Behavior of the cast-in-place splice regions of spliced I-girder bridges
(2015-08)
Spliced girder technology continues to attract attention due to its versatility over traditional prestressed concrete highway bridge construction. Relatively limited data is available in the literature, however, for ...
Kinetics of ciprofloxacin degradation by ozonation : effects of natural organic matter, the carbonate system, and pH
(2010-08)
The presence of pharmacologically active and persistent compounds in drinking water sources is an environmental and public health concern. Sources of pharmaceuticals in the aquatic environment include wastewater treatment ...
Development and application of a production rate resource for contract time determination
(2017-05)
Production rates are significantly important for contract time determination procedures as these are essential for estimating the duration of every activity needed to complete a highway construction project. For this reason, ...
Now on TAP : accelerated solutions to the traffic assignment problem
(2019-08-09)
The traffic assignment problem (TAP) represents the final and most computationally difficult step in the Urban Transportation Modeling System (UTMS). Prior work has studied several means of solving this problem quickly. ...
Risk analysis in tunneling with imprecise probabilities
(2010-08)
Due to the inherent uncertainties in ground and groundwater conditions, tunnel projects often have to face potential risks of cost overrun or schedule delay. Risk analysis has become a required tool (by insurers, Federal ...
Optimizing cross-dock operations under uncertainty
(2011-12)
Cross-docking is an important transportation logistics strategy in supply chain management which reduces transportation costs, inventory holding costs, order-picking costs and response time. Careful planning is needed for ...
Study of sustainability opportunities during construction
(2014-05)
Construction Sustainability involves the processes, decisions, and actions during the construction phase of capital projects that enhance current and future environmental, social, and economic needs while considering project ...
Evaluation of the curing time and other characteristics of prime coats applied to a granular base
(2011-05)
Prime coats have been in use for many decades to help protect the base before the subsequent application of bituminous surface treatments. Prime coat is an application of a low viscosity binder onto the base to help protect ...
Seismic behavior and design of low-rise reinforced concrete masonry with clay masonry veneer
(2010-05)
The research described here is part of a multi-university project on “Performance-based Design of New Masonry Structures.” Within the context of that project, the main objectives of this research was to study the inelastic ...
Revamping aggregate property requirements for portland cement concrete
(2012-05)
Current Texas Department of Transportation (TxDOT) procedures for evaluating coarse aggregate for portland cement concrete (PCC) have been in place for over 39 years. Item 421 in the TxDOT "Standard Specifications for ...
