abstract = {The widespread use of plastics in modern society, coupled with the challenges of recycling certain types, has driven the exploration of their application in asphalt mixtures to promote circular economy principles and mitigate environmental impact. This laboratory study explores the feasibility of using polyolefin waste as a partial aggregate replacement in warm mix asphalt (WMA) using the dry process without additional treatment. The research began by determining the optimum bitumen content through a mixture design based on the moisture damage resistance test. This same test was then used to identify the optimum polyolefin waste content from seven different WMA mixtures, introducing the coarse-sized polymer as an aggregate substitute, at mass-based replacement rates (0.5%, 1.0%, 1.5%, 5.0% and 10.0%) with volume control, and employing two distinct incorporation methods. Subsequently, the control and polyolefin-modified mixtures were evaluated regarding volumetric and mechanical properties, including abrasion resistance, stiffness, thermal susceptibility, resistance to permanent deformation and fatigue life. The findings demonstrate that incorporating polyolefin waste at a substitution level of 0.5% enhances both abrasion and moisture damage resistance, effectively repurposing a challenging waste material. However, despite these benefits, it also presents some limitations in permanent deformation resistance compared to the control mixture.},

abstract = {In recent decades, sustainable practices in pavement construction have been studied to promote circular economy principles and protect the environment. This research seeks to determine the potential benefits of using three different industrial waste materials in formulating warm mix asphalt (WMA). WMA mixes were prepared using ground granulated blast furnace slag (GGBFS) from steel production and biomass fly ash (FA) from the paper industry as virgin filler replacement, and an industrial waste rich in lignin biopolymer (LB) from the hardboard industry as a partial substitute for binder. The study analyzed their volumetric and mechanical properties, including moisture damage resistance, resilient modulus, fatigue resistance, permanent deformation, and abrasion resistance, which were compared with those of a control WMA mix (without any waste). The findings provide insights into an important gap in the literature on the use of GGBFS and LB in WMA. GGBFS-2 mix (75 % GGBFS) exhibited the best fatigue performance but the highest axial deformation and rut depth. LB-1 mix (5 % LB) performed slightly worse than the control WMA mix in all tests.},

abstract = {The incorporation of recycled concrete aggregates (RCA) from construction and demolition waste (CDW) in hot-mix asphalt (HMA) could be a way to promote sustainable construction. This paper describes a laboratory study on the use of RCA in HMA for base courses in road pavements. HMA involving RCA in percentages of 0%, 5%, 10%, 20% and 30% were evaluated. To improve the moisture damage resistance of HMA made with RCA, the mixtures were cured in the oven for 4 h at a mixing temperature of 170°C, before compaction. The results indicated that the mixes made with RCA and cured for 4 h in the oven loosely fulfil the Spanish moisture damage specifications. The results also indicated that the Marshall Stability and the moisture damage resistance are substantially improved by curing the mixture in the oven. The mixtures also exhibited an adequate resistance to permanent deformation. The results from this study were highly encouraging, although HMA with RCA requires further investigation.},
