Roads are subjected to daily traffic, environmental stress and aging. Without an effective maintenance plan, pavement can deteriorate quickly, resulting in repair costs and reduced service life.
For contractors and municipalities, effective pavement preservation isn’t just about maintenance; it’s about extending performance, reducing costs and protecting roadways. With the right asphalt sealer, road surfaces can be preserved, protected and enhanced across a wide range of conditions, from low-traffic municipal roads to busy highway shoulders.

Types of Asphalt Sealers for Roads
Choosing the best asphalt sealer for roads can vary by project requirements and pavement condition.
Asphalt emulsion sealers are commonly used in routine pavement preservation programs. They help protect against oxidation, moisture intrusion and surface wear while maintaining flexibility as pavement expands and contracts.
Surface sealers, including advanced hard-residue emulsions, are designed to restore and protect asphalt surfaces while improving durability and appearance. These technologies are widely used in pavement preservation programs due to their ease of application and long-term performance benefits.
Polymer-modified sealers are designed for higher-performance applications. By incorporating advanced additives, these sealers improve durability, enhance resistance to traffic wear and extend service life—making them ideal for roads with higher traffic demands.
Road sealcoating is a form of preventive maintenance, protecting pavement before it fails. Sealcoating roads is widely recognized as the most cost-effective and effective strategy for extending pavement life.
Considerations for Selecting an Asphalt-Based Sealer for Roads
Traffic Volume
Roads that experience higher traffic require more durable surface treatments to withstand turning, braking and continuous wear.
Climate and Exposure
Factors such as freeze-thaw cycles, UV exposure and moisture all impact pavement performance and should be considered when selecting products.
Maintenance Planning
Some sealers are applied more frequently, while others are designed to extend maintenance cycles. The best approach depends on your budget and long-term planning goals.
Application and Scheduling
Cure times, weather conditions and crew availability all influence how efficiently a project can be completed.
Common Sealcoating Mistakes to Avoid
Even if the right product is chosen, inadequate planning or application can result in premature failure.
Common mistakes include:
- Selecting based solely on price
- Mismatching the sealer with the road type
- Skipping surface preparation
- Ignoring weather conditions and timing
- Failing to create a consistent maintenance plan
- Improper Mixing (Adding too much water)
It’s important to note that delaying maintenance can cause damage to worsen, leading to more expensive repairs. Cracks and surface damage must be repaired before sealing; without proper preparation, the sealer won’t perform as expected.

Premium Surface Treatments for Pavement Preservation
Liquid Road is a polymer-modified, fiber-reinforced surface treatment designed to extend pavement life and improve durability. When mixed with aggregate, it creates a slip-resistant surface that holds up under traffic while maintaining a consistent texture.
It is the go-to for contractors, municipalities and Departments of Transportation (DOTs) as part of their pavement preservation program on roads, streets and other asphalt surfaces where long-term performance is a top priority. Liquid Road extends pavement service life while improving surface condition, maintaining durability and delivering the darkest black finish while remaining cost-effective for budgets.
For ease at the jobsite, Liquid Road is also available in a ready-to-use formulation. Liquid Road Ultra is factory-blended with sand, water and additives, eliminating the need for on-site mixing. This keeps your crews moving which improves consistency and efficiency to keep your project moving.
Liquid Road is implemented nationwide in various municipal and contractor-led maintenance programs, including projects in Indiana, Michigan, North Carolina, Virginia, Ohio and Arizona. These programs focus on maximizing budgets while extending pavement life to ensure consistent performance across road networks.

Surface Sealers for Routine Maintenance
OptiPave is a hard-residue surface sealer that provides superior toughness and extended service life. It replenishes the asphalt binder otherwise known as the “glue” that holds the pavement together, which is lost over time due to weathering, traffic and aging.
This sealer is designed to maintain surface condition and extend pavement life with ideal use on residential streets, county roads, highway shoulders and other paved surfaces. Optipave can also be applied as a topcoat over slurry and chip seals.
OptiPave provides a consistent, even-textured surface with no loose aggregate, while also improving the overall appearance of the pavement. Its deep black finish enhances pavement markings and helps improve visibility.
The single-coat application allows for fast installation with minimal disruption to traffic, making it a practical option for routine maintenance programs.
OptiPave is a leading solution in municipal maintenance programs across the nation, including in New Mexico, where numerous self-performing agencies have successfully incorporated it into their pavement preservation programs. OptiPave stands out as the best choice for road maintenance because it hits the key goals of pavement preservation: protect early, extend life and reduce costs.
Additional Sealer Options for Applications
SealMaster offers additional sealer options that allow contractors and municipalities to adjust based on their project needs.
MasterSeal is a clay-stabilized asphalt emulsion pavement sealer designed for protecting and preserving all types of asphalt. MasterSeal will more than double the life of your asphalt with a regular sealcoating schedule of 2-3 years.
PMM (Polymer Modified MasterSeal) is the gold standard of pavement sealer. This polymer-modified, mineral-filled asphalt emulsion is engineered for superior adhesion, flexibility and durability, delivering consistent performance from batch to batch. PMM provides excellent sprayability and a deep, uniform black finish while offering higher solids and faster drying times for improved efficiency on the jobsite.
MasterSeal and PMM are also available in ready-to-use Ultra formulations, allowing crews to reduce mixing time, improve consistency and increase efficiency on the jobsite.
