Abstract [en]

Grinding of cement concrete pavements to reduce unevenness and noise is common since a long time. Grinding is then made with wheels equipped with diamond blades rotating in the vertical plane. This creates narrow vertical/longitudinal grooves in the pavement. It is not applied to asphalt pavements.

In this paper an alternative type of grinding is studied. In this case plates with diamond heads rotate in the same plane as the pavement, thus shaving off peaks in the asphalt pavement texture. The result is a pavement with a "negative texture". This type of (horizontal) grinding has been applied in Sweden in various ways to a stone mastic asphalt pavement as well as to a porous asphalt pavement. Also an Australian study is reviewed.

This paper describes the technique and its effect on tire/road noise, tire/road rolling resistance and skid resistance. It is found that noise is reduced by 0-3 dB by the horizontal grinding on both pavement types considered, and that rolling resistance is reduced by 7-14 %. This applies to the first year of service but the effects are reduced with time relatively fast. However, depending on the circumstances and the cost of grinding the effect may be technically and economically justified.
