Evaluation of Steel Fiber–Reinforced Sprayed Concrete by Energy Absorption Tests | Journal of Materials in Civil Engineering

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…

Effect of Devulcanized Rubber Modification on the Performance Grade, Fatigue Cracking Resistance, and Rutting Resistance of Asphalt Binders | Journal of Materials in Civil Engineering

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…

Influence of Coal Fouling on the Shear Behavior of Elastan-Treated Railroad Ballast | Journal of Materials in Civil Engineering

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…

Assessment of Physical Properties of Water-Repellent Soils | Journal of Geotechnical and Geoenvironmental Engineering

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…
