“…With the presence of fibres, the formation and development of microcracks can be restricted through the fibre bridging action resulting in a longer fatigue life. Moreover, the crumb rubber attached the RTPF may act as an energy absorber during the fatigue loading if an effective bond arises between rubber particles and concrete matrix [63].…”

The utilization of recycled tyre polymer fibre (RTPF) into concrete production is feasible to promote sustainable development and mitigate environmental pollution of global landfilled waste tyres. This paper for the first time presents an experimental study on flexural fatigue behaviour of concrete reinforced with mixed RTPF considering different fibre dosages (i.e., 1.2, 2.4, 4.8 and 9.6 kg/m 3). Results indicate that with the presence of RTPF, the flexural strength of concrete was increased by 3.6-9.6%. The fatigue life of all mixtures followed the two-parameter Weibull distribution and can be accurately predicted using the developed double-logarithm fatigue equations. Concrete reinforced with 4.8 kg/m 3 of RTPF presented the longest fatigue life under different failure probabilities. RTPF and polypropylene fibre (PPF) reinforced concrete exhibited similar fatigue failure mechanisms. 0.2-0.4% Vf of RTPF could substitute around 0.1% Vf of PPF in concrete considering overall static, dynamic and fatigue performance.

“…However, one of the best solutions to reduce noise in the surroundings, thus preventing health effects, is to use pavements with improved acoustic features. Gap-graded bituminous mixtures with crumb rubber (CR) may be an effective way to reduce noise, as well as the End-Of-Life (EOL) tires disposal on landfills [16,17], which is a significant environmental problem because tires are highly durable and non-biodegradable [18]. CR can be incorporated into asphalt mixes by means of the dry or the wet processes.…”

Pavements are made up of several layers with different mechanical and functional characteristics. The correct design of the surface layer of a road may lead to pavements with better characteristics regarding ride quality and safety, but also pavements that may be used as a measure against noise. The use of low-noise pavements may be an effective measure to reduce the generation of acoustic pollution by road traffic. This work aims to assess some functional characteristics of a rehabilitated urban street, after two months in service conditions. The pavement was fabricated with a gap-graded bituminous mixture type Stone Mastic Asphalt (SMA) with crumb rubber (CR) from end-of-life (EOL) tires. This work studies the acoustic performance of the pavement, as well as other surface characteristics such as the macrotexture depth (MPD) and the unevenness (IRI), establishing the relationship between them and the tire/road noise at different frequencies. Finally, the main vertical acceleration frequencies of the pavement/vehicle system at 50 km/h were also assessed and related to the pavement unevenness and conservation. According to the results, this mixture might be used as a noise mitigation measure within the Action Plans of some urban areas with problems related to noise. The macrotexture depth of the mixture contributes to its acoustic performance at low frequencies; however, its acoustic performance cannot be totally explained from a macrotexture point of view.

“…Rubber from recycled tires are a source of sustainable new material that are also used to create environmentally friendly and low-cost composites [ 10 ]. In civil engineering materials, researchers have used rubber from recycled tires in mortars [ 5 ]; cement concrete [ 2 , 4 , 11 ]; geogrids in granular soils [ 12 ]; aggregates [ 13 , 14 ]; soil reinforcement [ 15 ]; composite membranes [ 16 , 17 ]; and asphalt [ 18 , 19 , 20 ]. The use of metal fiber waste from tires is less explored; however, researchers have investigated the effect of fiber waste from tires in the mechanical, fire resistance, and acoustic properties of concrete [ 21 , 22 , 23 , 24 , 25 , 26 ].…”

Evaluation of Asphalt Mixtures Containing Metallic Fibers from Recycled Tires to Promote Crack-Healing

et al. 2020

This paper reports part of an international research project with the long-term aim of developing more sustainable asphalt mixture with crack-healing properties by the addition of recycled metallic waste from industrial sources. Specifically, this article presents an evaluation of the physical, thermophysical, and mechanical properties of asphalt mixtures with metallic fiber obtained from recycled tires for crack-healing purposes. Detailed results on the crack-healing of asphalt mixtures will be reported in a second article. Results showed a small reduction on the bulk density and increase in the air voids content was quantified with increasing fiber contents. The experimental results showed that mixing and compaction was more difficult for higher fiber contents due to less space for the bitumen to freely flow and fill the voids of the mixtures. Computed tomography (CT) results allowed to identify clustering and orientation of the fibers. The samples were electrically conductive, and the electrical resistivity decreased with the increase of the fiber content. Fiber content had a direct effect on the indirect tensile stiffness modulus (ITSM) and strength (ITS) that decreased with increasing temperature for mixtures and with increase in fiber content. However, the indirect tensile strength ratio (ITSR) was within acceptable limits. In short, results indicate that fibers from recycled tires have a potential for use within asphalt mixtures to promote crack-healing.
