Behaviour of asphalt mixtures containing reclaimed asphalt pavement and asphalt shingle

Road Materials and Pavement Design, 2014
This paper presents the results of laboratory research on asphalt mixtures containing reclaimed asphalt pavement (RAP) and asphalt shingle, including the study of their linear viscoelastic (LVE) behaviour and fatigue characteristics. Complex modulus measurements using the tension-compression test on cylindrical specimens were conducted to determine LVE
