“…La combinación del pavimento asfáltico recuperado con estos ligantes se da, ya que generalmente este material reciclado por si solo tiene baja resistencia como material de base o subbase, conduciendo a la pérdida de propiedades mecánicas y de durabilidad de pavimento. Una limitación para el uso de este material es la lixiviación de los desechos al ambiente (Mohanty et al, 2022).…”

“…Residuos de construcción y demolición (C&D): se basan en su mayoría en los escombros que se generan en la industria de la construcción, ya sea en el sector vial, entre otros o en aplicaciones como la reparación, renovación y mantenimiento de cualquier obra, incluyendo materiales como el concreto, acero, madera, etc. Estos materiales tienen un gran potencial para reemplazar agregados naturales en las sub-bases y bases de los pavimentos, mejorando así sus características de estabilización y conservando las características medioambientales (Mohanty et al, 2022).…”

“…One of the best alternative sustainable approaches is to utilize recycled aggregates in road construction [ 1 , 2 , 3 ]. Most of the past research reported that construction and demolition (C&D) materials from the extraction of road and building waste can be employed in highway construction to stabilize disposal problems [ 4 , 5 , 6 , 7 ]. In India, MORTH (Ministry of Road Transport and Highways) has recently chosen to construct rigid pavement over flexible pavements as the life span is more than 30 years.…”

Feasibility Study of Reclaimed Asphalt Pavements (RAP) as Recycled Aggregates Used in Rigid Pavement Construction

Reclaimed Asphalt Pavement (RAP) as recycled aggregates is a relatively new construction process of rigid pavements due to the scarcity and degradation of natural aggregates. This study aims at the sequential characterization of RAP aggregate to obtain optimized proportions for strength. For this purpose, RAP aggregates were used for the replacement of natural aggregates (NA) in the concrete mix which was achieved by varying from 0–100%. Furthermore, zirconia silica fume (ZSF) was used as a partial replacement of the cement in the concrete mix, replacing Ordinary Portland Cement (OPC). Experimental studies have shown that the incorporation of washed RAP (WRAP) slightly reduces the compressive strength of concrete by 2.7–37.35% as compared to the reference control concrete mix. Although the 7-days, 28-days and 56-day compressive strength of WRAP recycled aggregate-based concrete is slightly better than the 7-days, 28-days and 56-day compressive strength of dirty RAP (DRAP) recycled aggregate-based concrete. A similar trend was observed in the flexural strength and split tensile strength of WRAP recycled aggregate-based. Overall, the results show that 40% WRAP recycled aggregates with 10% ZSF as a replacement for cement outperform DRAP aggregates in concrete mixes. According to the ANOVA results, the combination of ZSF and WRAP aggregates met the cement concrete pavement strength standard, thereby contributing to sustainable development. Reclaimed Asphalt Concrete Pavements (RACP) are now seen as a potential and long-term answer to the present environmental and economic crisis.

“…Next is the subbase course, which is immediately below the base course and helps the courses above it to distribute the loads more effectively [8]. It may be made up of soil that has been stabilized or soil aggregate mixtures that let free water drain off the pavement [9]. The lowest layer of the flexible pavement is the subgrade layer.…”

Metal manufacturing produces various types of byproducts and metal waste that have been growing exponentially. The increasing amounts of metal waste are usually disposed of in landfills, which causes soil and water pollution and increases the amount of gas emissions. On the other hand, in the field of pavement construction, the demand for natural materials is increasing rather rapidly. Many studies have suggested utilizing aggregate-like waste material in pavement construction, but there is little to no literature documenting the use of metal strips of different types. The aim of this study is to investigate utilizing the metal waste produced by the Intag Sohar company in layers of flexible pavement. Selected types of metal waste were utilized in the construction of the material used for base and subbase road layers. Three main parameters were studied: the number of layers, the distance between strips, and the direction of the strips. The effect of the metal waste on the pavement material is evaluated using the standard California Bearing Ratio test (CBR), which is the most important indication of the strength of the pavement material. Results show that the highest-quality mix consisted of four layers of metal waste with 1 cm spacing in one direction with CBR% values equal to 118.807%.
