THIS paper gives a short account of the application of soil mechanics to road design. The principles by which wheel loads are transmitted to and resisted by the subgrade are discussed. Several methods of pavement design are reviewed, in which the necessary pavement thickness is related to the soil properties. Some experimental results are given to show the correlation of certain soil properties and their variation with moisture content. Finally brief reference is made to cement stabilisation.

THIS subject covers so much of the whole art and science of road-malting that its proper treatment in a relatively short paper is not easily decided. In the present instance an attempt has been made to give a brief review of its nature, development and scope in the hope that such information, although not novel, can form the background for a more detailed discussion.
Twenty-five years ago gunite was a new material and was chiefly used for maintenance work on concrete structures and for protecting corroded steelwork. Today the most important use of gunite to the structural engineer lies in the systematic reconditioning of weathered reinforced concrete structures, by restoring them to a state equal to new and thus avoiding reconstruction.
