Abstract

The rapid economic growth of countries has led to the construction of new structures and
infrastructures. Construction projects use up large quantities of natural resources and produce tones of
construction and demolition waste (CDW). Because of its growth, these quantities have increased in the last
few years and it has now become necessary to create a sustainable method of development in civil construction.
Therefore, utilization of recycled materials in construction projects can be the most promising solution to this
problem. The utilization of recycled materials including recycled construction aggregates (RCA) in the
pavement industry and asphalt production is particularly very promising as 90% of asphalt is made of
aggregates. However, the variability in behavior and performance of RCA used in construction projects
indicates the variability in their composition. Therefore, in spite of the awareness of the importance of using
RCA and much research being conducted, there is still a need for a deeper study of the composition of the
RCA. This paper presents the results of the statistical study and experimental work to evaluate the
characteristics of RCA as an alternative for virgin aggregate in the asphalt mixture. To this point, a series of
characterization tests were conducted RCA samples collected at different dates.
