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.

The Utah Department of Transportation (UDOT) carefully considered a variety of options to repair the 20-year-old concrete pavement on I-84 in Box Elder, UT. The methods selected included dowel bar retrofit (DBR), diamond grinding, full depth repair, partial depth repair, slab jacking and joint resealing. This newly rehabilitated highway will provide a safe, smooth and durable surface for many years to come.

The National Highway Route 60/MT200 is a four-lane highway located in Great Falls, MT that connects several small towns in central and eastern areas of the state. The project to make the roadway smooth and safe for drivers involved repairing approximately 12 lane mines of nine-inch Portland Cement Concrete (PCC). Methods included dowel bar retrofit, full depth repair, partial depth repair, diamond grinding and resealing. The project proved to be a cost-effective solution.

In 2013, the Utah Department of Transportation (UDOT) began concrete rehabilitation on a 15-mile stretch of Interstate 15 in Ogden, UT. Concrete Pavement Preservation (CPP) methods selected for the project included partial and full panel patching, slab jacking, resealing, dowel bar retrofit (DBR) and diamond grinding. UDOT provided a safe, smooth ride while reducing costs.

The surface of the Route 63 highway had become rough after carrying 40-plus years of significant passenger and commercial traffic. The Arkansas Highway Transportation Department (AHTD) opted to use patching and diamond grinding as well as joint sawing and joint resealing. The roadway now boasts a safer riding surface with a nearly 56% improvement in smoothness.

While Concrete Pavement Preservation (CPP) techniques include slab stabilization, full depth repair, partial depth repair, dowel bar retrofit, cross stitching longitudinal cracks/joints, diamond grinding, joint resealing and crack resealing, the most common CPP technique used in Kentucky is diamond grinding. Kentucky demonstrated five years of improved IRI through diamond grinding and saved over $1 billion using pavement management systems (PMS).
