Abstract Steel fiber–reinforced sprayed concrete (SFRSC) is widely used for ground support in underground works. The panel test, as in EN 14488-5, is one of the most common procedures for the quality control of the energy absorption capacity of SFRSC. The test entails the use of large equipment to manipulate and characterize heavy specimens that…

Abstract Modification of asphalt binders has been one of the common techniques to overcome the climatic and traffic-related distresses that develop in bituminous materials. Over the past decade, many new methods of incorporating recycled tire rubber as a modifier have been developed and evaluated by states and county road departments. This study focuses on the…

The ‘In Charge’ report was carried out in Spring 2021 and surveyed 200 senior executives from across the European battery industry. It found that 84 per cent of UK companies are looking to bring parts of their supply chain closer to their manufacturing base over the next twelve months. Nearly four-fifths (77 per cent) of…

Abstract The shear behavior of coal-fouled unstabilized ballast and that stabilized with Elastan was assessed in direct shear mode at various normal stresses ( σn ) and shearing rates ( Sr ). The materials used in the test were fresh granite ballast and coal fines of mean particle sizes ( D50 ) of 42 mm and…

The 48-hour event saw experienced Siemens engineers working alongside graduates and apprentices in a virtual sprint. Teams used planning and simulation software for manufacturing operations and factory simulation software to design the new production facility, which is due to open in 2024. Riversimple’s fully hydrogen-powered Rasa vehicle will be produced at the plant, with the…

Abstract This note reports the physical and mechanical properties of two postwildfire sands collected in Southern California and chemically induced hydrophobic sand. Hydrophobicity decreases the attraction between water molecules and solid surfaces and manifests a modification of hydraulic soil properties that lead to postwildfire rain soil erosion and mudflows. Wildfires induce different hydrophobicity levels in…
