Resumo: This work presents the results of a research on the technical feasibility of the use of asphalt-rubber binder by the asphalt paving industry. In Brazil more than 30 million tires a year are disposed of, mostly in inadequate sites, causing serious health and environmental problems. The effects of the main factors (rubber content, rubber particle size, temperature of mixture, reaction time) on the behavior of asphalt-rubber binders are evaluated by traditional and Superpave Method tests, the latter based on certain fundamental properties directly related to field performance. Results of the statistical analysis of the factorial design of laboratory experiments show the most significant effect of rubber contents, or rather, that asphalt-rubber binder may increase the resistance against permanent deformation and fatigue cracking

Trata-se de uma alternativa para solucionar um grave problema ambiental, pois no Brasil, anualmente, são descartados mais de 30 milhões de pneus, dos quais a maior parte é disposta em locais inadequados, servindo para a procriação de vetores de doenças e representando risco de contaminação do meio-ambiente. Os efeitos dos principais fatores que condicionam o comportamento do ligante asfalto-borracha (teor e granulometria da borracha, temperatura de mistura, tempo de reação) são avaliados através de ensaios tradicionais de caracterização de ligantes asfálticos e ensaios do Método Superpave, diretamente relacionadas ao desempenho dos pavimentos no campo. Os resultados da análise estatística evidenciam o efeito preponderante do teor de borracha e, principalmente, que o ligante asfalto-borracha pode aumentar a resistência ao acúmulo de deformação permanente e ao aparecimento de trincas por fadiga do revestimentoUniversidade Estadual De Maringá2008-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/280410.4025/actascitechnol.v23i0.2804Acta Scientiarum.
