Joint Sealant Failure
If you have joint sealant failure, you need to perform:
Joint/Crack Resealing
​
Uncontrolled water ingress, especially water from a pavement’s surface, contributes to multiple types of pavement distress. It can lead to spalling, base or subgrade softening, dowel bar corrosion, pavement joint blow-ups and/or materials-related distress.
For many concrete pavements, proactively sealing or filling transverse and longitudinal joints and cracks to reduce water penetration improves long-term pavement performance. In addition to limiting the entry of water, joint sealing can reduce the entry of incompressibles into the joint reservoir that exert pressure on the pavement. Performed alone, joint resealing
is a maintenance activity. However, it is also an important part of the concrete pavement preservation (CPP) toolbox.
There are two basic approaches to joint treatment (other than leaving the joint open): joint filling and joint sealing. Joint sealing involves a foam backer rod and more rigorous preparation of a sealant reservoir than filling, which often involves simply filling up a diamond saw cut joint with sealant material after minimal preparation. Joint filling may be appropriate when the reservoir is narrow and difficult to prepare, but full adhesion of the filler may be difficult to achieve, resulting in less protection from moisture penetration. In CPP projects where joints have previously been sealed, resealing them is important.

CPR Built to Last: A Progressive Concrete Pavement Preservation Strategy Improves City Streets in Minneapolis
Concrete Pavement Preservation (CPP) has long been used on deteriorated highways, but it also offers an alternative to asphalt overlays when rehabilitating city streets constructed of concrete. Techniques include: Slab stabilization, Full-depth repair (FDR), Partial-depth repair (PDR), Dowel bar retrofit (DBR), Cross-stitching longitudinal cracks or joints, Conventional diamond grinding (CDG) and Joint and crack resealing.

Quick Facts: Joint Resealing
Joint resealing protects pavement joints from water and incompressible. Uncontrolled water ingress, especially water from a pavement’s surface, can lead to spalling, base or subgrade softening, dowel bar corrosion, pavement joint blow-ups and/or materials-related distress. Performed alone, joint resealing is a maintenance activity. However, it is also an important part of the Concrete Pavement Preservation (CPP) toolbox.

CPP for City Streets: Smooth Pavements Last Longer!
Concrete pavements can achieve maximum longevity using strategic repair techniques. Today's urban streets have, in many cases, encountered 40 to 60 years of wear and tear. Concrete Pavement Preservation (CPP) is a series of engineered techniques to rehabilitate concrete pavement. It is a viable alternative to costly asphalt overlays. Basic CPP techniques include: slab stabilization, full depth repair, partial depth repair, dowel bar retrofit, cross-stitching longitudinal cracks or joints, diamond grinding, joint resealing and crack resealing.

CPR: Rebuilt to Last: Pavement rehabilitation in Jamestown, MD
U.S. Highway 281 in Jamestown, North Dakota, underwent concrete pavement rehabilitation methods to extend pavement life and minimize disruptions. Full and partial depth repair, joint resealing and diamond grinding were implemented to restore structural integrity and performance. These measures ensured cost savings, extended pavement life by 15 to 20 years, and minimized disruptions to local traffic and businesses. The project, completed two months ahead of schedule, demonstrated the benefits of targeted pavement preservation techniques.

CPR: Rebuilt to Last: Salt Lake City Concrete Pavement Restoration
In downtown Salt Lake City, Industrial Road at California Avenue required repair. The methods chosen were soil foundation stabilization, slabjacking, slab replacement, stitch-in-time crack repair, dowel bar retrofit (DBR), diamond grinding and joint resealing. The combination of using high density expansive polymers in conjunction with other concrete pavement preservation techniques including dowel bar retrofit and diamond grinding should extend the life of this pavement for approximately 15-20 years.
