CAPITAL COST IMPLICATIONS OF ALTERNATIVE PAVEMENT WIDTHS

In 1978 a review was made of design options for a 6 km section of the Arthur highway between Sorell and Forcett. The review considered three alternative designs in combination with a number of pavement and shoulder widths. These were analysed to determine their cost and capacity. The cost of construction is not always linearly related to formation width. The comparison of cost to service volume provides a ready means of relating design variables, horizontal and vertical alignment, shoulder and pavement width together with fixed parameters such as traffic volumes, composition, and speed to the cost of construction. This may be achieved by means of an index or graphically. Within a given formation width it is more economical to increase pavement width rather than shoulder width provided that a minimum shoulder width of 1.2 M is provided. The determination of the optimum combination of alignment pavement and shoulder width is derived from a comparison of suitable options with the capacity required. (TRRL)
