Abstract:
The development of research involving asphalt mixtures is of utmost importance to improve the quality of the road coating layer, as each day the pavements are subjected to high loads to which they were not designed, thus generating permanent deformations and fatigue cracking. Combining sustainability with the economy of pavement execution by taking advantage of alternative materials, emerged asphalt modifiers that work to improve the characteristics of petroleum asphalt cement (CAP) in terms of retarding aging and improving performance. Thus, this research aimed to evaluate the performance of asphalt mixtures type SMA (Stone Matrix Asphalt) using fibers of sugarcane bagasse with length (≤ 20 mm), thus presenting this mixture a longer durability and resistance for use in high traffic highways. Therefore, when performing dosing of asphalt mixtures using the superpave dosing methodology, it was possible to perform mechanical tests for both conventional and SMA-type mixtures, consequently verifying the technical feasibility of this type of mixture on asphalt pavement performance.
