ABSTRACT
As a result of reconstruction of existing buildings and pavements, the amount of demolition
materials is increasing every year. At the same time approval of additional facilities for waste
disposal or treatment are become more difficult to obtain. Furthermore increasing restrictive
environmental regulations have made waste disposal more difficult and expensive while the
available natural aggregate for pavement construction in some countries decreases. Many
scientific studies have been trying to provide us the information and methods to keep the
environmental clean and mention the natural balance of life and reuse of construction and
demolition materials in highway construction which has great benefits. The recycling of
waste and byproduct materials represents the main role in these studies. This study aims to
characterize the recycled aggregates produced from crushed concrete and bricks and to
examine properties of asphalt concrete produced with each recycled aggregates as a full or
partial replacement of the natural aggregates. The results will be used to find suitable
applications for each aggregate as pavement materials.
