Permanent deformation is one of the main causes of the early deterioration of the asphalt layer of roads. This type of phenomenon is driven in the country due to the heavy vehicle load and the climatic variety, in particular, the high temperatures. It is known that the behavior of the asphalt mixture depends directly on the materials that make it up. And in challenging conditions, these materials are insufficient. In this sense, the present research seeks to improve the properties of a conventional asphalt mixture by adding basalt and lignin fibers, in such a way that it is less prone to permanent deformation. For the experimental part, it was used aggregates from the Conchán quarry, in Lima. Using Marshall's methodology, two asphalt mixes were designed. The first mixture was made without additives and based on technical files in the area. The second mixture was made with the same components and with the addition of 0.3% basalt fibers and 0.3% lignin fibers. The samples were subjected to stability and flow tests, stiffness index, mineral aggregate voids and compressive strength. The results of the investigation showed that when incorporating basalt fibers and lignin fibers the stability of the mixture is obtained in 7%, the Marshall stiffness index in 6%, the percentage of voids of mineral aggregate in 2% and the resistance a compression in 4%. From the foregoing, it can be inferred that the proposed asphalt mix has a greater capacity to distribute the load, greater resistance to creep deformation, greater expansion capacity to counteract high temperatures and, consequently, greater resistance to permanent deformations.
