“…Hydrated lime is employed to limit moistureinduced damage and chemical ageing of the bitumen (Little & Petersen, 2005). Moreover, it stiffens the mastic better than normal mineral filler, this can be noticed only above room temperature that influences the mechanical properties of the asphalt mixture (Mouillet, Séjourné, Delmotte, Ritter, & Lesueur, 2014). The content of hydrated lime in HMA is always 1-1.5 wt.…”

In this study, the effects of styrene-butadiene-styrene (SBS), American gilsonite (AG) and Iranian gilsonite (IG) usage in bitumen modification, and hydrated lime usage in mixture modification on the performance of hot mix asphalts (HMAs) were investigated. For bitumen modification, 4.0% SBS, 11.0% AG and 10.0% IG were used with respect to bitumen weight. Hydrated lime was used as filler in proportion of 2% with respect to aggregate weight. It was determined that the high temperature properties of bituminous binders were improved with bitumen additive usage. Marshall stability and flow, resistance to moisture-induced damage, indirect tensile stiffness modulus and wheel-tracking tests were applied to the mixtures. The mixture experiments revealed that both HMAs stability and stiffness and also resistance to moisture damage and wheel tracking were increased by hydrated lime and binder additives usage. It was observed that the hydrated lime was not as effective as the binder additives and the most effective additive was usually AG in terms of stability, stiffness and wheel tracking. It was detected that the SBS was the most effective additive for resistance to moisture-induced damage.

“…In response to the increased risk of asphalt pavement damage caused by climate change-induced heavy rainfall and snowfall, the use of slaked lime has emerged as an adaptive reinforcement technique to replace the conventional limestone powder filler in asphalt mixtures [37]. Typically, slaked lime is added to the aggregate before mixing it with the asphalt binder, serving as a substitute filler.…”

Climate change has caused a surge in abnormal weather patterns, leading to a rise in cracks, plastic deformation, and pothole damage on road surfaces. In order to fabricate a ready-mix admixture of warm asphalt mixture (WMA) for pothole restoration, this study aimed to develop a neutralized anti-stripping material in pellet form by extruding a combination of slaked lime and a liquid emulsifier additive. Slaked lime (1% by weight of aggregate) was chosen for its ability to enhance moisture resistance, while a liquid emulsifier (wax + vegetable oil + surfactant + water) was added to create a pellet-type stripping inhibitor for WMA. After successfully fabricating the pellet admixture, this study evaluated the performance of two asphalt mixtures: conventional Slaked Lime Hot Mix Asphalt (LHMA) and the Pellet-Type Anti-Stripping Warm Mix Asphalt (PWMA). Several compatibility tests were conducted to evaluate the quality of the developed material. The results showed that the fatigue resistance of the developed material (PWMA) improved by over 20%, indicating an extended fatigue life for the pavement. The LHMA and PWMA met the quality standard for asphalt mixtures, with a TSR value of approximately 83%. Both mixtures demonstrated improved rutting resistance compared to HMA. The PWMA required 16,500 cycles, while the LHMA required 19,650 cycles to reach a settlement of 20 mm, indicating better moisture resistance than the control mix (13,481 cycles). The modified mixture performed properly in the Cantabro test, with loss rates below 20%, indicating their ability to retain their aggregate structure. The PWMA also showed superior resistance to plastic deformation, with a 12.5% lower phase angle (35°) at a reduced frequency of 10−3. In general, the application of PWMA not only prolongs the pavement lifespan but also reduces the production temperature by over 20 °C, leading to lower emissions and energy consumption. This makes it an environmentally friendly option for pavement applications and contributes to sustainable road construction practices.

“…Uno de los métodos de cuantificación es el método estadounidense, que emplea la espectroscopía infrarroja con transformada de Fourier (FTIR, por sus siglas en inglés) en el cálculo del contenido de cal hidratada en asfaltos. La señal es sencilla de hallar en el espectro y se presenta en longitudes de onda de 1390-1400 cm -1 (Mouillet et al, 2014).…”

“…Emplearon 4 muestras de las cuales 2 contenían cal hidratada en un 25% en masa y la cantidad de cal hidratada posterior a la prueba fue mayor para ambas muestras. Los autores determinaron que no toda la cal hidratada agregada se recuperó debido a las reacciones entre los agregados y la cal (Mouillet et al, 2014).…”

La cal hidratada es un material utilizado normalmente en las mezclas asfálticas, dado que les brinda propiedades únicas y les permite alargar su vida útil. En el presente trabajo se analizaron diversos artículos con el objetivo de comprender los métodos por medio de los cuales se agrega la cal hidratada, la cuantificación del compuesto y la mejora que éste aporta ante diversos factores adversos que acometen a las mezclas asfálticas. Se encontró que los porcentajes usuales en los que se utiliza este aditivo corresponden a un rango entre 1%-2% en peso de los agregados. Asimismo, utilizar cal como un aditivo en húmedo permite mejoras tanto en la dureza del asfalto como en la resistencia contra la humedad, del asfalto. Se concluye que la cantidad de cal hidratada que se debe agregar corresponde al 1,5% en masa de agregados debido a que, en la mayoría de estudios, con esta cantidad se obtuvo las mejores propiedades del asfalto.
