Modified Asphalt Mixtures Incorporating Pulverized Recycled Rubber and Recycled Asphalt Pavement

Civil Engineering Journal
In the search to achieve eco-friendly techniques that ensure significant improvements in the properties of hot mix asphalt (HMA), recycled materials are being considered with greater application, coming from the pavement itself and also from artificial elements such as rubber. In this sense, the objective was to study the behavior of the mechanical and

Experimental Investigation of Temperature Distribution and Evolution in Hot Recycled Asphalt Mixtures with Different Reclaimed Asphalt Pavement Contents

Recycling
Temperature homogeneity assumes a crucial role in the manufacture of asphalt mixtures due to its impact on mechanical formation and mixing homogeneity. The existence of reclaimed asphalt pavement (RAP) exacerbates its impact on temperature inhomogeneity.

Performance and Aging Characteristics of Asphalt Binders and Asphalt Mixtures Incorporating High Recycled Asphalt Pavement and a Recycling Agent

Transportation Research Record: Journal of the Transportation Research Board
The increased use of recycled asphalt pavements (RAP) is motivated by the need to enhance resource efficiency and reduce environmental effects. Asphalt recycling agents may also be added to high RAP mixtures to mitigate the impact of stiff, brittle RAP binder, leading to enhanced performance.
