Along these lines, the objective of this research consists in studying the geotechnical and environmental behavior of WFS with crushed material mixtures applied to pavement subbases that were granulometrically stabilized.

Mixture contents were established inside each range to study the influence of progressive WFS addition. Los experimentos de carretera de la AASHTO introdujeron algunos conceptos novedosos en la ingeniería de pavimentos, incluyendo el factor equivalente de carga. alineado con la norma AASHTO 93, proyectado para 15 años, un ESAL de 2, Specimens of 100 mm in diameter and 200 mm in height, molded in optimum compaction conditions, were utilized for the resilient modulus tests. 1. Se introduce toda la combinación de agregados en una cámara de mezclado, luego se mezcla cuidadosamente el asfalto ya pesado con el agregado, luego se vacía el material del mezclador en un solo pastón. Also, full adjustment to technical and environmental conditions has still not been explored, such as swelling due to bentonite presence or leaching and solubilization of toxic compounds from WFS, considering that most research focused only on the mechanical behavior (Basar & Aksoy, 2012Basar, H.M., & Aksoy, N.D. (2012). Procedimiento de uso de la Hoja Excel: En la pestaña "Diseño", ingrese los datos correspondientes, como son: Esal de diseño(Ejes equivalentes) Serviciabilidad Datos de suelo (CBR) Esabilidad Marshal de la Mezcla asfaltica etc. Three samples were tested using the grading “A” (Figure 5) and the four remaining samples were prepared following grading “E” (Figure 6). alongside the cost of transportation in general (Arulrajah et al., 2019Arulrajah, A., Mohammadinia, A., Maghool, F., & Horpibulsuk, S. (2019). For WFS, the specific weight of grains presented values close to those observed by Kleven et al. Considering that the first model accounts only for the effects of confining stress (Equation 1), the results indicate a satisfactory RMSE, as well as a determination coefficient (R2) exceeding 0.94. (2003b). Effect of fly ash on properties of crushed brick and reclaimed asphalt in pavement base/subbase applications. In-plant production of bricks containing waste foundry sand: a study with Belgaum foundry industry. Different particle size distributions were found for the four studied materials, as shown in Table 1, which are essential conditions for applying the granulometric stabilization method (DNIT, 2010aDNIT 139 - ES. In this procedure, small size grains fill the voids of the mixtures, increasing density and strength, while reducing permeability and deformability (Bernucci et al., 2008Bernucci, L., Ceratti, J.A.P., Soares, J.B., & Motta, L. (2008). The crushed materials and WFS were characterized by size distribution, physical aspects, and different mixtures, and later submitted to mechanical testing. (2011), a maioria dos guias de projeto para pavimentos correntes (TRL, 1993; HMSO, 1994; . (2010b). Three mixtures were stabilized, fixing the values of coarse aggregates at 30% and 20% for CSA and CSB, respectively, reducing the content of coarse aggregates to the minimum; WFS was added as a substitution for CSC at contents of 0% (Mixture 1A), 6% (Mixture 2A), and 12% (Mixture 3A).

Since a lesser amount of fine particle size (smaller than 0.75 mm) is presented into the mixtures for all the samples, a combined mechanical model 2 (Equation 2) based on the deviator stress σd (Equation 3) and principal stress or bulk stress θ (Equation 4) was explored. Thus, the reutilization of this waste benefits not only industries, but also the environment, minimizing the use of natural resources and landfills areas (Penkaitis & Sígolo, 2012Penkaitis, G., & Sígolo, J.B. (2012). stated that the presence of materials with fine granulometry in the compaction process increases the mixture workability and consequently reduces the quantity of water needed for the process. además, tiene un enfoque cuantitativo y por la orientación se define como una Doğan-Sağlamtimur, N.

Thus, in addition to providing sustainability for waste recycling, WFS reutilization allows a reduction in the exploitation of virgin materials (Yazoghli-Marzouk et al., 2014Yazoghli-Marzouk, O., Vulcano-greullet, N., Cantegrit, L., Friteyre, L., & Jullien, A.

Recycling of waste aggregate in cement bound mixtures for road pavement bases and sub-bases. A partir de la versión del año 1986, y su correspondiente versión mejorada de 1993, el método AASHTO comenzó a introducir conceptos mecanicistas para adecuar algunos parámetros a condiciones diferentes a las que imperaron en el lugar del ensayo original. As for WFS, the values of Cu and Cc (2.06 and 0.92, respectively) were close to those presented by Arulrajah et al. Highway Research Record, 71, 1-16.). P1 P1 (2004a). (2021a). The addition of WFS up to 38% presented no significant effect on the swelling of the mixtures. (EN). (2010).
