This paper is in three parts under the sub-headings "technology of grooving", "experiences hitherto" and "prospects". The aquaplaning effect and the dangers of accidents arising therefrom when travelling at high speeds on roads with a thick film of water on the surface are explained. The analogy with tyre profiles suggests enhanced safety due to grooves cut into the road surface. Details are given of cutting gear (with special emphasis on impact-free cutting using diamond saws) together with data on fields of application and output. Experience with grooving in various countries (mainly the USA, France and Germany) is judged to be positive on the basis of the proven reduction of accidents on wet roads. The main areas of application are places with poor drainage (such as bends), access roads at intersections and stretches with reverse camber. A comprehensive discussion deals with the different size and shape of grooves, the direction of grooving (longitudinal or transverse) and their respective advantages and disadvantages. A table shows a compilation of the various grooving patterns. A catalogue of unresolved questions points to the necessity of further research especially with regard to the grooving of asphalt pavements. /TRRL/
