Optimización del diseño de pavimento flexible en un tramo de 4 Km en la vía a Los Lojas, Cantón Daule, Provincia de Guayas, mediante la Integración de RAP (Reclaimed Asphalt Pavement) estabilizado con emulsiones asfálticas.

Abstract

The Los Lojas access road, located in Daule, shows structural deterioration due to recurrent heavy traffic generated by quarrying activities. This project proposes an optimized design of the flexible pavement using recycled asphalt pavement (RAP) stabilized with asphalt emulsions, with the objective of guaranteeing structural efficiency, durability and offering a sustainable solution. It is proposed that the integration of stabilized RAP improves the mechanical properties of the materials, reducing thickness, costs and environmental impacts. The development of the project included topographic surveying with RTK technology, vehicle gauging, laboratory tests and the application of AASHTO-93 and IMT-PAVE software to carry out the designs in accordance with MTOP regulations. The results showed that the use of RAP together with CSS-1h emulsion improves the load capacity and resistance of the pavement, meeting the service requirements. This supports its viability as a technical and sustainable alternative, which promotes the reuse of materials and the creation of resilient infrastructures.
