ROAD SCABBLING

STRASSENFRAESEN

The significance of the speedy regeneration of damaged road surfaces is growing. Road scabbling makes it possible to remove parts of the surface in order to apply a new layer and also to even out bumps or re-roughen smooth carriageways to improve skid resistance without having to apply a new surfacing course. The range of road scabbling work has increased noticeably in recent years and should continue to do so. There are some cutters which operate cold and others which work on warmed surfaces pre-heated to around 150 deg C. Both methods have advantages and disadvantages. Various makes of scabblers are being introduced which have capacities of 2000 to 20000 square metres per day for a cutting depth of 3 cm and an average cutting speed of 3 - 6 metres per minute. The higher running costs of the warm scabblers is more than offset by a better performance and the longer life of the hard metal cutters. With warm milling the excavated material remains usable and good scabbled surfaces are achieved. Large cutting tools linked directly to a loading plant are already in existence. The amount of dust and smoke generated by warm milling is minimal. /TRRL/
