Asphalt Seam Joint Repair
Prevent Surface Failure and Extend Pavement Life
The Problem
Opened or failing seam joints between asphalt mats present multiple risks, including:
- Aggregate loss along the joint line
- Exposed longitudinal joints, susceptible to water ingress
- Motorcycle safety hazards—"stuck-in-a-rut" risk
- Accelerated pothole formation and surface breakdown
The Cause
Several construction and material factors contribute to seam joint failure:
- Cold seam joints
When one mat of hot asphalt is laid against a cold mat, the bond between the two is inadequate—creating a long-term weak point. - Edge compaction issues
Asphalt cools faster at the seam, making it harder to achieve optimal compaction—leading to lower density and faster deterioration. - Unsealed joints
If no sealant is applied between the mats, the joint remains exposed to moisture and traffic loads, causing the seam to degrade and frett over time.
The Solution:
Jointmaster Seam Joint Repair
Rhino’s Jointmaster system is a proven treatment to restore and protect asphalt seam joints by:
- ✅ Sealing the joint to prevent water ingress
- ✅ Reprofiling the surface to remove rutting and fretting
- ✅ Providing a high skid resistance finish for all road users
- ✅ Re-establishing a safe, even running surface
- ✅ Reinforcing the joint to prevent further edge breakdown
- ✅ Helping the surface course last through to its design life
Jointmaster restores performance, protects structural integrity, and ensures safer, longer-lasting roads.
