Spalled Joints & Cracks
If you have spalled joints and cracks, you need to perform:
Partial Depth Patch Repairs
Partial depth repair (PDR) is a shallow depth repair procedure used to address pavement deterioration that does not fully extend through a concrete slab. This method is used to repair spalling and fraying of concrete slab edges at joints and cracks as well as localized scaling. Spalling, which can occur on both jointed and continuously reinforced pavements, reduces pavement serviceability and can become hazardous to highway users. This type of deterioration can be caused by a number of factors including late sawing, poor joint design, inadequate joint/crack maintenance and material durability issues such as Alkali-Silica Reactivity (ASR). Once initiated, spalls tend to grow under repeated thermal stresses and traffic loadings.
The purpose of PDR is to repair surface defects, reestablish joint reservoirs and restore localized areas of deterioration. PDR replaces unsound concrete to restore rideability and discourages further deterioration. Further, PDR is an excellent preventative maintenance technique as it is proven to last more than 20 years when properly constructed using quality materials and workmanship.

Long-Lived Concrete Pavement: TH 210 in Minn. Achieves a 69-Year Service Life—With More Years to Come
There are a few key takeaways. First is that pre-emptive maintenance, often referred to as pavement preservation, is necessary to maximize the life of a pavement. Second is that smooth pavements stay smooth longer, so implementing techniques like dowel bar retrofit (DBR), diamond grinding and joint resealing early in the pavement’s life will reduce dynamic loads and greatly increase the amount of time a pavement remains serviceable at a high level for minimum cost.

CPR: Rebuilt to Last: US Highway 153, Mosinee, Wisconsin
On U.S. Highway 153 in Mosinee, Wisconsin, partial depth repair (PDR) and full depth repair (FDR) were utilized to restore structural integrity and ride quality. PDR addressed surface defects while FDR tackled deeper issues. These repairs have extended the pavement's lifespan and reduced maintenance costs. The project, completed in 2½ months, highlights the advantages of PDR for quickly addressing shallow problems at joints and extending pavement service life without the need for extensive overlays or replacements.

Concrete Pavement Preservation (CPP) Built To Last
In 2020, Oklahoma's concrete pavements were due to begin a maintenance cycle, and by the end of that year, concrete pavement preservation (CPP) consisting of selected panel replacements, dowel bar retrofit (DBR) and diamond grinding had been completed on portions of the Cimarron, Bailey and Indian Nation Turnpikes. CPP allows for seven times the length of roadway repaired for every dollar spent.

CPR: Rebuilt to last: US Route 33, Appalachian Corridor H, Barbour, Upshur and Randolph Counties, WV
A 21-year-old 4.20-mile section of U.S. Route 33 in Upshur County, WV, exhibited distressed areas in need of repair. Full depth repair, partial depth repair, and diamond grinding techniques were chosen for the project. Compared to more traditional methods, the WVDOH feels that the application of these techniques is an effective combination of treatments to treat a significant portion of this corridor and provide long-term performance at a relatively low cost.

CPR: Rebuilt to Last: Highway 21 repairs Newark, NJ
When the New Jersey Department of Transportation (NJDOT) set out to repair Highway 21 on the north side of Newark, they sought a cost-effective solution that would result in a safe, smooth ride. Recognizing that the existing pavement was structurally sound, NJDOT removed the asphalt overlay and performed diamond grinding on the underlying concrete pavement. The techniques used to complete the project included asphalt milling, cat basin reconstruction, slab stabilization, pre-cast panel replacement, partial depth repair, joint resealing and diamond grinding for the final ride and surface texture.

CPR: Rebuilt to Last: Roosevelt Roads Naval Base runway repairs, Ceiba, Puerto Rico
In 2001, the U.S. Navy sought to repair the 11,000-foot runway that served the Navy's Atlantic air fleet. The project employed partial depth repair, full depth repair, sawing, stripping, and joint resealing. The result for the naval base was a quality runway that will provide safe, economical service for many years into the future.
