| Description | The paper describes studies accomplishes at the University of Nottingham with two secondary aggregates used in road construction: furnace bottom ash (FBA) and slate waste. Both materials are described in terms of the industrial processes, which generate them, availability, location and present use in the construction industry. In addition to conventional characterization and classification tests for aggregate materials, repeated load triaxial tests were performed. For the FBA, the materials degradation under compaction, its self-cementation and permanent deformation characteristics were also assessed. The FBA fails to meet the British DOT specification for primary aggregates for sub-base layers. However, the results indicate that it has adequate properties for use in lightly trafficked roads. Although the slate waste meets the Dot specification and laboratory testing indicates good resilient modulus characteristics, its present utilization is currently limited. The benefits, disadvantages and feasibility of both materials for road construction are discussed. |
