PROTECTING YOUR ROAD’S CRITICAL SAFETY FEATURES
When rumble strips fail, they don’t just look bad—they stop performing their life-saving function.
Rumble strips are crucial safety features that warn drivers when they’re veering off the road, but they deteriorate much faster than the main pavement.
We’ve developed specialized treatments using both JointBond (for new installations) and CRF (for aging strips) that target these vulnerable areas, extending their life and maintaining their effectiveness. Our maltene-based treatments penetrate deeply into the rumble strip surface, restoring essential maltene fractions and creating a durable, weather-resistant barrier that prevents moisture intrusion and aggregate loss.
THE SCIENCE BEHIND OUR RUMBLE STRIP PRESERVATION
Rumble strips experience accelerated deterioration compared to regular pavement because their milled or rolled impressions create additional exposed surface area and stress points.
- Our products penetrate deeply into the rumble strip surface, delivering maltene fractions that restore proper chemical balance to the asphalt
- JointBond is polymerized for durability and applied to new rumble strips before deterioration begins, while CRF includes 11% asphalt content to help heal already deteriorating surfaces
- Both treatments prevent water intrusion by sealing the porous surface and reducing permeability, protecting against freeze-thaw damage and erosion
PROVEN EFFECTIVE THROUGH RIGOROUS TESTING
Field studies conducted by the Minnesota Department of Transportation have demonstrated significant improvements in rumble strip longevity after treatment with our products. Treated sections maintained their profile depth and showed minimal aggregate loss even after multiple winter seasons.
Our testing shows that JointBond-treated new rumble strips maintain effectiveness for 3-5 years longer than untreated sections, while CRF can extend the life of already aging rumble strips by a similar timeframe, significantly improving overall safety.
WHY RUMBLE STRIPS DETERIORATE FASTER
Many road departments are surprised by how quickly their rumble strips deteriorate, often failing within just 2-3 years of installation.
This accelerated deterioration happens because:
The milling process creates additional exposed surface area that allows increased oxidation
Water collects in the indentations, leading to more freeze-thaw cycles
Snowplow blades create additional stress on the raised edges
The compaction during installation is often lower in rumble strips than in the main roadway
Traditional maintenance approaches like crack sealing can’t effectively treat rumble strips due to their unique profile. Our treatments are specifically formulated to address these challenges.
Benefits that protect roads and save lives.
- Extends rumble strip life by 3-5 years, maintaining critical safety features longer
- Preserves the tactile and audible warning function by preventing raveling and maintaining proper depth
- Reduces maintenance costs by delaying the need for expensive re-milling operations
- Improves safety by ensuring rumble strips remain effective, potentially preventing accidents
- Protects from water intrusion and brine solutions used for winter maintenance
- Maintains reflectivity of edge line striping with proper application
APPLICATION PROCESS
For New Rumble Strips: JointBond
Application: JointBond is applied to newly installed rumble strips (up to 1 year old) using a calibrated distributor truck with a precise 24-inch spray pattern.
Ready for traffic: 10-30 minutes
Uses: Preserving new rumble strips before deterioration begins
Extends rumble strip life: 3-5 years beyond normal deterioration timeline
More About JointBondFor Aging Rumble Strips: CRF
Application: CRF is sprayed in a concentrated form (90% CRF, 10% water) using a calibrated distributor truck with a 24-inch spray pattern.
Ready for traffic: 5-10 minutes for rumble strip applications
Uses: Treating rumble strips that are showing early signs of deterioration
Extends rumble strip life: 3-5 years beyond current condition
More About CRFCost-Effective PREVENTATIVE MAINTENANCE
Treating rumble strips with our maltene-based products costs a fraction of what you’d spend to re-mill deteriorated sections. The typical cost of re-milling rumble strips ranges from $0.75-$1.25 per linear foot, while our treatments cost significantly less and extend service life by years. For a typical 10-mile section of roadway, this can represent tens of thousands of dollars in savings while maintaining critical safety features.
