Pavement Preservation Services:
Chip Seal (Surface Treatment)
A chip seal is a preventive maintenance treatment used to treat raveling, oxidized pavements and loss of friction. Chips seals can also be applied to seal top-down fatigue cracks less than 8mm in order to keep water from seeping into and weakening the road base. Once the chip seal emulsion is sprayed onto the roadway, chip seal aggregate, which can vary in size, is spread over the emulsion. This is followed by rolling and compaction. The aggregate helps to provide increased durability and resistance to moisture and heavy traffic, which can cause fatigue cracking and raveling. Chip seals can also be applied during the process of upgrading gravel roads to paved roads.
Micro Surfacing
Conventional micro surfacing is a preventive maintenance and pavement repair treatment with standard 3% polymer modification of the asphalt base. It is used to treat oxidation and raveling, and can be applied to fill ruts. Conventional micro surfacing applications also result in increased surface friction, making road surfaces safer for drivers. This treatment extends the service life of roads 5-7 years. Additionally, it can be applied as the top layer/final course in a cape seal application.
Cape Seal
Cape Seal is a pavement preservation treatment that combines a chip seal with a slurry seal or micro surfacing to create a smooth, durable, and long-lasting surface. The chip seal provides a strong, waterproof base with excellent skid resistance, while the slurry or micro surfacing layer locks in the aggregate, eliminates loose stones, and improves ride quality. This process enhances pavement durability, reduces maintenance costs, extends roadway life, and provides a safer, more aesthetically pleasing surface with minimal traffic disruption.
Slurry Seal
Slurry Seal is a protective asphalt treatment designed to restore surface texture, seal minor cracks, and extend the life of aging pavements. It consists of a mixture of asphalt emulsion, fine aggregates, water, and portland cement, which is applied as a slurry and cures to form a durable, skid-resistant surface. This cost-effective treatment protects against oxidation and moisture damage, improves road safety, and helps delay expensive repairs or resurfacing.
Fog Seal
A light application of emulsion sprayed on the roadway surface, providing a quick return-to-traffic time and improved aggregate retention with trackless properties. Typical uses are over new chip seals, rejuvenating scrub seals and existing pavement surfaces — resulting in increased service life of 2-4 years.
Tack Coat / Bond Coat
A trackless bond or tack coat is an application of emulsion or asphalt binder with trackless properties that is sprayed onto the roadway surface immediately prior to a paving operation. The trackless properties ensure the bonding material stays where it is needed, resisting being picked up by tires, paving equipment and haul trucks and tracked across the job site.
Granular Sealing
Granular Sealing is a single application of either a specially formulated asphalt emulsion or a low-viscosity asphalt cutback. Their primary functions are to penetrate quickly into the granular surface and bind the material together, to partially waterproof the granular surface to prevent water erosion.
Pavement Preservation
Pavement preservation plays a crucial role in extending the lifespan and maintaining the functionality of roads and other paved surfaces. It involves a proactive approach to prevent or mitigate the effects of aging, weathering, and traffic-related wear and tear. By implementing regular pavement preservation services, our company aims to minimize the need for costly and extensive repairs or reconstruction.
Key benefits of pavement preservation include:
Cost Savings: Investing in timely pavement preservation is a cost-effective strategy compared to the expenses associated with major repairs or reconstruction. It helps prevent deterioration, reducing the overall life cycle costs of the pavement.
Asset Protection: Well-maintained pavements protect the significant financial investments made in construction projects. Preservation measures, such as chip sealing and micro surfacing, act as barriers against water infiltration and harmful UV rays, safeguarding the structural integrity of the pavement.
Safety Enhancement: Preserving pavement ensures a smoother, skid-resistant surface, contributing to safer driving conditions. Regular maintenance reduces the likelihood of accidents caused by potholes, cracks, or uneven surfaces.
Environmental Impact: Pavement preservation minimizes the environmental footprint associated with road construction and rehabilitation. It promotes sustainability by prolonging the life of existing infrastructure and reducing the need for raw materials.
Community Convenience: Well-maintained roads enhance the overall quality of life for residents and commuters. By addressing minor issues promptly, pavement preservation services contribute to smoother traffic flow and minimize disruptions caused by construction-related closures.
Proactive Approach: Pavement preservation is a proactive measure that identifies and addresses potential problems before they escalate. This approach maximizes the return on investment by extending the service life of pavements and minimizing the need for reactive and costly interventions.
In summary, our company’s pavement preservation services are integral to ensuring the longevity, safety, and cost-effectiveness of paved surfaces. By adopting a proactive approach to maintenance, we contribute to the overall sustainability and functionality of infrastructure, benefiting both our clients and the communities they serve.
