ASPHALT ROAD SURFACES AND STUDDED WINTER TYRES

ASFALTEN OCH DUBBDAECKEN

An account of various measures taken in Sweden against excessive road wear due to studded tyres is presented. Both improved construction and maintenance methods are described. Early attempts using hot rolled asphalt with precoated chippings did not result in road surfaces which could be considered sufficiently durable. Despite improvements such as the use of coarser grades for deeper embedding and quartzite chippings with light and hard surface texture, this type of pavement has now completely gone out of use. Nowadays asphaltic concrete with coarse grade aggregate is common as paving material. The high percentage of aggregate used, however, causes difficulties at compaction works. A low voids ratio has proved to contribute to good resistance to wear. Therefore particular efforts are made at proportioning to improve the workability of the mix and to ensure that the compaction work is carefully done. Due to this improved production control a considerable (30%) increase in resistance to wear has been achieved. Four different methods of local repair for worn road surfaces are also described. /TRRL/
