In this context, this study presents the development, construction and validation of a road-degradation test bench designed to simulate, under controlled conditions, the particle emission phenomenon caused by off-road vehicle traffic. The experimental system consists of a metallic cylinder coated with a 3D-printed material that replicates tire tread geometry, actuated by a pneumatic system to move over a bed containing soil materials representative of unpaved mining roads. The test bench is 500 mm long and includes a test section coupled to the wind tunnel, allowing control of aerodynamic and operational conditions during testing. This configuration allows the analysis of the mechanisms governing particle entrainment and transport, correlating variables such as surfaces roughness, rolling resistance and particulate emission intensity. The expected results aim to support the development of dust control and mitigation strategies in mining environments, while contributing to a more comprehensive understanding of the physical processes responsible for dust generation under experimentally controlled conditions that realistically simulate unpaved road degradation. Experimental tests demonstrated the direct influence of moisture content on surface degradation and particle mobilization. At 3% moisture content, significant material disintegration was observed, while at 5%, this effect was partially reduced. At 7% moisture content, a significant increase in surface stability was observed, with less fragmentation and greater resistance to erosion, even at higher speeds.Acesso AbertoEmissão de poeiraVias não pavimentadasBancada experimentalDegradação de viasDust emissionUnpaved roadsExperimental test benchRoad degradationCNPQ::ENGENHARIAS::ENGENHARIA MECANICA::FENOMENOS DE TRANSPORTE::MECANICA DOS FLUIDOSTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
