Samenvatting

A contactless displacement sensor has been used on a number of experimental surfaces to measure a wide range of texture depths. The texture depth as measured by the sensor is shown to give good correlation with the readings obtained by the sand patch method. Continuous monitoring of the road surface shows a large variation in texture depth along individual sections which were nominally uniformly surface dressed. Texture depth measurements made using the sensor are less variable over the length of a particular section than those by the sand patch method. (Author/publisher)
