Metodología para diseño de pavimento asfaltico reciclado, y su aplicación en capas de rodadura de vías urbanas

Abstract

This research is of utmost importance in the current context, aligning with the growing demand for sustainable construction practices and environmentally friendly approaches in civil engineering. The adoption of Recycled Asphalt Pavements (RAP) not only efficiently addresses construction waste management but also promotes resource efficiency and contributes to reducing the carbon footprint associated with road construction. The choice of the stretch on the state network E-489, specifically between Progreso and General Villamil Playas, provides a realistic scenario to evaluate the characteristics of PAR under traffic and load conditions typical of urban roads. The set objectives were comprehensively addressed. The review of bibliogPARhic fundamentals and technical normative criteria related to PAR was based on references from recognized entities such as ASSTHO and MTOP. The identification of specific characteristics and applications in the wearing course layers of urban roads was carried out considering local regulations, such as the "General Specifications for the Construction of Roads and Bridges" established by the MTOP. The proposed methodology, divided into key processes from PAR sampling to designing asphalt mixes with different percentages of PAR, was grounded in technical principles supported by recognized regulations and standards, including references from ASSTHO and MTOP to establish the minimum characteristics to be met in the design. The obtained results confirmed that the inclusion of 25% recycled material in the asphalt mix proved optimal, meeting crucial parameters and achieving an effective balance between sustainability and structural performance
