Trabalhos Futuros

Para o futuro, para além de uma investigação aprofundada do desempenho das misturas betuminosas temperadas a longo prazo, é imprescindível a quantificação dos benefícios obtidos com a sua aplicação, nomeadamente a nível da comparação entre estruturas contendo misturas betuminosas a quente, com e sem incorporação de material fresado, e de misturas betuminosas temperadas com incorporação de material fresado.

A nível nacional parece então impreterível que os Donos de Obra estimulem a utilização destas tecnologias, incentivando e premiando as empresas construtoras que o façam, devido aos benefícios ambientais daí provenientes.

Este trabalho deixa ainda em aberto a possibilidade da criação de uma especificação nacional para uma metodologia de formulação deste tipo de misturas, o que auxiliaria a sua implementação e divulgação no nosso país.
