Tensile and fatigue properties of bituminous mixtures between limestone and recycle concrete aggregates

The purpose of this study is to determine the tensile and fatigue properties of
bituminous mixture using limestone and recycle concrete aggregates, which were
obtained through planned laboratory processing. The objective of this work is to
understand the behaviour of bituminous mixtures, as well as investigating the
numerical relationship between the properties of aggregates on the behaviour and
performance of bituminous mixtures. The performance of a bituminous mixture is
greatly influenced by the properties of the aggregate used. Many studies have been
conducted on this subject matter globally, which is not specific to the tensile and fatigue properties of the bituminous mixture. Usual methods to determine the characteristic of the mixture use involved several tests such as the Indirect Tensile Stiffness Module Test and Beam Fatigue Test. This project also attempts to address the most suitable aggregate type to be used in bituminous mixture. Different aggregate have their own strength, physical and chemical properties that will affect
the strength and stiffness of the bitumen mixtures.
