SUMMARY:

Brazil has the road transport mode as its predominant one, accounting for about 60% of all active transport modes in the country. However, this large share does not reflect the quality of its highways. According to the latest survey by the National Confederation of Transport (CNT) (2024), most of the paved network shows defects, causing losses for those who use these roads. To correct pavement defects, several methods are employed, with Full Depht Reclamation (FDR) being one of the most commonly used due to its economic and sustainable advantages, as it allows the reuse of materials and eliminates the need for new inputs. Several studies have been conducted to analyze the feasibility of using waste and by-products in civil engineering, and waste from scheelite beneficiation is one of them.

The scheelite beneficiation process generates large volumes of waste that are disposed of in open areas, causing various environmental impacts. In this context, the present study aimed to analyze the feasibility of incorporating this mineral waste into the FDR process. Recycled mixtures were prepared by adding waste, Reclaimed Asphalt Pavement (RAP), and crushed stone to the base materials collected from Km 51.16 and Km 51.60 of the BR-427 highway. The mixture composed of Base + 50% RAP + 15% Crushed Stone 19 + 20% Waste met all the physical and mechanical parameters required by the standards.
