Surface Grinding concrete Pavements

The report outlines some of the perceptions and issues associated with Concrete roads, and asks if the process of Diamond Grinding is a viable solution to the refurbishment of worn concrete pavements. The paper outlines the process of Diamond Grinding for reconditioning structurally sound but worn concrete surfaces. Gives a description of the process and the types of machinery required. Describes the benefits relating to improved low speed skid resistance and reduced noise levels with test data recorded over a 36 month cycle on a number of test sections on 30 year old UK concrete pavements. These projects and results are supported by experience from the US including profiling with reference to a study by Wisconsin Department of Transport comparing accident rates on ground and unground surfaces over a 6 year period showing considerable reductions in accidents levels. The benefits are summarized and also give comment to further action and testing.
