Comparative study on carbon emissions based on scenario uncertainty analysis: A case of asphalt and composite pavements construction in south China

To improve the accuracy of carbon emission accounting results during the construction of asphalt pavement and composite pavement, and clarify the differences in their carbon emission levels during the construction stage, this study developed a comparative life cycle assessment mo...

Retrofitting residential septic infrastructure for decentralised biogas production: a scenario-based circular waste-to-energy assessment in Lagos

Purpose Rapid urbanisation in cities such as Lagos requires decentralised solutions that address energy insecurity, inadequate sanitation and environmental sustainability. This study evaluates the feasibility of retrofitting septic infrastructure within an ageing residential esta...

Mechanical Properties, CO2 Emissions, and Environmental Impact Assessment of Asphalt Pavement Maintenance Containing High-Content RAP Asphalt Pavements

Abstract The global surge in reclaimed asphalt pavement (RAP) generation presents significant sustainability challenges and opportunities for resource conservation in road infrastructure. This study evaluated the feasibility and environmental impact of plant-mixed hot recycling t...

Simulation study on the mechanical evolution law of double-arch tunnel construction without middle drift

The construction method without middle drift can simplify the construction organization process of double-arch tunnels, thereby improving construction efficiency. However, the mechanical evolution of the surrounding rock and support system, as well as the working mechanism of the...
