Abstract: This research presents a practice for quick treatment of voids in airport concrete pavements. Through combining two nondestructive test technologies, heavy weight deflectometry and ground penetrating radar, and polymer ...

Abstract: The facing design of soil nail walls against flexure, punching shear, and headed-stud tensile limit states has been rarely studied within the reliability-based design framework. This study presents reliability analyses of ...

Abstract: Polyurethane grouting technology has been applied in the maintenance and reinforcement of transportation infrastructure such as airports, expressways, and high-speed railways. For rigid pavements with voids underneath ...

Abstract: A novel, resilient, prefabricated, and recyclable retaining system is proposed for underground excavations, comprising a rigid steel frame and flexible steel panels. Laboratory model testing and finite-element simulations ...
