“…Construction and demolition waste is increasingly being recognized as a potential resource due to a shortage of high-quality materials and the increasing cost of natural aggregate [10][11]. Recycled concrete aggregates (RCA), which make up around 70% of construction waste, have been shown to be particularly helpful in constructing flexible pavements with good performance and durability [12]. This is essential not only for cutting down on construction expenses but also for mitigating the environmental consequences associated with road development.…”

The use of various reclaimed or recycled materials from ancient structures as a source of construction materials has become common in modern road and pavement engineering procedures due to the shortage of fresh natural aggregate supplies and rising processing prices. Waste ceramic tiles (WCT), reclaimed asphalt pavement (RAP), and recycled concrete aggregate (RCA) have all been used for a long time as aggregates in the construction of pavement. WCT, RAP, and RCA are all thoroughly analyzed in this paper, with a focus on their mechanical, environmental, and physical properties. To evaluate the load-bearing ability, drainage capabilities, and long-term durability of these substitute materials when applied as pavement sub-base, laboratory tests and performance analysis were carried out. Since different mixtures of these materials are created, the maximum California bearing ratio of 25.54% is found. By promoting the usage of recycled materials, eliminating waste, and lowering the carbon footprint associated with conventional construction processes, this initiative helps to sustainably build out transportation infrastructure.

“…C&D waste material is becoming a more valuable resource every year due to factors such as the unavailability of high-quality materials and the high cost of natural aggregates and in various geotechnical engineering applications, such as pavement, soil improvement, engineering fills, pipe beds, backfill and offshore reclamation, it is increasingly used 1 – 5 . RCA, which makes up the vast majority of C&D waste material, is an attractive alternative in road engineering, especially for designing well-performing and long-lasting flexible pavement systems 6 , 7 .…”

The use of recycled concrete aggregates (RCA) not only reduces the demand for natural aggregates (NA) but also might improve the behavior of soil under earthquake loading. In this study, the behavior of the pavement constructed using 100% RCA and NA on a sandy soil layer with high liquefaction potential under dynamic loads was investigated by numerical analysis and compared with free field conditions. For this purpose, first, the classical geotechnical properties of 100% RCA and NA materials were obtained, and then the stiffness properties were determined by resilient modulus and permanent deformation tests. In the second stage, three different models were created with pavement with NA and RCA and without pavement on high liquefaction potential sand, and dynamic analyses were carried out by PM4Sand. Numerical analyses show that constructing a subbase and base layers significantly reduces liquefaction-induced settlement on the surface of flexible pavements built on liquefied soils. Moreover, when the case of using RCA instead of NA in the subbase and base layers built on the liquefied soil is examined, the liquefaction-induced settlement values on the surface are obtained either lower or very close. Consequently, this study proposes a new alternative to the use of RCA waste materials instead of NA. It is expected the use of these waste materials will reduce the need for storage space and also reduce the negative environmental effects associated with storage.
