“…These tools allow to practical investigation many variables associated in manufacturing the RTR-MBs. The tools can also precisely control the temperature, continuously monitor the viscosity measurements in real-time, keep the rubber uniformly distributed within the blend by creating a convective like flow, and consume as little as 10-15 g of material (Celauro et al 2012, Lo Presti et al 2014, Lo Presti & Airey 2013. (Lo Presti et al 2014) …”

This study wants to provide fundamental understanding of prolonged storage time on asphalt rubber binder properties by performing an investigation on the variation of conventional properties, rheology and morphology of four asphalt rubbers maintained at 180C in low shear for different digestion/storage times up to 48 hours. The analysed asphalt rubbers were manufactured by combining two different asphalt binder grades, pen 35/50 and pen 50/70, with both cryogenic and ambient crumb rubber. Results have shown that keeping asphalt rubber agitated at the above mentioned processing conditions, up to 48 hours, is significantly detrimental when an ambient crumb rubber is used, while it seems not to negatively affect the asphalt rubber produced with cryogenic rubber crumbs. Instead, no remarkable change is recorded when asphalt rubbers are produced with the same rubber type and by changing the base asphalt binders, namely pen 35/50 and pen 50/70.

“…Recently, crumb rubber recycled from used tires has been used in the modification of asphalt and has improved asphalt mixture performance (Neto et al, 2006;Thives et al, 2013;Lo Presti, 2013; Lo Presti and Airey, 2013). This use is typically carried out by applying crumb rubber from tire grindings to modify the asphalt used in asphalt mixtures or to replace part of the aggregates in asphalt mixtures (Peralta et al, 2010;Lo Presti et al, 2014). The other components of recycled tires (fibers and metals) are not used in the asphalt mixtures and are discarded.…”

The use of crumb rubber in the modification of asphalt has occurred because of the problems related to disposal of scrap tires. However, the use of scrap tires in asphalt pavements, known as asphalt rubber pavements, can minimize environmental impacts and maximize conservation of natural resources. The textile fibers from recycled tires are typically disposed of in landfills or used in energetic valorization, but similar to other fibers, they can be used as a valuable resource in the reinforcement of engineering materials such as asphalt mixtures. Thus, this work aims at studying the use of textile fibers recycled from ground tires in the reinforcement of conventional asphalt mixtures. The application of textile fibers from ground tires was evaluated through laboratory tests on specimens extracted from slabs produced in the laboratory. Indirect tensile tests were performed on a series of nine asphalt mixtures with different fiber and asphalt contents and compared with a conventional mixture. The results obtained from a 50/70 pen asphalt were used to define three asphalt mixture configurations to be used with 35/50 pen asphalt. The results indicate that the textile fibers recycled from used tires can be a valuable resource in the reinforcement of asphalt mixtures.
