Transporte, trânsito e meio ambiente: um olhar para o transporte de pó de brita com cobertura de lona para caminhões do transporte urbano.

Abstract

The objective of this work was to analyze the losses of gravel dust due to the non-use of tarpaulins in urban cargo transport trucks on public roads, through a case study and comparative analysis of its results. The survey of cargo losses was carried out based on the methodology of Rocha and Cardoso (2020), and a questionnaire was applied in order to analyze the main means that losses occur and to collect the experience of workers in the transport of this material. From the analysis of the data and results obtained, it was possible to verify the loss of gravel dust, taking into account the economic cost of this material, thus being able to evaluate the economic advantages that the use of tarpaulin brings to the fine aggregates sector. The results of the weighings showed that the company studied, in one year, saved about 34,467.18 kg of crushed stone dust, which is equivalent to R$1,585.49. Through the application of the questionnaire, it was identified that the main obstacles in the waste of gravel dust are the lack of canvas, the lack of sealing in the bucket and the holes in the track. Finally, the hypothesis was confirmed by proving that non-compliance with the regulation of the use of canvas in trucks causes waste in the transport of gravel dust, with economic losses.
