Abstract. In addition to future raw material scarcity, environmental crises have made scientists and road authorities focus on the sustainability of asphalt pavements more than ever. With this aim, several short-term and long-term techniques and strategies have been set via carbon neutralization plans. Among these strategic plans, both asphalt recycling and Warm Mix Asphalt (WMA) play crucial...
Abstract. The priority in road construction is to reduce the energy con-sumption in the production of mineral-asphalt mixtures used for the upper layers of pavement structures. The most effective approach in this regard is production of such a mixture in the half warm technology (HWMA) with water-foamed bitumen. It is produced at a temperature 50oC to 70oC lower than that required for the...
Abstract. Together with harmful gas emissions, energy consumption is gen-erally regarded as the main issue in environmental policy. The benefits of reducing energy demand are not only related to lower environmental prob-lems (energy production and usage can be associated with air and water pol-lution, climate change, and solid waste disposal) but are also closely linked to the reduction in the...
Abstract. The elastic and viscoelastic characteristics of Warm Mix Asphalt (WMA) and traditional Hot Mix Asphalt (HMA) are closely compared in this investigation. Motivated by the need to address environmental issues, WMA, which is characterized by lower manufacturing temperatures, efficiently lowers greenhouse gas emissions and energy consumption. Furthermore, by reducing reliance on natural...
Abstract. In the past, Montmorillonite K10 (MMT K10), an acid-activated clay, was successfully used as a raw material to synthesize zeolite-like warm-mix asphalt (WMA) additive. The major objective of this research was to synthesize a foaming zeolite with bentonite as an alternative to MMT K10 and assess the physicochemical characteristics of additive through fundamental and advanced binder...
Abstract. This article evaluates the viability of cold-in-plant recycling with foamed bitumen for road rehabilitation through a case study on the ER243 road in Portugal, highlighting its alignment with European circular economy principles. The primary objective is to assess environmental benefits, construction efficiency, and the quality of this innovative recycling method as a sustainable...
