Resumen
Pavements are exposed to environmental conditions and vehicle loads that cause them to age. Due to the high demand for pavement construction and the scarcity of resources, it is necessary to implement materials such as RAP (Recycled Asphalt Pavement). In this project, a comparison was made of the physical and rheological properties of a 100% virgin asphalt mix and one with 20% RAP. To do this, softening point, penetration and viscosity tests were performance to asphalt, and Marshall test was performance to pavement. These indicated that aging caused a hardening in the asphalt. The Marshall test yielded good results, so it is possible to use asphalt mixes with 20% RAP.
