Abstract: This paper presents a numerical study on culverts under rigid pavements subjected to static traffic loading. The numerical study was based on the results of a comprehensive field study of a single-cell low-fill box culvert ...

Abstract: Expansion and contraction of an integral abutment bridge cause an abutment to move toward and away from its backfill due to seasonal temperature changes, thus causing high horizontal earth pressures behind the abutment and ...

Abstract: In this study, a subsidence simulator, also known as a trapdoor, is used to evaluate stages of soil arching (a load transfer mechanism), and related failure features are imaged using time-lapse surface-wave analysis in ...

Abstract: Geogrid (uniaxial or biaxial) is one type of geosynthetics that has been successfully used in slopes, walls, roads, and other applications. The main application of biaxial geogrid is to stabilize soft subgrade and reinforce ...

Abstract: The use of recycled asphalt pavement (RAP) materials for roadway construction is a sustainable approach and has received more attention in the recent years. However, permanent deformation, or rutting, is one of the concerns ...

Abstract: Mechanically stabilized earth (MSE) walls often include galvanized steel strips as mechanical reinforcement within layers of specified backfill material. Galvanized steel reinforcement provides considerable tensile strength; ...

Abstract: Approach slabs are commonly used to smooth the transition between an integral bridge abutment and its adjacent backfill-supported pavement where differential settlement may exist. This settlement can be aggravated by ...
