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.

Effects of Reclaimed Asphalt Pavement on Hot-mix Asphalt

Advances in Civil Engineering Materials, 2014
Abstract This study examined the effects of reclaimed asphalt pavement (RAP) on the structural properties and performance of hot-mix asphalt (HMA) and the rheological properties of asphalt binder in the laboratory. As a first step, dynamic modulus (|E*|) and indirect tensile strength (ITS) tests were conducted on a set of HMA samples ...

Evaluation of Asphalt Mixes Containing Reclaimed Asphalt Pavement

Applied Mechanics and Materials, 2012
The use of Reclaimed Asphalt Pavement (RAP) has been enormously increased from the last two decades. In fact using RAP in pavement construction has now become common practice in many countries. Using RAP not only economical and environmental friendly but also preserve the natural resources and similar or even better in structural performance than ...

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 ...

Pavement Performance of Asphalt Surface Course Containing Reclaimed Asphalt Pavement (RAP)

Journal of Testing and Evaluation, 2012
Abstract Reclaimed asphalt pavement (RAP) provides many advantages. The performance of a provincial road with an asphalt surface course containing RAP in Zhejiang, China was evaluated. The surface course was prepared by central plant hot mix recycling and virgin asphalt concrete. An AC-13 was chosen as gradation design in all mixes.

Effect of reclaimed asphalt pavement on performance of rubberised asphalt mixtures

Proceedings of the Institution of Civil Engineers - Construction Materials, 2020
The utilisation of crumb rubber (CR) and reclaimed asphalt pavement (RAP) has proven to be an economical, environmentally sound and effective way of increasing the performance of asphalt mixtures. The objective of this study was to evaluate the use of CR in high RAP content asphalt mixtures.

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
