Construction waste in hot mix asphalt

Este 16.º encontro tivo lugar en Lisboa do 25 ao 28 de maio de 2010.[Abstract:] This paper analyzes the effect of water on the durability of hot asphalt mixtures made with recycled aggregates from construction and demolition waste. To design the asphalt mixtures Marshall tests were carried out. Indirect Tensile tests were carried out to evaluate stripping behavior. The mixtures tested were fabricated with 0%, 20%, 40% and 60% recycled aggregates. The hot asphalt mixture specimens made with different percentages of recycled aggregates from construction and demolition waste and of natural quarry aggregates showed poor stripping behaviour. This poor stripping behaviour has a negative effect on the durability of hot asphalt mixtures containing this type of recycled aggregate
