HC Deb 03 June 1931 vol 253 cc199-200W

asked the Minister of Transport if he has any com- parative information as to the crossfall, or superelevation, of roads at bends and curves in this country and abroad; and what steps are being taken in Great Britain to prevent skidding owing to lack of superelevation or to the use of unsuitable road surfacing materials under the varying climatic conditions of this country?


I have no comparative information relating to the crossfall or superelevation of roads at bends and curves in this country and abroad. The practice is general; but, owing to diversity of conditions, uniformity is impracticable. The advisability of superelevation has long been recognised by my Department, and a memorandum making recommendations upon the subject was issued to all local authorities in Great Britain in August of last year. The use of unsuitable surfacing materials was referred to in a circular dealing with the prevention of skidding, issued in March, 1929, and I have reason to believe that highway authorities are carrying out the recommendations of my Department on both these matters. I am sending the hon. and gallant Member copies of the Memorandum and Circular for his information.
