Insitu Measurement of Pavement Distress and Causal Mechanisms in Expansive Soil along Alabama Highway 5
(2016-12-08)
Alabama Highway 5 is a farm-to-market road built directly on an expansive clay subgrade. Moisture fluctuations cause the soil to shrink and swell, resulting in severe pavement distress. Laboratory testing has been performed ...
Quantifying the Fatigue Damage Accumulation in Bridges
(2019-12-05)
Many of the existing bridges in the United States were built during the interstate era and are reaching the end of their life cycle. Traffic-induced loadings are one of the primary factors affecting the service and fatigue ...
Early Characterization and Performance of a Flexible Thick Lift Pavement
(2019-12-05)
The South Carolina Department of Transportation (SCDOT) has recently been experimenting with thick lift paving to increase construction speed and facilitate faster access to traffic. However, there has been limited research ...
Qualifying the Saturated Hydraulic Conductivity and Corresponding Infiltration Processes
(2019-12-05)
Many engineering systems such as the hydraulic barriers and infiltration practices are designed based on the understanding of water infiltration through the subsurface. Among the soil hydraulic properties, the saturated ...
A New Class of Adsorptive Photocatalysts for Enhanced Adsorption and Destruction of 4-chlorophenol and perfluorooctanoic acid
(2019-12-05)
Four novel Ti-based adsorptive photocatalysts, namely titanate nanosheets (TNS), graphene grafted titania/titanate nanosheets (G/TNS), activated carbon modified titanate nanotubes (TNTs@AC), and iron doped, activated carbon ...
Braking Forces in Highway Bridge Substructures
(2019-06-24)
Under the Load-and-Resistance Factor Design Specification, the longitudinal braking force that must be designed for was increased when compared to a bridge designed according to the previous code, the Standard Specification. ...
Analysis of Freeway Traffic Operations using Driver Assistive Truck Platooning Technology
(2016-07-26)
Driver assistive truck platooning (DATP) as an application of cooperative adaptive cruise control is expected to have substantial benefits in the freight industry. This FHWA study looks into the benefits of DATP in the ...
Pore Scale Methods to Enhance Understanding of Geochemical Reaction Rates in Porous Media
(2019-07-23)
Geochemical reactions play an important role in subsurface systems such as in contaminant fate and transport, chemical weathering and geologic carbon sequestration. These reactions, mainly dissolution/precipitation, will ...
WIM-Based Live Load Model for Bridges
(2018-04-24)
The knowledge of the actual live load is essential for a rational management of highway structures. Overloaded vehicles can cause damage including concrete cracking, potholes, excessive vibration and deflection, and even ...
Theoretical Moment-Rotation Curve for Steel Piles Embedded in Concrete
(2017-07-31)
The accurate modelling and analysis of connections formed by embedding steel piles in concrete is a difficult undertaking that has only recently begun to receive attention in the research community. These connections are ...
