“…However, use of secondary materials in porous surface layers of the MRN is not allowed at this moment. Research shows that this is technically feasible up to a recycled content of 15% (Frigio et al, 2014). For the evaluation of this innovation, it is calculated that 50% of the porous surface layers would consist of secondary materials.…”

“…The total fracture energy G was determined as the whole area under the load-displacement curve normalised with respect to ligament area (Biligiri et al 2012;Frigio, Pasquini, Partl, & Canestrari, 2014;Li & Marasteanu, 2010). The parameter G represents the work required to increase the fractured surface until complete failure, and is calculated as defined in Equation (7):…”

The magnitude of the binder re-activation within the reclaimed asphalt pavement (RAP) fraction is a major concern when recycled hot-mix asphalt (HMA) is produced, since it directly affects the final performance of the mix. Currently, no reliable methods to predict the RAP binder re-activation are available and the lack of such information prevents the quantification of the proper amount of virgin binder to be added to the recycled HMA.This study proposes a new method to estimate the re-activated binder amount based on the surface area (SA) of RAP aggregates. Laboratory results demonstrated the effectiveness of the SA approach in the case of RAP amounts typically used for hot-recycled HMA. Moreover, the experimental investigation suggested that revised coefficients are needed for the evaluation of the SA to account for the presence of clumps when high amounts of fine RAP aggregates are used.

“…In terms of binder selection, modified asphalt is usually used, with variations in the type and content in different regions due to varying environmental and traffic conditions [23,24]. Styrene-butadiene-styrene (SBS) modified asphalt or rubber asphalt are often used in the United States and Europe [25,26]. Hydrated lime, taking up to 1% aggregate weight and cellulose fibers, at a rate of 0.3% by total weight of the mixture [27,28], are added to reduce stripping and improve water stability [29,21].…”

Extensive studies on traditional and novel engineering materials and the increasing 8 demands by growing traffic have led to tremendous changes of the function of roads. Roads, as an 9 important part of the human living environment, have evolved from structures that were designed and built for passing vehicles, to ecological assets with significant economic importance. In addition to structural stability and durability, functions such as noise reduction, urban heat island mitigation, de-icing and exhaust gas absorption, are also expected. This study focused on state-of-the-art research on the performance, applications and challenges of six environment-friendly functional road materials, namely the permeable asphalt concrete, noise-reducing pavement materials, low heat-absorbing pavement materials, exhaust gas-decomposing pavement materials, de-icing pavement materials, and energy harvesting pavement materials. With this study, we aim to provide references to the latest relevant literatures of the design and development of environment-friendly functional pavement, and promote innovation in materials science and pavement design principles. For this purpose, this review compiled extensive knowledge in modern road construction and related disciplines, in order to promote the development of modern pavement engineering technologies.
