## 1 Introduction  
The present concern about using natural resources has been relevant in developing new, more sustainable road pavement projects. A sustainable pavement reduces the environmental impact during its construction [1]. One possible approach is incorporating residual materials into the composition of asphalt pavements. This reduces the exploitation of natural resources and decreases the amount of discarded waste [2]. Various studies have investigated the use of alternative waste materials in construction both in Brazil and internationally. Fly ash has been studied for its benefits in construction applications [3, 4]. Iron ore residues are another material under exploration [5, 6], as are various slags, which have been evaluated for their properties and potential uses [7, 8, 9, 10, 11]. Calcined clay has also been examined for its suitability in construction [12, 13]. Construction and demolition waste (CDW) has been shown to have significant potential [14, 15], while ground tire rubber has been studied for its performance characteristics [16, 17, 18]. Additionally, reclaimed asphalt pavement (RAP) is frequently cited in research for its application in pavement materials [19, 20, 21, 22, 23], as also, aspects related to rejuvenation agents are also frequently mentioned when discussing RAP [24, 25, 26, 27]. These materials are commonly investigated for their potential to improve and performance in sustainability construction practices. However, it is crucial that these waste materials provide the layers with adequate mechanical behavior to withstand the traffic loads they will be subjected to. Therefore, the total or partial replacement of virgin aggregates with waste materials is evaluatedboth in the laboratory and in the field through experimental sections. Using the Brazilian mechanistic-empirical method for flexible pavements, which employs the MeDiNa software for computational analysis, the performance of granular materials is primarily assessed through resilient modulus (RM) and permanent deformation (PD) tests in dynamic triaxial tests. These tests apply mathematical models to estimate their behavior [28]. Specifically for the use RAP in base layers, stabilization with asphalt emulsions in cold-mix asphalt plants has been preferentially adopted. However, many of the mechanical behavior analyses of these materials have been conducted using typical tests for hot-mix asphalt mixtures. Some cases of failure have already been reported, with plastic deformation observed in these layers shortly after the release of vehicle traffic. This was observed during a technical inspection carried out on a stretch of the Fernao Dias highway (BR-381 highway), in the interior of Sao Paulo/Brazil, where the samples used in this study were collected. Cold recycled asphalt mixtures (CRAMs) typically consist of RAP, virgin aggregates (for gradation adjustment), stabilized with bituminous binder (asphal emulsion or foamed asphalt), and active filler such as ordinary Portland cement (OPC) or hydrated lime. Despite the use of asphalt and active filler, which increase the mixture's cohesion and stiffness, CRAMs are generally used as base layers due to their low abrasion resistance under heavy traffic loads, especially during the initial curing period. Therefore, a hot mix asphalt layer is usually placed on top of the CRAM [29]. The mechanical behavior of CRAMs is a topic of debate, with some studies considering them as unbound granular materials with higher cohesion [30; 31], while others suggest that exhibit characteristics similar to asphalt mixtures with viscoelastic properties [32; 33; 34]. For exemple, [PERSON] et al. [35] specimens were produced by means of a gyratory compactor (GC) or produced by marshall compactador [36], evaluated by indirect tensile strength (ITS) test [37], and for indirect tensile stiffness modulus (ITSM) test [38]. [PERSON] [39] also evaluated a cold recycled asphalt mixture using 100% RAP with asphalt recycling emulsifying agent as a new pavement base layer, using similar evaluation methods.
