When it comes to protecting your asphalt pavements against deterioration. There is no greater value than a correctly applied or mixed asphalt emulsion. Sealcoating substantially reduces maintenance costs and at the same time extends the life of asphalt pavements by as much as 300%. The cost of sealcoating is truly a minor expense when compared to the cost of pavement replacement.
A few of the benefits of sealcoating:
Appearance
The dark charcoal black color of newly applied pavement sealer improves the appearance of new and old asphalt pavements. Unprotected asphalt surfaces gradually lose their rich black color due to oxidation and weathering. Sealcoating can preserve the smoothness and resilience of asphalt surfaces and help hide rough spots, small cracks, patches and some surface depressions. Pavements coated with a pavement sealer look cleaner because rainfall washes dirt and debris easily from the smooth, non-porous surface. Traffic lines become more visible.
Stops Oxidation
Actinic rays in sunlight can oxidize the Asphalt oils in pavement, causing brittleness and resulting loss of aggregates which may rob up to 50% of the original asphalt thickness in just five years. A pavement sealcoated will resist oxidative degradation and retain its value.
Reduces Costs & Increases Value
By preventing deterioration, sealcoating reduces the high costs of, for example, removal and replacement.
Resists Fuel Penetration
Resists gas, oil, salt and chemical penetration. Asphalt is a petroleum derivative, soluble in distillates such as gas, jet fuel and oil drippings. Sealcoating prevents damage from distillates and chemicals.
Prevents Water Penetration
The intrusion of moisture into asphalt pavement structure accelerates its deterioration and is strongly related to pavement distress. The sealing of well-cured asphalt prevents the seepage of moisture from snow and rain, thus preventing costly damage.
Protection
Central Paving uses only the best refined sealer that is specifically designed to protect bituminous pavements. Sealmaster, our supplier, is the leading producer of asphalt maintenance products. MasterSeal MTR is a clay-stabilized mineral filled asphalt emulsion modified with recycled, terminal blended, tire rubber for superior performance. It forms a tough, durable and flexible coating that protects asphalt pavements from the damaging elements of weather, water, salts, gas and other petro-chemicals.
Application
Asphalt sealer must be applied to structurally sound pavements by experienced applicators. Asphalt pavement should be protected by two coats; however, the quantities and rate of application must conform to manufacturer's detailed specifications. A latex rubber additive and silica sand may be added for increased traction and durability.
We usually recommend the gravity-fed application process for most properties, residential streets, driveways, small businesses, etc. The gravity-fed application is superior to the spray application, allowing a more thorough coverage and longer-lasting seal.
