Rough roads not only cause a bumpy ride, but cost motorists hundreds of dollars a year. Concrete pavement preservation (CPP) basic techniques include slab stabilization, full-depth repair (FDR), partial-depth repair (PDR), dowel bar retrofits (DBR), cross-stitching longitudinal cracks or joints, and joint and crack resealing.

For roadways where tire/pavement noise is an issue, diamond ground surfaces are the solution of choice for producing quiet concrete pavements. This can be accomplished using conventional diamond grinding techniques or the Next Generation Concrete Surface (NGCS), which is the quietest non-porous concrete pavement surface available.

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.

Partial depth repair (PDR) is a vital tool in the Concrete Pavement Preservation (CPP) Toolbox. PDR is a shallow depth repair procedure used to address pavement deterioration that does not fully extend through a concrete slab. Benefits are that its fast, long-lasting, durable, smooth, cost-effective, flexible and maintains existing elements.

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.

Recently, there has been a growing interest in controlling noise at the source through the type of pavement selected. For existing highways with noise issues, diamond ground surfaces are the solution of choice for producing quiet concrete pavements. This can be accomplished using conventional diamond grinding techniques or the recently developed Next Generation Concrete Surface (NGCS).
