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.

Relating Asphalt Mixture Performance to Asphalt Mastic Rheology
2020In 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, 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

Expansion inhibition of steel slag in asphalt mixture by a surface water isolation structure
International Journal on Road Materials and Pavement Design, 2020To inhibit volume expansion of steel slag and improve pavement performance of steel slag asphalt mixture, a surface water isolation structure was proposed by employing three surface treatment approaches. Properties of the surface modified steel slag were

Dynamic Modulus of Asphalt Mixtures
Transportation Research Record: Journal of the Transportation Research Board, 2015Mix 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 ...
