HIGH ALTITUDE MOUNTAIN ROADS, A DIFFICULT LINK IN THE ROAD NETWORK. VIEWS ON PLANNING PROCEDURES AND MAINTENANCE

The safety requirements are discussed for keeping high altitude roads open throughout the year in countries with a cold climate. Different design criteria for locating such roads based on climatic conditions are examined in some detail. A survey of snow accumulation problems in the area in question is of major importance in this connection. Alignment of the road in relation to the countryside, snow drifts and directions of prevailing wind are also mentioned. The cross section profile of the road in cuts and fills is discussed, and it is emphasized that although embankments are preferred these should be relatively low since the use of guard rails will usually cause accumulation of snow. In cuts there is a general tendency for snow to accumulate and special care must be taken either to accomodate the snow beside the road in the cut or to prevent it from reaching the cut. Special solutions like elevated roads are mentioned. In conclusion the author stresses the importance of locating the road in areas of moderate winds but by-passing areas of heavy snow accumulation. /TRRL/
