Pavement Maintenance: Sealcoating

• Sealcoating is designed to protect asphalt pavements from the damaging effects of the environment, including moisture and ultraviolet oxidation.  Protecting pavement with sealcoating has basically the same effect as using sun block on your skin or varnish on wood-it slows the destructive effects of our extreme southwestern climate.  Sealcoating also minimizes raveling (the loss of aggregate) and fills minor voids in the surface.  Other benefits include creating a uniform color and appearance for all paved asphalt surfaces and increasing the visibility of curbing.  Sealoating and re-striping of parking spaces and crosswalks improves traffic flow and enhances public safety.

• We use a coal tar based material that provides superior protection from sun and weather damage.  For additional application longevity, we recommend applying two coats of pavement sealer.  Since the initial surface preparation and edge work make up the majority of the cost of the first application , adding a second layer is economical and increases overall durability.

• To reduce long-term maintenance expenses, industry experts recommend that pavement be sealcoated every two to three years, depending on traffic and overall condition.  Pavements that exhibit extensive cracking, base failure, or severe surface raveling will not significantly benefit from sealcoating.  Also, sealcoat tends not to adhere well to areas saturated with oil, so such areas must be treated with an oil spot primer to aid adhesion.  Sealer can be applied by either squeegee or spray methods. is recommended for smooth pavement, whereas rough, porous surfaces are better serviced by the squeegee method with its thicker application.  Normal curing time is 24 hours for moderate temperature and humidity condtions
