“…En cuanto a la fluidez, según Swathi et al (2021), la adición del 5 % de escoria de acero permite obtener un flujo de 3,30 cm, lo cual demuestra la capacidad de la mezcla asfáltica para resistir el asentamiento gradual y su deformación. Osuolale et al (2023) destacan que la adición del 15 % de polvo de escoria mejora la fluidez de la mezcla, medida mediante el método de Marshall, y aumenta el rendimiento del hormigón asfáltico. De acuerdo con Anupama et al (2023), una adición del 50 % de escoria mejora la resistencia a la tracción, a la humedad y la fluidez.…”

El desarrollo de la infraestructura de transporte desempeña un papel fundamental en el fomento de actividades turísticas al mejorar la accesibilidad a diversos destinos. La calidad de las carreteras pavimentadas, en particular, influye en el flujo del comercio y el turismo. La investigación se centró en evaluar la influencia de la adición de escoria metalúrgica (EM) en las propiedades mecánicas de los pavimentos flexibles. Se utilizó una muestra de 60 briquetas que se sometieron a pruebas utilizando el método Marshall con diferentes niveles de adición de EM; 5 %, 8 %, 12 % y 15 %. Los resultados revelaron que la combinación de un 4,5 % de contenido de asfalto (CA) y un 12 % EM demostró ser adecuada en términos de estabilidad, alcanzando un valor de 1540,3 kg, así como un flujo promedio de 2,73 cm. En consecuencia, se concluye que la inclusión de EM mejora las propiedades mecánicas de la capa asfáltica, lo que sugiere que este material podría ser utilizado en el diseño de mezclas para pavimentación vial. Se recomienda que el porcentaje de EM a utilizar se encuentre en el rango del 5 % al 10 % para mantener un equilibrio adecuado entre estabilidad y flujo en la mezcla.

“…Among these roads, asphalt concrete pavement, known for its advantages of low noise, high comfort, and easy construction, is the primary road surface material (Yang et al, 2022;Gong et al, 2023;Lv et al, 2023;Xie et al, 2023). Especially in the construction of expressways in China, the proportion of asphalt concrete pavement exceeds 90% (Cui et al, 2021;Li et al, 2022b;Osuolale et al, 2023). Typically, asphalt concrete is composed of asphalt, aggregates, and mineral fillers (Taherkhani and Vahabi Kamsari, 2020;Jia et al, 2022).…”

“…The findings indicate that FA and GP greatly increased the stiffness of steel slag asphalt concrete, resulting in enhanced anti-rutting performance, but slightly reduced the water damage resistance of asphalt concrete. Osuolale et al (2023) used bamboo leaf ash (BLA) as filler in asphalt mixture and investigated the road performance of asphalt concrete. They found that in addition to enhancing asphalt concrete's volume stability, rutting resistance, and low-temperature cracking resistance, BLA filler can also strengthen the adhesion between asphalt mortar and aggregate, but the fatigue life and anti-skid performance of asphalt concrete were reduced.…”

As a kind of solid waste, using Prestressed High-Strength Concrete Pile Waste Concrete (PPWC) as the replacement for limestone filler in asphalt concrete can not only reduce the accumulation of PPWC and increase its utilization but also avoid the increased road construction costs and environmental degradation associated with limestone mining. This study aims to investigate the effect of using PPWC filler to replace limestone filler on the road performance of asphalt concrete. Firstly, PPWC was ground into filler particles with a diameter less than 0.075 mm. The particle characteristics such as surface morphology, particle size distribution and chemical composition of PPWC filler and limestone filler were compared. Then, PPWC filler was used to replace limestone filler with different volume fractions to prepare asphalt concrete, and the water damage resistance, high-temperature rutting resistance, low-temperature crack resistance, fatigue resistance and adhesion performance of asphalt concrete were tested. The results showed that PPWC filler has a smaller particle size and rougher surface than limestone filler, and it contains Ca(OH)2 produced by hydration. The addition of PPWC filler can effectively improve the mechanical properties of asphalt concrete without reducing its water damage resistance. PPWC filler can improve the high-temperature rutting resistance and low-temperature crack resistance of asphalt concrete, but reduce its low-temperature fatigue resistance. The low content of PPWC filler will enhance the adhesion between asphalt mortar and aggregate. However, when the content of PPWC filler exceeds 50%, Ca (OH)2 in PPWC will reduce the adhesion between acid asphalt mortar and alkaline basalt aggregate. Therefore, the use of PPWC as filler in asphalt mixtures provides a reliable solution for the sustainable development of road materials.

Widespread interest has been drawn to the use of solid waste fillers as a partial replacement for natural fillers in high-performance asphalt mixtures in recent years. However, variations in the material properties of solid waste fillers remain a problem for the recycling method. To address this issue, the limestone powder in asphalt mixtures was replaced with three solid waste fillers, including steel slag powder, tailings powder and calcium carbide slag powder in this study. The chemical composition of the fillers was first characterized to assess the homogeneity of the material. Then, a dense-graded asphalt mixture (AC) and a stone matrix asphalt (SMA) mixture were designed, produced and characterized for wet stability. The results show that the asphalt mixtures with solid waste fillers were superior to limestone powder (LP) asphalt mixtures in terms of resistance to water damage, and the steel slag powder showed the best improvement in moisture stability of the asphalt mixtures. The optimum substitution of solid waste filler for limestone filler was 25%. With the addition of anti-stripping agents, the moisture stability of the asphalt mixture with limestone filler was also greatly enhanced. On the contrary, a marginal enhancement was observed in the moisture stability of asphalt mixtures using solid waste fillers. Solid waste fillers can be used in asphalt mixtures and have a similar function as that of anti-stripping agents. In summary, the use of solid waste fillers to replace mineral fillers in asphalt mixtures is a reliable, value-added recycling option.
