This paper presents the findings of various research programs and laboratory tests on the effects of slow-setting cementitious stabilisation binders on marginal pavement materials. It presents the VicRoads evaluation of the slow-setting binder developed by Blue Circle Southern Cement, Alkali-Activated Slag (commercially known as "Roadment"). The information presented includes research work performed by a wide range of organisations, including private industry, state road authorities and local government. An overview of the need for and the development of these slow-setting binders will also be discussed. The conclusion summarises the adverse effects of delays to compaction on materials stabilised with GP and GB cements and the advantage that slow-setting binders have when extended working time is desired.
