Recycled materials in road pavement infrastructure: a strategic approach to product development

In Australia, significant advances have been made in the manufacture of road making materials from industrial and demolition wastes such that industry now manufactures significant large volumes to compete in the road infrastructure market. However the adoption of such products has been restricted by the necessity to comply with traditional material specifications developed for crushed quarry materials and attempts to meet inappropriate environment contaminant requirements. This paper outlines issues associated with the general perception of the performance of recycled materials when compared against traditional virgin quarried materials. The paper details the basis upon which traditional pavement specifications were developed and presents a new approach (based upon the first principles of performance based attributes) which could facilitate the seamless acceptance of recycled materials into the road infrastructure industry. Example product developments to meet market needs in South Australia are also illustrated. (a) For the covering entry of this conference, please see ITRD abstract no. E211647.
