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: Rebuilt to Last: White Bear Lake Highway 61 CPR repairs last 22 years
US Highway 61 travels through White Bear Lake, MN. In 1987, it required full depth repair and partial depth repair, diamond grinding, re-saw and seal with silicone in the transverse joints and hot pour sealant in the longitudinal joints. The Concrete Pavement Restoration (CPR) methods performed more than two decades ago are still in good condition, lasting longer than originally predicted.

CPR: Rebuilt to Last: John Kilpatrick Turnpike, Oklahoma City, OK, Interstate 40 near Yukon to I-35
In 2005, the Oklahoma Turnpike Authority (OTA) identified the need for significant road repairs on the John Kilpatrick Turnpike. Full depth repair, dowel bar retrofit (DBR), diamond grinding and joint resealing methods of repair were selected to address the deterioration. It is predicted that it will be 15 to 20 years before any additional major work will need to be completed.

CPP: Rebuilt to Last: Diamond Grinding and Patching Restore U.S. 67 in Arkansas
Concrete pavements last 40+ years; treatment with CPP restores rideability. A 120-mile-long stretch of U.S. 67 connects North Little Rock, AK to Walnut Ridge, AK. Concrete pavement preservation (CPP) was deemed appropriate for rehabilitating the highway using diamond grinding. After patching and grinding, there was about an 80% improvement in smoothness.

CPR: Rebuilt to Last: Concrete Pavement Restoration on State Highway in South Dakota
The city of Watertown, South Dakota, chose diamond grinding and dowel bar retrofit (DBR) for its US 212 project to enhance ride quality and skid resistance. DBR was implemented to restore load transfer across joints. The result was a smooth surface that has remained in good condition for more eight years.

CPR: Rebuilt to Last: A progressive concrete pavement preservation strategy improves city streets in Minneapolis
City streets in Minneapolis benefited from the implementation of concrete pavement preservation (CPP) techniques. The strategy focused on rehabilitating structurally sound residential streets using methods such as diamond grinding, dowel bar retrofit (DBR), full depth repair (FDR), partial depth repair (PDR), cross/slot stitching, joint resealing, and crack resealing. This approach was chosen for its sustainability and cost-effectiveness, enhancing road safety and extending pavement lifespan by up to 25 years.

CPR: Rebuilt to Last: Concrete patching and resealing maintenance for major city roads in Glen Ellyn, IL
City blocks in Glen Ellyn, Illinois, were rehabilitated using diamond grinding and full depth repair (FDR). Diamond grinding enhanced surface smoothness, and FDR addressed deeper structural issues, leading to improved urban road quality. These methods provided a cost-effective, long-term solution for preserving the roads, with an expected lifespan extension of up to 10 years.
