Evaluation of warm mix asphalt containing recycled asphalt shingles

Construction and Building Materials, 2014
Abstract Advances in asphalt materials have led to the incorporation of higher amounts of recycled asphalt materials in mixtures that can be produced at reduced temperatures. Two demonstration projects were constructed to assess the performance of mixtures that use warm mix asphalt (WMA) and recycled asphalt shingles (RAS) at reduced temperatures ...

Empirical Study of Warm Mix Asphalt Incorporating Recycled Asphalt Pavement

2021
The depletion of natural resources along with the progressive change of climate due to high heat and harmful gas emission into the atmosphere are the concerns engineers, scientists and politicians have been addressing and cooperating toward finding efficient solutions to palliate to this global issue.

High temperature characteristics of warm mix asphalt mixtures with nanoclay and chemical warm mix asphalt modified binders

Journal of Cleaner Production, 2016
Abstract With the rising price of energy and the effects of global warming, the demands for the use of warm mix asphalt (WMA) in the construction of pavements have been steadily increasing throughout the world. Due to this, many agencies have been looking forward to implementing WMA technology as a way to promote green culture in every aspect of the ...

Characterization of a Warm Mix Asphalt Containing Reclaimed Asphalt Pavements

Airfield and Highway Pavements 2015, 2015
Warm mix asphalt (WMA) technology presents a wide potential to be successfully used in road works construction projects. Although its most salient advantage is to be environmental friendly, it has technical and economic assets. Another widely mentioned advantage of WMA technology is the opportunity to be used in the production of recycled mixtures ...

Regeneration Effect of a New Bio-Based Warm-Mix Rejuvenator on Performance and Micro-Morphology of Aged Asphalt

Materials
The use of warm-mix recycling technology can reduce the mixing temperature and the secondary aging of binders in reclaimed asphalt pavement (RAP), which is one of the effective ways to recycle high-content RAP.

Fracture Toughness of Warm Mix Asphalts Containing Reclaimed Asphalt Pavement

2020
This paper deals with the fracture toughness of three different asphalt mixtures of HMA (Hot Mix Asphalt), WMA (Warm Mix Asphalt) and WMA-RAP (i.e. mixture of WMA and reclaimed asphalt pavement). Fracture tests were performed on SCB (Semi-Circular Bend) specimens to obtain the fracture properties (i.e. fracture toughness and fracture energy) of asphalt

Evaluation of Asphalt Emulsion for Use in Warm Mix Asphalt

Advanced Materials Research, 2011
Temperature grows up and climate changes year by year as result of global warming. One of the main reasons is the carbon dioxide emission. How to overcome global warming effect by means of energy conservation and carbon reduction is one of the important subjects and one of government's important administrative policies.

Performance evaluation of warm mix asphalt containing reclaimed asphalt mixtures

International Journal of Pavement Engineering, 2016
AbstractThe objective of this study is to expose the effect of a variety of variables including three reclaimed asphalt pavement (RAP) contents, two warm mix asphalt (WMA) additives and a rejuvenating agent (or lack of) on the performance of WMA containing (WMA–RAP) materials.
