“…Alwaeli ( 2016 ) pointed out that Poland was the first European country to introduce an ELT management system, which was initiated by tire manufacturers and importers. Clar-Garcia et al ( 2016 ) studied the European regulations devoted to the reduction of tire noise depending on the age structure of ELTs. Xie et al ( 2016 ) concluded that tire manufacturers took measures to modify the structure of tires to avoid uneven wear.…”

Environmental and social awareness are the key elements of the sustainable tire industry. End-of-life tire (ELT) waste flow is an important environmental problem worldwide since it produces severe air, water, and soil pollution issues. Significant advancements have been made in ELT management in the last few years. As a result, ELTs should not only be regarded as waste but also as a source of environmentally friendly materials. Besides, sound ELT management has vital importance for circular economy and sustainable development. Over the last decade, ELT management has attracted many researchers and practitioners. Unfortunately, a comprehensive review of the ELT management area is still missing. This study presents the first critical review of the whole ELT management area. It aims to present an extensive content analysis overview of state-of-the-art research, provide its critical analysis, highlight major gaps, and propose the most significant research directions. A total of 151 peer-reviewed studies published in the journals between 2010–2020 are collected, analyzed, categorized, and critically reviewed. This review study redounds comprehensive insights, a valuable source of references, and major opportunities for researchers and practitioners interested in not only ELT material flow but also the whole waste management area.

“…While addressing the effective robustness of the results obtained through pass-by methods, Clar-Garcia et al [51] noted that CPB measurements can be strongly influenced by external conditions such as the age or roughness of the pavement. For this reason, a slight change in the experimental setup may lead to significantly altered and non-reproducible results.…”

“…They noted that CPB measures lack repeatability, even when the procedure is conducted by the same team and test vehicle. Despite the introduction of correction coefficients for well-known environmental variables such as temperature or humidity, other factors that are difficult to describe through weighting coefficients, such as wind speed, tire wear over time, and the effects of the surrounding urban soundscape, can alter the results of CPB measurements [51,52].…”

Noise associated with road infrastructure is a prominent problem in environmental acoustics, and its implications with respect to human health are well documented. Objective and repeatable methodologies are necessary for testing the efficacy of sustainable noise mitigation methods such as low noise emission pavement. The Controlled Pass-By (CPB) method is used to measure the sound generated by passing vehicles. Despite its popularity, the applicability of CPB is compromised in urban contexts, as its results depend on test site conditions, and slight changes in the experimental setup can compromise repeatability. Moreover, physical conditions, reduced space, and urban elements risk confine its use to only experimental road sites. In addition, vehicle speed represents a relevant factor that further contributes to the method’s inherent instability. The present paper aims to extend the applicable range of this method and to provide more reliable results by proposing an adjusted CPB method. Furthermore, CPB metrics such as LAmax do not consider the travelling speed of the vehicle under investigation. Our proposed method can yield an alternative metric that takes into account the duration of the noise event. A hypothetical urban case is investigated, and a signal processing pipeline is developed to properly characterize the resulting data. Speed cushions, manhole covers, and other spurious effects not related to the pass-by sound emissions of ordinary vehicles are pinpointed as well.
