Empirical modeling of the relationship between decision sight distance and stopping sight distance based on AASHTO [PDF]
Archives of Transport, 2018 The paper introduces implementation of highways' stopping sight distance (SSD) and decision sight distance (DSD) based on AASHTO modeling assumptions. SSD characterizes the necessary distance for highway vehicles to stop safely in front from an obstacle.

Development of an AASHTO Guide Specification for UHPC
Second International Interactive Symposium on UHPC, 2019 The widespread, growing interest in the United States in using ultra-high performance concrete (UHPC) in engineered structures is being hindered by a lack of structural design guidance relevant to this class of materials. The material characteristics that form the foundational inputs for existing reinforced concrete design specifications do not ...

Mechanics‐based model for cold joints in reinforced concrete members
Structural Concrete, EarlyView.Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Structural Concrete, EarlyView.Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.
