Strength of non-traditional granular materials assessed from drained multistage...
Ferreira, S. M. Reis; Correia, A. Gomes; Roque, A. J.When granular materials are applied in geotechnical works, like embankments and road pavement layers, one of the most relevant engineering properties in stability analysis is ultimate shear strength. In geotechnical engineering, the triaxial test is one of the most reliable methods available for determining ultimate shear strength. In this test, a soil specimen, compacted in laboratory or collected from explora...
Main results of the questionnaire for portuguese entities potential users of Co...
Freire, A. C.; Martins, I. M.; Ferreira, C.; Gonçalves, J.; Roque, A. J.Within the framework of the activities of the working group GT1 of the Portuguese Commission on Transportation Geotechnics – Promote the use of non-traditional materials in embankments and structural layers – a questionnaire addressed to potential national entities as construction and demolition recycled materials, C&DRM, producers/users was designed. The main objective was to collect information about the vari...
Technical requirements for the use of C&DW recycled aggregates in municipal and...
Roque, A. J.; Rodrigues, M.; Correia, A. GomesThe use of construction and demolition waste (C & DW) in the construction industry is an important contribution to attain sus- Tainability in the sector. The roads are among the civil engineering works which can use larger quantities of C & DW recycled aggregates. In Portugal, the limit values for the properties of C & DW recycled aggregates that can be used in the roads of Portuguese Road Network are defined b...

Utilização de RCD em estruturas de drenagem de obras geotécnicas
Roque, A. J.; Silva, A. P.; Rodrigues, G.; Almeida, R.O aumento da utilização das matérias-primas secundárias no setor da construção é fortemente incentivado e apoiado pela Comissão Europeia no âmbito de iniciativas como o Horizonte 2020. Este trabalho apresenta o estudo da durabilidade e do comportamento hidráulico de um agregado de betão britado, proveniente de resíduos de construção e demolição. O mesmo estudo foi efetuado com agregados naturais de basalto e de...
