Waste Aggregates in Asphalt Mixtures
2023Abstract: As part of the RILEM Technical Committee TC 279-WMR on valorisation of waste and secondary materials for roads, Task Group 3 used various waste aggregates as a replacement for natural aggregates in asphalt mixtures, namely, construction and demolition waste, recycled concrete aggregates and steel slag.

Assessing Self-healing Asphalt by the Heating of Asphalt Mixtures
2020Roads are the essential transport modal worldwide since it facilitates the movement of people and goods. Therefore, it is a concern to reduce costs and be sustainable for maintenance and rehabilitation. So self-healing has been studied. The self-healing properties of the asphalt mixtures had already been studied.

Spherical Indentation Behavior of Asphalt Mixtures
Journal of Materials in Civil Engineering, 2007The spherical indentation response of a dense bitumen macadam asphalt mixture with two different volume fractions of bitumen binder is investigated both experimentally and via an analytical model. The model for the indentation of bitumen developed by Ossa et al.

Creep Properties of Asphalt Binder, Asphalt Mastic and Asphalt Mixture
2021For designing asphalt materials resistant to permanent deformation and rutting, a low creep deformation at high temperature is the crucial performance property. Usually, creep deformation is assessed through static or cyclic compression tests at elevated temperature, both for asphalt mixtures as well as for asphalt binders. For asphalt mixtures, static

Asphalt Binder for Recycled Asphalt Mixtures
Abstract: The present chapter provides a synthesis of the research activity of RILEM TC 264-RAP Task Group 3 (Asphalt Binder for Recycled Asphalt Mixtures). The binder component, virgin and recovered from reclaimed asphalt, as well as their combination and interaction with recycling additives commonly known as rejuvenators, were addressed.

Influence of Mixture Properties on Fracture Mechanisms in Asphalt Mixtures
Road Materials and Pavement Design, 2010This paper reports a research study aimed at providing insight into key mechanisms and mixture properties that influence fracture in asphalt concrete. The experimental analysis was based on the Hot Mix Asphalt (HMA) Fracture Mechanics visco-elastic crack growth law.

Behaviour of asphalt mixtures containing reclaimed asphalt pavement and asphalt shingle
Road Materials and Pavement Design, 2014This 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

Assessment of Healing Properties of Asphalt Mixtures
2016Fatigue failure due to repeated traffic loading is a significant distress for asphalt pavements. Nevertheless, the damage associated to this phenomenon can be partially or entirely recovered during rest periods between loading repetitions, potentially resulting in a longer pavement service life.
