The main network of roads of the country is asphalted pavement. Finding a way to improve the technical properties of asphalt has attracted the attention of experts in recent years. Nanomaterials can be used to improve the technical properties of asphalt. On the other hand, fibrous materials can also be used to arm the asphalt mix. In this context and in this article by adding different percentages of nano-carbon black marshall experiments, analyze data and plot it was noticed that the addition of these additives increases the resistance of marshall and decrease of flow. On the other hand, resistance was increased by adding industrial polyester fibers to asphalt mixtures and in low percentages. Psychosocial rose as the percentage of industrial fiber polyester increased. Other results also changed. Economically, the results indicated that the use of fibers in general is preferable to nano-materials and its use in asphalt mix is recommended. Finally, by comparing the results, it was concluded that the blend containing black nanocarbon is more rigid than the mixture containing industrial polyester fibers, and it can be used in the regions with tropical weather and so much traffic and with more traffic and limited use.
