- As recycling continues to grow by means of utilizing waste materials in today’s world, more markets must be established for products containing recycled materials. Currently in the state of Victoria in Australia, 200,000 tonnes of waste asphalt is stockpiled annually and these stockpiles are growing. The use of reclaimed asphalt pavement in applications such as footpaths bases is an effective way of utilising them and would also significantly minimise the need for quarry based virgin materials. This paper primarily focuses on the applicability of reclaimed asphalt pavement blended with recycled crushed rock as a base material in footpaths. Reclaimed asphalt pavement (RAP) is classified as a Construction & Demolition waste material. It is obtained when asphalt is removed from rehabilitated roadways. Maximum particle sizes of 20 to 40 mm are the commonly used sized recycled RAP aggregates in construction activities. This paper discusses the results of reclaimed asphalt pavement when used in blends with recycled crushed rock for footpath base applications. The results of the laboratory tests undertaken in this research have shown overall that the incorporation of up to 50% 'reclaimed asphalt pavement' in footpath bases has 'low to minimal effect' on the physical and mechanical properties of the original material. As such, the reclaimed asphalt pavement blends with recycled crushed rock were demonstrated to satisfactorily meet the local government council requirements.
