Physical and Mechanical Properties of Reclaimed Asphalt Pavement (RAP) Incorporated into Unbound Pavement Layers

Applied Sciences, 2022
Against the backdrop of global warming and depletion of natural resources, new techniques and alternative materials need to be explored and integrated into road construction. Reclaimed Asphalt Pavement (RAP) is one of the waste materials that can be reused in new road projects if its behavior is better understood.

Hybrid deep learning model for predicting failure properties of asphalt binder from fracture surface images

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 16, Page 2248-2268, 30 June 2025.
Abstract Cracking impacts asphalt concrete durability primarily due to cohesive asphalt binder failures. The poker chip test has recently been introduced to better characterize the cracking potential of asphalt binders by fracturing a specimen in a realistic stress state to a thin binder film.

Interfacial bonding mechanisms and physicochemical evolution at the reclaimed asphalt pavement aggregates-cement interface

Frontiers in Built Environment
The performance of cement-stabilized reclaimed asphalt pavement (CSRAP) mixtures is closely related to the structural evolution and bonding behavior of the interfacial transition zone (ITZ).

Light Absorbing Particles Deposited to Snow Cover Across the Upper Colorado River Basin, Colorado, 2013–2016: Interannual Variations From Multiple Natural and Anthropogenic Sources

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 2, 28 January 2025.
Abstract Atmospheric particulate matter (PM) as light‐absorbing particles (LAPs) deposited to snow cover can result in early onset and rapid snow melting, challenging management of downstream water resources. We identified LAPs in 38 snow samples (water years 2013–2016) from the mountainous Upper Colorado River basin by comparing among laboratory ...

Uses of Reclaimed Asphalt Pavement (RAP) in Flexible Pavements

International Journal for Research in Applied Science and Engineering Technology
One of the most frequently used waste materials is reclaimed asphalt pavement (RAP). The use of RAP can help reduce the cost of a project and ensure that the project is eco-friendly. Therefore, the aim of this study is to give a detailed description of the production of RAP to ensure that the rehabilitation and maintenance of pavements as well as the ...

Gridlock: Infrastructure and Jurisdiction in Eastern Navajo Agency

Antipode, Volume 57, Issue 1, Page 169-192, January 2025.
Abstract This article examines how settler legal orders in Eastern Navajo Agency produce conditions of impasse that defer investments in life sustaining infrastructures, like roads. Focusing on the conjuncture of infrastructural decay and jurisdictional friction amid an oil and gas boom, I elaborate a concept of “gridlock” as a deadly effect of settler

Impact of reclaimed asphalt pavement (RAP) on low-temperature properties of asphalt concrete

Roads and Bridges - Drogi i Mosty, 2019
Hot mix recycling is a practice which enables reusing materials from old asphalt pavements. Current Polish regulations allow usage of RAP only for binder and base courses, and its amount is limited. Asphalt mixtures with RAP material have to fulfil requirements stated for typical asphalt mixtures.

Gradient boosting decision trees to study laboratory and field performance in pavement management

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 1, Page 3-32, 2 January 2025.
Abstract Inconsistencies between performance data from laboratory‐prepared and field samples have been widely reported. These inconsistencies often result in inaccurate condition prediction, which leads to inefficient maintenance planning. Traditional pavement management systems (PMS) do not have the appropriate means (e.g., mechanistic solutions ...

Valorization of Reclaimed Asphalt Pavement (RAP) from the Highway Materials Circularity

International Journal of Pavement Research and Technology
Abstract The increasing demand for natural resources in highway construction presents significant environmental and economic challenges. A key issue is the disposal of reclaimed asphalt pavement (RAP), which is often discarded in landfills, despite its potential for reuse in new asphalt mixtures.
