Carbonation is one of several ways that concrete contributes to sustainability. In typical pavement, approximately 2-3mm of carbonation may occur in the first 2-3 years whereas by year 20, the total depth of carbonation is only 5-8mm, with little additional carbonation occurring beyond year 50. The most practical way to counteract this decrease is to remove the carbonated surface with diamond grinding.

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.

This study highlights the advantages of diamond grinding in optimizing pavement performance and customer satisfaction. Diamond grinding significantly reduces road noise by providing a longitudinal texture, enhancing surface macrotexture and skid resistance. Additionally, the study touches on diamond grooving, which involves sawing discrete drainage channels into the pavement to improve safety, particularly in wet conditions. The Next Generation Concrete Surface (NGCS) is also explored, combining diamond grinding and longitudinal grooving to create a quieter, more durable pavement surface

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.

The introduction of diamond-ground surfaces on bridge decks has created some challenges, however, that can be easily overcome following a few simple tips as outlined below. Specifications for diamond grinding bridge decks generally require grinding in the longitudinal direction over the entire length of the bridge and over the full deck width, extending to within two feet of the parapets. The grinding depth required is
usually a nominal ¼ inch and continuous across all joints. Clearly, it is imperative that expansion joints and bridge components under the joints be protected from damage lest the contractor be subject to financial penalties and repair costs. To accomplish this, contractors should follow these simple tips:
