Geotechnical constructions involve consumption of a vast amount of non-renewable natural resources and energy- and carbon dioxide-intensive materials (e.g. cement and steel) that contribute significantly to global warming and climate change. This paper uses drilled shafts as an example to illustrate the importance of environmental impact assessment in the design phase of foundations. Life-cycle assessment

Development of sustainable prefabricated housing system by small-scale experimental model Proc. Inst. Civ. Eng. Eng. Sustain. (IF 1.2) Pub Date : 2022-05-03 Ravijanya Chippagiri, Ana Bras, Rahul V Ralegaonkar
Utilisation of unused industrial wastes and the need for rapid volumetric construction led to the evolution of sustainable prefabricated housing elements, particularly for urban slums. An agro-industrial by-product as raw material and waste expanded polystyrene beads as the insulation material are chosen to develop a lightweight prefabricated construction element. This bio-ash is used as a partial

Sustainable paving alternative for low-volume roads using cold recycled asphalt Proc. Inst. Civ. Eng. Eng. Sustain. (IF 1.2) Pub Date : 2022-04-27 María Elena Araneda, Mauricio Pradena, Rodrigo Silva, Marcos Pardo
Reclaimed asphalt pavement (RAP) is a waste generated by removing asphalt material from a pavement. If RAP is not recycled, the pavement will require new asphalt layers, typically formed by virgin materials (bitumen and aggregates). One way to recycle RAP is by applying the cold-asphalt technique with bitumen emulsion as an additive, which potentially has environmental benefits. This technique can
