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.

Properties of reclaimed asphalt pavement enriched concrete

AIP Conference Proceedings, 2021
As a consequence of increasing economic growth, the construction industry sector has higher demands on the consumption of various building materials. Concrete, one of the most important material, with the annual production over 6 billion tons is thus an essential commodity.

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 ...

Rutting Resistance of Rubberized Asphalt Concrete Pavements Containing Reclaimed Asphalt Pavement Mixtures

Journal of Materials in Civil Engineering, 2007
Improved understanding of rutting resistance of a rubberized asphalt concrete pavement that contains reclaimed asphalt pavement RAP is important to stimulating the use of rubberized asphalt mixtures. Use of RAP in the past has proved to be economical, environmentally sound, and effective in increasing the rutting resistance of asphalt mixtures ...

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 ...

Utilizing Reclaimed Asphalt Pavement in Preservation Treatments

2023
The use of reclaimed asphalt pavement (RAP) has economic and environmental impacts. This report investigates the prospective use of RAP in preservation treatments (mainly chip sealing and microsurfacing) in Illinois. A review of the current state of knowledge and practice was conducted. The economic and logistic feasibility of using RAP in preservation

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

Reclaimed Asphalt Pavement Detection and Quantity Determination

Practice Periodical on Structural Design and Construction, 2006
The use of reclaimed asphalt pavement (RAP) in asphalt mixtures provides the means to recycle the existing roadway and use that material, in a limited amount, in the construction of new pavements. This is an environmentally friendly method to recycle the existing pavement and provide a new pavement surface.

Virginia's Higher Specification for Reclaimed Asphalt Pavement

Transportation Research Record: Journal of the Transportation Research Board, 2009
In 2007 the Virginia Department of Transportation (VDOT) decided to allow higher percentages–-more than 20%–-of recycled asphalt pavement (RAP) in hot-mix asphalt with no change in binder grade. For selected VDOT resurfacing projects in 2007, six contractors produced a total of 129,277 tons of mix containing 21% to 30% RAP from seven asphalt plants in
