Transportation Research Record: Journal of the Transportation Research Board, 2022
With the increased use of recycled materials and various additives, the performance of asphalt mixes, especially their cracking resistance, has become a primary concern. Researchers have developed performance test methods and parameters to simulate field performance in the laboratory.

Journal of Materials in Civil Engineering, 2017
AbstractAs the price of liquid asphalt continuously climbs, methods are being sought to decrease material costs without compromising material or pavement performance while having a positive influence on sustainability. One potential method is the use of recycled materials, such as recycled asphalt shingles (RAS) and reclaimed asphalt pavements (RAP ...

Industrial & Engineering Chemistry Research, 1997
Several asphalts were fractionated using supercritical pentane. These fractions were analyzed by gel permeation chromatography and high-performance liquid chromatography, and their viscosities were measured. The properties of these fractions vary not only among the fractions of a given asphalt but also for the same fraction produced from different ...

Asphalt Binder for Recycled Asphalt Mixtures
Abstract: The present chapter provides a synthesis of the research activity of RILEM TC 264-RAP Task Group 3 (Asphalt Binder for Recycled Asphalt Mixtures). The binder component, virgin and recovered from reclaimed asphalt, as well as their combination and interaction with recycling additives commonly known as rejuvenators, were addressed.

Cold Recycling of Reclaimed Asphalt Pavements
2018Pavement 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.

Innovative Infrastructure Solutions, 2017
In Quebec, for more than 20 years, cold in-place recycling (CIR) and full-depth reclamation (FDR) have been reliable rehabilitation techniques; restoring pavement condition at an affordable cost with a lower footprint on the environment. Experience reveals that CIR and FDR interventions effectively address the issues of reflective cracking and respect ...

Evaluation of Recycled Asphalt Shingles in Hot Mix Asphalt
Transportation and Development Institute Congress 2011, 2011The objective of this study was to evaluate the performance of asphalt mixtures containing different dosages of recycled asphalt shingles (RAS) using the dynamic modulus (|E*|) test with a universal testing machine and rutting test with the asphalt pavement analyzer (APA). In this study, 5% and 10% RAS were used in the Superpave mixtures.
