Waste Aggregates in Asphalt Mixtures

2023
Abstract: 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.

Influence of binary waste mixtures on road performance of asphalt and asphalt mixture

Journal of Cleaner Production, 2021
Abstract The utilization of processed waste materials in road construction is of utmost significance from the environmental and economic viewpoints. In this paper, waste cooking oil (WCO) and ground tire rubber (GTR) were applied to modify the asphalt binder.

Creep Properties of Asphalt Binder, Asphalt Mastic and Asphalt Mixture

2021
For 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

Spherical Indentation Behavior of Asphalt Mixtures

Journal of Materials in Civil Engineering, 2007
The 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.

Assessing Self-healing Asphalt by the Heating of Asphalt Mixtures

2020
Roads 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.

Relating Asphalt Mixture Performance to Asphalt Mastic Rheology

2020
In this study, usual asphalt mixtures are tested using known and established performance testing methods. In a second step, the asphalt mastics (mastic considered as composite of asphalt binder and aggregate filler) that correspond to the asphalt mixtures are investigated with regard to their rheological properties.

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

Dynamic Modulus of Asphalt Mixtures

Transportation Research Record: Journal of the Transportation Research Board, 2015
Mix properties that deviate appreciably from the design properties during the production and construction of asphalt mixtures can lead to premature pavement distress or even failure. The objective of this study was to quantify the differences in the dynamic modulus of specimens prepared during design, production, and construction of dense-graded ...
