Avaliação da influência do tipo de revestimento de vias urbanas de alegrete quanto ao ruido no entorno e a serventia ao usuário da via

Abstract

This work presentes a study about thein fluence of types of coating of some Alegrete streets in the "ruído no entorno e a serventia ao usuário da via". It uses the metodology recommended by ISO 11819-1:1997 (Statistical Pass -ByIndex), except some modifications due the field of study. For the use avaliation was used "Departamento Nacional de Infraestrutura de Transporte "Norma009/2003, which determines the "Valor de Serventia Atual". Studied streets have, asphalt coating, polyhedral floor and concrete block inter locked, in good and bad conditions. The evaluated streets are: Tiaraju Avenue (two regions), Caverá Avenue, Marechal Castelo Branco Street, Dautro Filho Street and Major João Cezimbra Jaques Street. In each one was obtained the sound pressure of the passing vehicles using the decibelimeter, and registered their velocities, which are necessary to get the Statistical Pass –By Index. For the use evaluation 6 cars passed on the study streets and gave scores acording to how much it is comfortable to the users, giving them a use level mean value. And, finally, was pointed out which of the coating presented the best results acording to the noise generation o the environment and its use, so this study can be used to help determining the type of coating should be used in future Alegrete urban pavements.
