Uses of Soil-Vegetation Survey Information in Road Construction1

Abstract

Abstract

Engineers constructing roads in upland areas derive much information from soil-vegetation survey data. Soil series characterized as to their behavior for road construction enable the engineer to lay out roads that pass through the areas of better soils and avoid the difficult ones. Vegetation data guide the engineer in routing his road to mature timber stands. They show him what problems will be involved in clearing rights-of-way. Much more work must be done in testing laboratories to determine bearing ratios, optimum moisture percentages, swell percentages, and other characteristics for soil series. However, field approximations of these data can be made, and these are all valuble aids to the engineer.
