Effect of Dispersed Reinforcement on Ultrasonic Pulse Velocity in Stabilized Soil. [PDF]
Materials (Basel), 2021 One of the fundamental techniques for road subgrades is soil stabilization. Considering the high emission of carbon dioxide during the production of binders, novel techniques to reduce the binder are being studied. Thus, we investigated dispersed reinforcement in stabilized soils. A study was conducted to determine the ultrasonic pulse velocity in nine
