Cracks in asphalt are more than surface-level flaws—they are entry points for water, debris, and weather damage that can quickly compromise pavement integrity. Routing and hot crack sealing is a proven maintenance process designed to extend the life of asphalt surfaces by addressing cracks before they become costly repairs. At Gopher State Sealcoat, this method is a core part of our pavement preservation services, helping property owners protect their investments with long-lasting results.
What Is Routing in Asphalt Crack Repair?
Routing is the process of mechanically widening and cleaning existing cracks to create a uniform reservoir. This step is critical because it removes loose debris and ensures the crack sealant can properly bond with the asphalt. Without routing, sealants may sit unevenly on the surface and fail prematurely. Proper routing allows the sealant to penetrate deeply, improving flexibility and adhesion as temperatures change.
Understanding Hot Crack Sealing
Hot crack sealing involves filling routed cracks with a heated, rubberized sealant specifically designed for asphalt movement. The material is applied at high temperatures so it flows into the crack and bonds tightly with the surrounding pavement. Once cooled, it remains flexible, expanding and contracting with seasonal temperature shifts while maintaining a watertight seal. This process is widely recognized as one of the most effective ways to prevent crack growth and pavement deterioration.
Why Routing Improves Sealant Performance
Routing creates the ideal crack geometry for sealant application. By forming clean, consistent edges, the sealant can anchor itself securely, reducing the risk of pull-out or separation. This step also ensures that the sealant thickness is adequate to handle traffic loads and thermal expansion. When routing is skipped, even high-quality sealants may fail early, leading to repeated maintenance and higher long-term costs.
Key Benefits of Routing & Hot Crack Sealing
This maintenance approach offers a balance between cost-efficiency and durability, making it a smart choice for parking lots, driveways, and roadways. The process slows oxidation, prevents water infiltration, and preserves the structural base of the asphalt. For property owners in Minnesota’s demanding climate, Hot Crack Sealing MN services are especially valuable due to frequent freeze-thaw cycles that accelerate pavement damage.
- Extends pavement lifespan by reducing crack expansion
- Prevents water penetration and base erosion
- Improves surface appearance and safety
- Reduces long-term repair and replacement costs
- Enhances performance in extreme temperature changes
When Should Crack Sealing Be Performed?
Timing is critical for effective crack sealing. Ideally, routing and sealing should be done when cracks are still manageable and before they interconnect into larger failures. Spring and fall are often optimal seasons, as moderate temperatures allow sealants to cure properly. Regular inspections help identify early-stage cracking, ensuring maintenance is proactive rather than reactive.
The Role of Professional Application
While crack sealing may seem straightforward, professional equipment and expertise make a significant difference. Trained technicians understand proper routing depth, sealant temperature, and application techniques that ensure long-term performance. At Gopher State Sealcoat, we follow industry best practices to deliver consistent, high-quality results tailored to each pavement’s condition and usage.
Long-Term Value for Property Owners
Investing in routing and hot crack sealing is a strategic decision that protects asphalt assets and minimizes disruption. Compared to major resurfacing or reconstruction, this maintenance method delivers a high return on investment by delaying larger repairs. For commercial properties, well-maintained pavement also enhances curb appeal and reduces liability risks associated with uneven or damaged surfaces. Choosing Hot Crack Sealing MN services helps ensure pavement remains functional and visually appealing year after year.
