The Challenge of Asphalt Maintenance
Asphalt pavement provides a durable and safe surface for roads, driveways, and parking lots. However, it is subject to wear and tear from traffic, weather, and environmental factors. Asphalt maintenance is crucial for preventing cracks, potholes, and other types of damage that can reduce its lifespan, compromise safety, and result in costly repairs.
Traditional methods of asphalt maintenance include sealcoating, crack filling, and patching. These methods involve the use of petroleum-based products, such as coal tar and asphalt emulsion, which can have negative impacts on human health and the environment. Coal tar sealants, for example, contain toxic chemicals that can contaminate waterways and cause health problems for humans and wildlife.

Fortunately, there are eco-friendly alternatives to traditional asphalt maintenance methods that can provide comparable or superior results without harming the environment or human health.
Sealcoating is a process of applying a protective coating to the surface of asphalt pavement to prevent water, sunlight, and other elements from penetrating the surface and causing damage. Traditionally, sealcoating products are made from coal tar or asphalt emulsion. However, there are now eco-friendly options available, such as soy-based sealers, that are safer for humans and the environment.
Soy-based sealers are made from renewable resources and contain no toxic chemicals. They are easy to apply, durable, and effective at preventing weathering and oxidation that can cause cracking and fading of the pavement. Moreover, they provide a dark, shiny surface that enhances the appearance of the pavement and improves visibility for drivers and pedestrians.
Crack Filling with Bio-Based Products
Crack filling is a process of filling small cracks and voids in the pavement with a material that seals out moisture and prevents further damage. Traditional crack fillers are typically made from petroleum-based products, such as hot-applied rubberized asphalt or cold-pour crack sealants, that can emit harmful fumes and contribute to air pollution.
Bio-based products, such as sugar beet derivatives or potato starch, are now available as green alternatives to traditional crack fillers. These products are biodegradable, non-toxic, and easy to apply. They also have excellent adhesion, flexibility, and durability, and can prevent water infiltration and frost heaving that can result in potholes and other serious damage.
Patching with Recycled Materials
Patching is a process of repairing damaged or deteriorated areas of the pavement with new asphalt or other materials. Patching is often needed for larger cracks and potholes that cannot be repaired with sealcoating or crack filling.
Recycled asphalt pavement (RAP) is a sustainable and cost-effective alternative to traditional patching materials. RAP is made from crushed and screened asphalt pavement that is removed from old roads and repurposed for new construction or repairs. RAP is eco-friendly because it reduces the need for new virgin asphalt, conserves natural resources, and reduces waste. Additionally, it is durable, cost-effective, and performs well under heavy traffic and severe weather conditions.
Maintenance Practices to Extend Lifespan
Eco-friendly solutions for asphalt maintenance are not the only way to promote sustainability and reduce environmental impact. Other practices, such as regular cleaning, sweeping, and pavement markings, can help extend the lifespan of the pavement and reduce the need for maintenance and repair.
Regular cleaning and sweeping remove debris, pollutants, and other contaminants that can damage the surface of the pavement and reduce its reflectivity. Pavement markings, such as crosswalks and stop lines, enhance the visibility and safety of the pavement for drivers and pedestrians.
Moreover, implementing sustainable transportation practices, such as carpooling, biking, or walking, can reduce the volume of traffic on the pavement and increase its lifespan, while also reducing carbon emissions and promoting a healthy lifestyle.
Eco-friendly solutions for asphalt maintenance are essential for promoting sustainability, protecting human health and the environment, and ensuring the durability and safety of our paved surfaces.
Green sealcoating, bio-based crack fillers, recycled patching materials, and other sustainable practices can help extend the lifespan of asphalt pavement while reducing waste and minimizing negative impacts on air, land, and water resources. Implementing these solutions can also support environmentally responsible businesses and communities and contribute to a greener, healthier future for all.
