Safe and sure handling of a vehicle depends on how well the tires grip the road. Experience has shown that diamond grooving a pavement’s surface is a very effective method to increase traction, reduce hydroplaning and minimize splash and spray as well as provide a more effective braking surface.

Grooved runways are a win-win situation. Not only does diamond grooving make runways safer, but it’s also a time and cost-effective solution for rehabilitating older runways. Because it can be targeted specifically to the areas that need additional traction, diamond grooving does not require massive shut-downs that can elevate costs. The FAA recommendations for runway diamond grooving are used on most major runways in the United States.

Full-depth repair (FDR) is a vital tool in the concrete pavement preservation toolbox. Joint deterioration (i.e., cracking, breaking or spalling at edges, where edges are defined by longitudinal or transverse joints) is a common form of distress requiring full-depth repair. Other distresses requiring FDR can include blowups, corner breaks, isolated concrete durability issues or severe random cracking.

Research conducted by NDOR demonstrates that slurry application on roadway shoulders is safe. When diamond grinding concrete highways, water used to cool cutting blades combines with hardened cement paste and aggregate particulates, generating a byproduct known as concrete grinding residue (CGR), or slurry.

When diamond grinding concrete highways, water used to cool cutting blades combines with hardened cement paste and aggregate particulates, generating a byproduct known as concrete grinding residue (CGR), or slurry. Years of research demonstrate that proper application on roadway shoulders is safe. CGR slurry with 13 percent to 28 percent ECCE (up to 40 dry tons/acre) had no negative effects when deposited on the roadside.

Pavement base and subgrade repairs are a vital tool in the Concrete Pavement Preservation (CPP) Toolbox. Subgrade repair comes in several forms, including slab stabilization (aka undersealing and subsealing), slab jacking, and medium and deep injection grouting. The best time to perform subsurface restoration is soon after loss of support is detected.
