Rational Structural Designs for Highways in Different Climatic Zones in Sudan

Abstract

-This paper represents a pavement design guide for highways in Sudan. It is intended to provide a simple and easily applied method for determining an appropriate pavement structure for the expected design criteria. In this paper, detailed subgrade study, socio-economic study and axle loading & traffic survey have been carried out. This is meant to provide reliable and first hand data. The main findings of this paper comprise: the Sudan subgrade soil study, the guides to choose the traffic growth rates, the trucks damage factors, the guides to arrive at the correct Equivalent Standard Axles in the design period Moreover, this paper produced a design catalogue that contain 308 pavement design section to be used in Sudan and anywhere in the globe as any other international pavement design catalogue.

Linear structure taxonomy with the account of environmental polystructures impact

“…Various aspects of the impact of environmental polystructures on a linear structure are considered with respect to the stage of its life cycle. For the purpose of control of road structures with the account of environmental factors impact, regulatory documents and design guidelines adopted in different countries provide the use of systematized territorial zoning data [1][2][3][4][5]. Today, development of reliable road structures requires building regional climatic models and using special software to include the optimization techniques in the design process [6][7][8].…”
