“…It should be taken into account when considering recycled shingles in road construction works to keep shingles of different sources assorted for proper design and implementations. The range of AC content varied from 14.6 to 36.7% in the RAS from different sources used in that study which deemed considerably influential [33]. Asphalt binder from tear-off shingles is considered stiffer than the binder from pre-consumer shingles due to aging and environmental exposure issue [34].…”

“…Fiberglass shingles are of an asphalt cement rate of about 15% less than that contained in the organic shingles, which in-turns makes fiberglass shingles cheaper and preferable over organic ones [30]. The content of asphalt cement in Recycled asphalt shingles ranges from 19% to 31% [33]. The aim of utilizing asphalt shingles in road construction is to reduce amount of virgin binder [34].…”

“…into asphalt mixtures at varying rates of 5% to 10% displayed that as the rate of RAS increased, tensile strength declined [24,30,33] and resistance of thermal cracking also dropped [34]. HMA is believed to exhibit more durability when RAS is used [34].…”

Research objective: analysis of waste disposal issues in the mining and mineral processing industry of the Russian Federation. Research methodology: economic and environmental challenges concerned with mining and mineral processing waste in dumps and tailings were analysed. Results: an option is proposed to dispose of the waste rock generated by the mining and processing industry by using it for construction of railways and motor roads. This technology makes it possible to avoid construction of quarries and temporary settlements for their development along the road route, which will decrease the environmental impact and significantly reduce the time and cost of road construction. Conclusions: The proposed technology helps to achieve a significant economic effect (no costs for transporting materials from remote areas of the country), reduce the adverse environmental impact of mining operations and, in the long term, prevent dump formation.

“…A softer virgin asphalt binder was required to restore the low temperature properties of the mixture to those of the control mixture (Arnold, 2014). The fatigue cracking resistance of RAS modified HMA was studied by Cascione et al (2015) and Wu et al (2016). Cascione et al (2015) conducted four-point bending beam testing on several asphalt mixtures and found that both RAS and non-RAS mixtures performed well with respect to fatigue performance, and, in fact, the RAS modified asphalt mixtures performed slightly better than the control mix (Cascione et al, 2015).…”

The inclusion of recycled asphalt shingles (RAS) in asphalt mixtures has become increasingly common; however, the underlying design principles vary significantly by agency. The primary objectives of this study included: (1) evaluating the ‘binder availability’ concept for RAS mixtures through a carefully designed laboratory experiment; (2) demonstrating a balanced mixture performance testing approach for the design of RAS mixtures; and (3) evaluating the field data of RAS mixtures placed in the Midwest region of the U.S. Three asphalt mixture designs with RAS contents of 0.0, 2.5 and 5.0%, which were designed to have nearly identical volumetric characteristics, were investigated. The binder availability was determined to be approximately 100% in the two RAS mixtures considered. In addition, Hamburg wheel tracking and disk-shaped compact tension tests were conducted to evaluate the high- and low-temperature mixture performance. As expected, the addition of RAS significantly improved the rutting resistance. DC(T) test results demonstrated that a soft base binder effectively permitted the design of thermal-crack-resistant RAS mixtures. Field investigations indicated that the performance of pavement surfaces containing RAS was similar to that of surfaces containing only reclaimed asphalt pavement or virgin materials. This study also highlights a performance-engineered mix design approach, which is currently being adopted by several agencies in the Midwest (e.g. Illinois Tollway, Missouri DOT, etc.) and can provide mix designers a reliable approach for designing innovative asphalt mixtures with higher recycling levels and a modern, heterogeneous composition. Furthermore, the proposed approach may prove to be a simpler, more mixture-centric alternative to the primary method suggested in AASHTO PP78-17, which recommends arbitrary VMA bumping plus binder extraction, recovery, and advanced binder testing.
