and that our network partners can handle your parking lot issues in their geographical areas. You can expect the same high-quality results across the country.


After curing, the color of the finished product more closely resembles new asphalt than other sealers. Sealing your pavement with an asphalt based sealer will add extra years of and beauty when installed by trained professionals.

The Process:

  • The weather needs to be warm and dry.
  • The temperature should be 50° and rising with no rain in the forecast.
  • Nighttime temperatures should not be below 32° F.
  • The sealcoat material should be mixed in a large tank with a full sweep agitation system which will keep the mixture of coal tar sealer, sand, latex modifier and water at the proper consistency.
  • The asphalt surface must be cleaned with a combination of power brooms, power air blowers and hand tools.
  • All dirt and debris must be removed from the asphalt surface.
  • Fresh oil spots should be treated with a primer to ensure sealer adhesion.
  • Large cracks should be filled with a rubberized crack sealant.
  • The sealer is then "cut in" by hand around the edges of buildings, curbs and other non-asphalt surfaces to prevent overspray.
  • The sealer is then applied to the remainder of the parking lot in two separate coats. The second coat is applied after the first coat has dried.
  • Pavement markings can be applied as soon as the coating is dry using a heavy- duty traffic paint.
  • Traffic can be introduced to the lot in 12 - 24 hours based on climate conditions.
