N2 - In recent years, the growth of the automotive fleet in Lima has caused its main roads to experience fatigue failures in the asphalt layer due to permanent deformations that affect the pavement’s useful life. Warm Mix Asphalt meets the sufficient requirements to improve the structural behavior of flexible pavements. They have similar or superior behavior to conventional asphalt mixtures since they reach higher compaction densities. This allows a reduction in the aging of the binder, which works at lower mixing and compaction temperatures. The use of rubber in the warm mix not only improves the strength of the asphalt mixes but also improves durability, rutting, and fatigue. The laboratory results, the product of the softening point, and penetration tests show that the Warm Mix Asphalt with 18% recycled rubber reduces the deformations caused by fatigue by 50% when experiencing a cyclic load of 650N and 1300N, which represents felt the traffic congestion. In conclusion, it can be said that the Warm Mix Asphalt with the addition of recycled rubber improves the permanent deformations of the pavements, as a result of a higher viscosity in the mixture and a greater amount of air, which gives greater rigidity to the asphalt binder.
