Load Distribution in Prestressed Concrete Bridge Systems

The purpose of this paper is to give a description of the practical application of different methods of soil stabilisation in fine materials for the construction of road bases and the foundations of structures. The sequence of the sections follows the order of the operations in the job from the untouched site to the finished pavement. The observations made herein and the conclusions drawn from them are based on an intensive study of the working of a million cubic yards of excavation, a hundred and twenty thousand square yards of formation and fifty thousand cubic yards of soil stabilised with additives, the last two without the importation of hardcore or aggregates of any kind. The geographical situation of the site is immaterial, but the geological description of materials dealt with is most important. These descriptions could apply over large areas, since many alluvial strata, such as windblown and desert sands now allowed to go to waste, come within the particle sizes which may be stabilised by these methods.
