Limtstone (calcareous aeolinite) stabilised with bitumen has been used as a pavement material in Western Australia for some time. Traditionally, the bitumen has been added in an emulsified form and mixed in situ by graders. More recently, the mixing has been done off-site in a fixed plant. Variations in the quality of limestone used have led to the addition of varying bitumen contents. However, the selection of the bitumen content appropriate to the field on guideway and off-guideway braking operations. The compromise may be accomplished by use of either different naturally occurring deposits of suitable gravel become scarce, an investigation was initiated to rationalise the selection of a bitumen content for stabilising limestones of varying quality. This paper presents the progress made along these lines and an approach which is believed to be environmental impact.
