APLICAÇÃO DE ÁGUAS RESIDUÁRIAS NA CONSERVAÇÃO DE ESTRADAS NÃO PAVIMENTADAS

Abstract

Considering the importance of unpaved roads for country functioning, as it promotes the flow of goods, and specifically in the case of sugar plants for machines and implements traffic used in all production processes, including the sugarcane transportation, the objective was to analyze the unpaved roads conservation under the application of wastewater from sugarcane processing, using adapted semi-trailer equipment. The research equipment development was carried out in the municipality of Quirinópolis, State of Goiás. The wastewater used for sprinkling was supplied by Usina Boa Vista, located in the Quirinópolis region - Goiás. Two side roads were used to carry out the evaluations. These are located at Bruacas and Furnas Farms. All treatments consisted of the wastewater application with different equipment, with the first perimeter using an adapted semi-trailer (water belly), the second perimeter with water trucks and the third with no wastewater application. For evaluating treatments, the severity and dimension of the variables, dust cloud, hole or pot, wheel tracks, aggregates segregation and erosion were considered. Averages of the dimension and severity data collected in the experiment were performed and standard deviations were calculated in order to check the discrepancy of the collected data. The wastewater application using the adapted equipment (water belly) provided the best conservation of roads in Bruacas and Furnas Farms during the six days of experimentation, based on the pathologies of dust cloud, hole / pot, wheel trail, aggregate segregation and erosion. Also, based on the reduction of an activity, the use of semi-trailer water tank (water belly) equipment becomes more viable in relation to the use of the water trucks.
