Previous studies have reported on the concept of using human subjects to rank and differentiate walkway surfaces that vary in slipperiness. Surfaces identified as having different levels of slipperiness, based on the outcomes of human subject walking trials, are then used to validate tribometer slip resistance measurements. This concept was adopted in the development of ASTM F2508-11, Standard Practice for Validation and Calibration of Walkway Tribometers Using Reference Surfaces. Because of a d...

This study investigates the causes of early-age deck cracking for skewed composite adjacent box beam bridges with integral abutments. It hypothesizes that cracking is attributed to (1) asymmetric thermal movements in a skewed deck and (2) thermal restraints from an integral abutment design, as well as box beams and post-tensioned tie rods. To verify this hypothesis, a bridge in Ohio was instrumented for measuring temperature and strain. The field investigation aimed at observing thermal movement...

The extended performance of the concrete bridge deck depends on the concrete’s ability to resist early-age cracks, which are primarily induced by self-desiccation shrinkage. Several studies have been conducted to study the effect of shrinkage on the development of early-age cracks. When concrete shrinkage occurs, its magnitude may account for tensile stresses developing in the concrete deck over time. Therefore, determining when shrinkage stress initiates in concrete is critical to precisely pre...

The presence of clusters in reclaimed asphalt pavement (RAP) is a critical point that affects the RAP homogeneity. In this phenomenon, different RAP particles are working together as a single aggregate. The cluster dissociation occurs during hot asphalt mixture production and compaction in the field. This research is concerned with the impact of the cluster disintegration on the recycled asphalt mixture aggregate properties. Stages of binder extraction were performed in six RAP materials to part...

Angularity is an important aspect of particle morphology, directly correlated to the mechanical response and strength of granular materials. Many researchers have proposed multiple direct and indirect methods such as visual charts, analytical formulas, and advanced image-based techniques for qualitative and quantitative assessment of particle angularity, but no single method has been fully successful in distinguishing all types of particles and obtaining an accurate quantitative value of angular...

Fiber optic sensors have been increasingly utilized in structural health monitoring of large-scale civil structures. Bare fiber sensors are quite brittle, and therefore, their installation and embedment in reinforced concrete elements can be challenging, particularly when using uncommon materials as internal reinforcements in concrete. In the present study, a fiber optic strain sensor is preinstalled on a supplemental bar of adequate length and appropriate diameter. The sensor is attached to a g...
