A contribution for a sustainable, resilient road infrastructure management from...
Vieira, Carina; Correia, Eugénia; Domingues, Daniela; Rato, Maria João; Caetano, Fernanda; Borges Miranda, Henrique; Carvalho, ManuelaNowadays, there are increasingly efforts to introduce an economy based on circularity principles, but there is still a gap between the intentions and the actual measures to achieve it. In Portugal, reclaimed asphalt is generally used as granular material for unbound road layers or reused mainly as asphalt mix in the municipal road network, instead of reusing this premium material in new asphalt mixes for medium...
Influence of recycled plastics on the mechanical behaviour of bituminous mistur...
Borges Miranda, Henrique; Domingues, D.; Rato, M. J.Europe is one of the largest producers of plastics in the world, with an annual turnover of over 350 billion euros, making it a strategic industrial sector as the global consumption of plastics increases. However, plastic is nowadays considered a serious environmental problem as it represents a large share of the world’s waste generation, with Europe being one of the largest sources of plastic waste exports. Th...
Pavimentos sustentáveis com incorporação de plásticos reciclados
Rato, Maria João; Domingues, Daniela; Borges Miranda, Henrique; Antunes, VítorOs resíduos de plástico apresentam-se como um desafio ambiental significativo e crescente, incluindo desde plásticos industriais, sacos de plástico, embalagens para alimentos, entre outros. Em resposta à crescente preocupação, tem havido um progressivo interesse na incorporação destes resíduos em outras aplicações, nomeadamente, a incorporação de resíduos de plástico reciclado em materiais de construção. Mas se...
Influence of laboratory aggregate compaction method on the particle packing of ...
Borges Miranda, Henrique; Batista, Fátima Alexandra; Antunes, Maria de Lurdes; Neves, JoséThe type of aggregates and their packing characteristics under compaction are key factors for the design of asphalt mixtures with improved performance, namely, with respect to resistance to permanent deformation. A good example is Stone Mastic Asphalt (SMA), known by its stone-on-stone structure. In the U. S.A., the aggregate particles packing characteristics in a SMA, specially the stone-on-stone effect, are n...
Influence of the aggregate skeleton matrix and volumetric composition on the re...
Borges Miranda, Henrique; Batista, Fátima Alexandra; Neves, José; Antunes, Maria de LurdesThe influence of different aggregate skeleton matrices, as well volumetric composition and mixture stiffness, on the resistance of SMA to permanent deformation was assessed. Nine SMA withdifferent optimised aggregate skeleton matrices, studied elsewhere, were now evaluated to permanent deformation with wheel tracking. The results were statistically analysed concerning relationship withspecimens' volumetric char...
