JUSTIFICATION FOR CROSS SLOPE DESIGN CRITERIA

UNA INTERPRETAQIONE RAZIONALE DELL' INTRODUZIONE DELLE PENDENZE TRASVERSALI

The fundamental justification for design standards is that the design elements provide adequate safety limits. The criteria governing these standards are however subject to continuous change. On the basis of recent changes to existing specifications, a proposal is submitted concerning the distribution of a road's transverse profile values. Special attention is paid to questions arising from the change in cross slope. A new interpretation of the law of cross-fall variation is given and a suggestion for design criteria is made. A diagram for the determination of sideway forces on bends of different radii, transverse slopes and design speeds takes account of all 4 variables of the basic equilibrium equation. Regarding surface drainage, the basic minimum transverse slope is 2% for concrete pavements and 2.5% for bituminous pavements. A maximum transverse slope of 7% was found to be the limit for all design speeds. /TRRL/
