Abstract

"PROCESSO DE FABRICAçãO EM CONTìNUO DE BETUMES MODIFICADOS POR ELEVADAS CONCENTRAçõES DE POLìMERO E POR REAçãO COM ENXOFRE, PERMITINDO A RECICLAGEM DE PLáSTICOS E DE BORRACHA DE REFUGO E APRESENTANDO PROPRIEDADES ELASTOMéRICAS E TERMOPLáSTICAS". Trata-se de um processo de fabricação em contínuo de betumes modificados por acréscimo de polímeros e reagidos com enxofre. Os aglutinantes provenientes deste processo podem conter quantidades muito elevadas de polímeros associados igualmente aos materiais de recuperação como: borracha, plásticos diversos e lubrificantes de refugo. A mistura em contínuo de vários constituintes betuminosos, através de um misturador estático, conduz a este tipo de aglutinantes, de obtenção impossível com a tecnologia descontínua por batelada. Eles permitem a obtenção de materiais betuminosos com nível muito elevado de desempenhos e de agentes de regeneração dos betumes gastos contidos nos materiais de refugo das estradas, no quadro da reciclagem a quente dos materiais revestidos. Eles contribuem igualmente à obtenção de novas emulsões de aglutinantes muito modificadas, de aplicações múltiplas e, particularmente, para a reciclagem a frio. Este novo processo, por regeneração de betumes gastos contidos nos materiais revestidos de refugo, representa um meio de conversão de refugos e de limitação do emprego de betume e de agregados para pavimentos de estradas.
