Blending and diffusion of reclaimed asphalt pavement and virgin asphalt binders

Road Materials and Pavement Design, 2014
An experimental study to understand the properties of reclaimed asphalt pavement (RAP), virgin binder and their respective blends was conducted. It was found that the current AASHTO (American Association of State Highway and Transportation Officials) M 323 specification recommendation to use one-grade softer performance graded asphalt at>15% RAP ...

Successful Use of Reclaimed Asphalt Pavement in Asphalt Mixtures

open access: yes, 2021
Over 99 percent of reclaimed asphalt pavement (RAP) is put back to use, with most of it in asphalt pavements. Using RAP in asphalt mixtures can provide initial cost savings by replacing a portion of the aggregate and virgin asphalt binder in the asphalt ...

Asphalt Pavements with High Reclaimed Asphalt Pavement Content

Transportation Research Record: Journal of the Transportation Research Board, 2014
Today's sustainability-driven systems require a product or process to be environmentally beneficial as well as cost-effective. This study used life-cycle cost analysis (LCCA) and life-cycle assessment (LCA) to consider the economic and environmental feasibility of using a high content of reclaimed asphalt pavement (RAP) in asphalt mixtures.

Effect of Fractionation of Reclaimed Asphalt Pavement on Properties of Superpave Mixtures With Reclaimed Asphalt Pavement

Advances in Civil Engineering Materials, 2015
Abstract While the necessity for cost effective and sustainable replacements for virgin paving mixtures is becoming more and more evident in recent years, particularly with asphalt binder and aggregate economics and the obligations for using greener alternatives, contradictory performance results of high percentages of reclaimed asphalt ...

Sustainable use of reclaimed asphalt pavement (RAP) in pavement applications—a review

Environmental Science and Pollution Research, 2023
The purpose of this review is to examine the innovative usage of Reclaimed Asphalt Pavement (RAP) in flexible pavement applications. RAP is elucidated as isolated pavement earthly materials consisting of asphalt and aggregates. When the existing/old asphalt is removed for reconstruction, and resurfacing, these materials are generated. Now, it is highly

Cold Recycling of Reclaimed Asphalt Pavements

2018
Pavement engineers have in front of them multiple challenges linked to addressing issues related to social development and society’s expanding needs. One of the most substantial of these issues is perhaps how to effectively rehabilitate and/or maintain the existing road network while preserving and sustaining limited natural resources.
