PROPERTIES OF STABILIZED BLAST FURNACE SLAG ROAD BASE

Blast furnace slag, either crushed in situ or as plant crushed graded macadam, has become increasingly important as a base or sub-base on heavily trafficked roads in the Newcastle, Sydney, Wollongong region. The material predominantly used has been air-cooled slag which is considered to have self stabilizing action but at a level too weak to be classified a bound material. The investigation described in the paper examined the properties of stabilized air-cooled blast furnace slag base. Agents used to stabilize the slag were granulated slag activated either with lime or steel slag. Mixtures were evaluated which were economically feasible and which satisfied the requirements for stabilized crushed rock. Properties determined were unconfined compressive strength and resilient modulus, a property relevant to the elastic analysis of road pavements by computer methods. Alternative pavement designs using the stabilized materials were evaluated and are presented (a). The number of the covering abstract of the conference is TRIS No. 368448. (TRRL)
