Estudo comparativo do processo de produção de mistura asfáltica

Abstract

The best performance of a pavement necessarily passes by appropriate structures and compositions, becoming required knowledge of each stage of production and all that is directly and indirectly linked to the same, so that the manufacturing process and execution of the Brazilian pavements can be improved. The present work it’s a comparative study, for academic purposes, related to the current process of asphalt mixture in Asphalt Plant of Toledo-PR. At first, there was a study in bibliographies about the pavement, their ratings and structures. In addition, were indicated the types of asphalt binders and the different mixtures machined. Moreover, were presented the methodologies adopted in the production of asphalt concrete in other Brazilian asphalt plants. The adopted methodology is based on the qualitative method, with field observations and monitoring of the production process of asphalt mixture along with the professional responsible. It’s detailed the form of obtainment and storage of raw materials and the final destination of the production residue. In addition, the entire process of improvement of asphalt mixture in Asphalt Plant of Toledo-PR was characterized. From this, it might perform a comparison between the methodology found with the studied in bibliography.
