As climate change accelerates, extreme weather events are becoming more frequent and severe. From flooding and freeze-thaw cycles to heat waves and hurricanes, municipalities must now prioritize infrastructure that can withstand these challenges. Traditional pavement materials and maintenance strategies often fall short in the face of such environmental stress. That’s where BioSpan’s sustainable pavement solutions—including RePlay Agricultural Oil Seal & Preservation Agent and OptiSeal Eco-friendly Penetrating Concrete Sealant—can play a transformative role.
Climate Change and Infrastructure Vulnerability
According to the National Oceanic and Atmospheric Administration (NOAA), the U.S. experienced 28 separate billion-dollar weather and climate disasters in 2023 alone. Roads and other infrastructure assets are highly susceptible to damage from extreme temperatures, flooding, and erosion. These impacts shorten infrastructure life spans and increase repair costs, placing additional strain on municipal budgets.
How BioSpan’s Solutions Strengthen Climate Resilience
BioSpan’s bio-based treatments help cities build more durable, flexible roadways that are better suited to withstand climate extremes. Here’s how:
1. Protecting Against Freeze-Thaw Damage
Moisture infiltration is a primary cause of freeze-thaw cracking in both asphalt and concrete. RePlay and OptiSeal seal surface pores and block moisture, reducing the risk of cracking, potholes, and surface breakage during winter temperature swings.
2. Resisting Heat-Induced Oxidation and Brittleness
High temperatures accelerate oxidation in asphalt, making it brittle and prone to cracking. RePlay replenishes lost oils and restores flexibility, helping asphalt roads endure prolonged heat exposure without degradation.
3. Preventing Water Damage and Erosion
Storm surges, flooding, and excessive rainfall can wash away unprotected pavement surfaces. By sealing surfaces and reducing permeability, BioSpan’s products prevent water infiltration and help maintain structural integrity in wet conditions.
4. Reducing Carbon Footprint of Maintenance Operations
Unlike conventional petroleum-based sealants, BioSpan’s bio-based formulas are low-VOC and USDA BioPreferred, reducing greenhouse gas emissions from maintenance activities and supporting municipal climate action goals.
A Municipal Success Story in Resilience Planning
A coastal municipality prone to flooding and severe storms adopted RePlay as part of a larger resilience strategy. Over three years, the city reported a 60% reduction in weather-related pavement failures, increased the average pavement life cycle by five years, and avoided $1.8 million in reactive repair costs. The city also received a state-level sustainability grant for incorporating climate-resilient practices.
Steps to Climate-Proof Your Municipal Roads
- Conduct a Climate Vulnerability Assessment – Identify pavement assets at risk from extreme weather events.
- Incorporate Resilient Materials – Choose preservation products like RePlay and OptiSeal designed to withstand temperature swings and moisture.
- Train Staff in Sustainable Application Techniques – Maximize the effectiveness of treatments with proper training.
- Track Resilience Outcomes – Measure the reduction in failures, costs, and maintenance frequency post-implementation.
Conclusion
With weather extremes becoming the norm, municipalities must shift from reactive to resilient road maintenance strategies. BioSpan’s sustainable pavement preservation products empower cities to protect infrastructure, stretch maintenance budgets, and fulfill climate adaptation goals.
