Severely Cracked Slabs
If you have severely cracked slabs, you need to perform:
​
Full-Depth Repairs
Full-depth repair is the removal and replacement of full slab thickness sections of deteriorated pavement. Length can vary based on conditions present. A common minimum patch size is four to six feet long and a full lane width wide. This type of repair can be completed on both jointed and continuously reinforced concrete pavement. On jointed pavement, the transverse construction joints at the patch ends are typically doweled and/or tied to restore load transfer across the joints. Additionally, on longer patch sections, dowel bar assemblies are placed at intervals to coincide with the existing transverse joint pattern present. On continuously reinforced concrete, the reinforcing steel pattern of the existing pavement is removed and replaced with new steel within the repair section. The transverse repair boundaries are first sawed and jackhammered to expose approximately two feet (typical) of the existing steel to facilitate the tying of the new reinforcement bars to the steel pattern in the existing pavement.

Diamond Grinding: A Safe, Sustainable, Quiet and Cost-Effective Solution to Better Roadways
This white paper presents several case studies demonstrating the benefits of diamond grinding for maintaining and improving roadway conditions in Arkansas, California, Kentucky, and Phoenix. The importance of managing slurry/concrete grinding residue (CGR) for environmental compliance is also emphasized throughout the various case studies.

Concrete Repair Best Practices
Concrete pavement restoration (CPR) techniques have gained greater national significance as DOT agencies attempt to further extend infrastructure service lives prior to required major rehabilitation or reconstruction. This report consolidates best practice case studies for six CPR techniques: cross stitching, dowel bar retrofit, diamond grinding, full depth repair, partial depth repair and slab stabilization.
