Visando o conceito que o desenvolvimento sustentavel precisa ser capaz de suprir as necessidades tanto da geracao atual como das proximas geracoes sem esgotar os recursos naturais (WWF BRASIL, 2017), este trabalho objetivou-se em reaproveitar o residuo solido gerado pela queima da madeira Pinus nas caldeiras industriais e aplica-lo parcialmente como materia prima, analisando sua viabilidade de utilizacao como filer no concreto asfaltico flexivel e assim diminuir significativamente a extracao dos recursos naturais e o descarte no meio ambiente. Com o intuito que sua contribuicao seja na diminuicao da poluicao gerada pelas industrias, considerando os despejos deste residuo. Tambem contribuindo na melhora significativa da qualidade das rodovias observando-o tecnicamente e viabilizando sua utilizacao na pavimentacao. Para isso, neste artigo sera apresentado os metodos de ensaios utilizados segundo normas tecnicas, observando as alteracoes das caracteristicas dos corpos de prova atraves de calculos e graficos elaborados pelo software Excel. Palavras-Chave: Residuo solido. Concreto asfaltico flexivel. Meio ambiente. ABSTRACT Aiming at the concept that sustainable development needs to be able to meet the needs of both current and future generations without depleting natural resources (WWF BRASIL, 2017), this work aimed to reuse the solid residue generated by the burning of Pinus wood in the industrial boilers and partially apply it as raw material, analyzing its feasibility of use as a filer in the flexible asphalt concrete and thus significantly reduce the extraction of natural resources and disposal in the environment. With the intention that its contribution is in the reduction of the pollution generated by the industries, considering the waste disposal of this residue. Also contributing to the significant improvement of the quality of the highways by observing it technically and making feasible its use in the paving, for this in this article were used methods of tests by the technical norms, observing the changes in the characteristics of the test bodies through calculations and graphs elaborated by the software Excel. Keywords: Solid residue. Flexible asphaltic concrete. Environment.
