MA4 Longitudinal Joint Sealer: The Smart Solution for Safer, Stronger Roads
The MA4 Longitudinal Joint Sealer from Cimline is an advanced, trailer-mounted sealing system designed to improve pavement life by sealing longitudinal joints before paving. Utilizing Void Reducing Asphalt Membrane (VRAM) technology, the MA4 applies hot-applied sealant beneath the future joint, helping to eliminate air and water intrusion—the top contributors to premature joint failure. For DOTs and contractors committed to building longer-lasting roads, the MA4 Longitudinal Joint Sealer is the ideal solution.
Engineered for Long-Term Pavement Performance
✔️ Precision VRAM Application – The MA4 Longitudinal Joint Sealer is built to deliver accurate, consistent applications of sealant in a straight, centered band beneath the centerline joint. This pre-treatment significantly reduces voids and permeability, ensuring your roadway is more resistant to cracking and moisture infiltration.
✔️ Self-Contained, Trailer-Mounted System – Designed for mobility and convenience, the MA4 is towable with most work trucks and features onboard material heating, automatic application control, and intuitive operator interfaces.
✔️ Fast Heat-Up and Application – With Cimline’s high-efficiency burner system, the unit reaches optimal sealant temperature quickly, allowing crews to begin work sooner and increase daily production.
Built for the Modern Road Crew
The MA4 Longitudinal Joint Sealer is more than just asphalt sealing equipment—it’s a complete tool for joint integrity and pavement protection. The automated wand and nozzle setup enables operators to apply the material without direct exposure to heat or fumes, improving both safety and precision.
✔️ Simple, joystick-controlled application system
✔️ Uniform sealant width and depth across every pass
✔️ Designed to minimize material waste and rework
Supports Asphalt Crack Sealer and Pavement Solutions
This asphalt sealer is a perfect complement to other pavement solutions such as asphalt crack sealer systems. By addressing both surface cracks and joint integrity, road crews can create more durable, water-resistant pavement systems that require fewer repairs over time.
✔️ Ideal for highways, interstates, and high-volume roads
✔️ Compatible with a wide range of hot-applied sealants
✔️ Proven to extend pavement life and improve ride quality
