Evaluation of Specialized Concretes for the Repair of Damaged Continuity Joints in Prestressed Girder Bridges
(2021)
Precast, prestressed concrete simple span girder bridges made continuous through the use of continuity joints exhibit a great, structural advantage when dealing with additional dead and live loading across the deck. ...
Identification of Piecewise Flexural Rigidity of a Prestressed Concrete Bridge Girder
(2019)
Aging infrastructure calls for structural health monitoring for recommendations on load postings, retrofitting, or replacements. Flexural rigidity identification has been used to monitor aging precast pretensioned concrete ...
Evaluating the Effects of Vegetation Cover and Phenology on the Components of the Surface Energy Fluxes, Soil Temperature and its Damping Depth, Soil Moisture and the Partitioning of the Evapotranspiration Across Forest, Grassland and Desert Ecosystems
(2020)
The understanding and modeling of the effects of land-cover change on the behaviors of evapotranspiration flux and its partitioning, soil moisture, soil temperature, and surface energy fluxes which include ground heat flux, ...
Comparative Study of Surface Preparation And Bond Angle Combinations For Bridge Repair Using Ultra-High Performance Concrete Alternative
(2018-12)
Ultra-high performance concrete (UHPC) is a type of concrete with advanced mechanical properties compared to normal strength concrete and that can be used for connections and repairs in bridges. Most UHPC used in the field ...
Laboratory study of durability of recycled concrete aggregate including drainage for use in pavement base course
(2023)
Recycled concrete aggregates (RCAs) have been used as a cost-effective and environmentally friendly material in pavement base construction for quite some time. However, there is a lack of information on the durability, ...
Quantifying Solar-Powered Removal of Aqueous and Gaseous Sulfide in a Mine Water Passive Treatment System
(2018-12-14)
Passive treatment systems can improve water quality for mine water discharges. However, some process units, like vertical flow bioreactors (VFBRs), may produce excess sulfide, which can be a source of nuisance odors and ...
Design Guidance for Installing Vibration Sensitive Equipment in Industrial Facilities
(2016-08)
The need to understand floor vibrations in an industrial facility has increased in recent years as the drive for tighter manufacturing tolerances has increased. This drive has led to an increase in manufacturing equipment ...
RHEOLOGICAL PROPERTIES OF POLYMER AND RAP MODIFIED ASPHALT BINDERS USING MULTIPLE STRESS CREEP AND RECOVERY METHOD
(2016-12)
In recent years, asphalt modifications have become increasingly popular in asphalt pavement construction. Also, in view of technical, environmental and economic benefits, the pavement industry is in favor of using high ...
EFFECTS OF SEISMIC LOADING ON OKLAHOMA HIGHWAY BRIDGES
(2016)
Since 2006, the number of magnitude (M) 3.0 and larger earthquakes occurring in Oklahoma
has increased dramatically. Large magnitude (> 5:0) events have caused damage
to residential structures, which raises a concern ...
Investigation of Chemically Prestressed Concrete
(2018-05-12)
This research investigated the possibility of prestressing a concrete element by inducing expansion of the concrete paste at an early age. This behavior is being called chemically prestressed concrete, for this project, ...
