Pretensioned concrete girders are currently fabricated using 0.5- or 0.6-in. diameter prestressing strands. In recent years, however, it has become of interest to employ larger-diameter 0.7-in. diameter strands to reduce ...

This thesis presents the investigation towards increasing the understanding of the effect of polycarboxylate (PCE) High-Range Water-Reducers (HRWRs) on the performance of concrete mixtures, with a special focus on concrete ...

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, ...

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. ...

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 ...

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 ...

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 ...

This thesis compares actual and perceived travel times and presents a model for predicting traffic flows when there is a network disruption. The goal of this research is to demonstrate the necessity of accounting for ...

This thesis presents a study on the dynamic characteristics and seismic performance of a retrofitted concrete building located in the soft soil area of Mexico City. The original structure consisted of reinforced concrete ...

This work presents two mechanisms for modeling alliance formation between leader carriers in a freight network for more efficient utilization of their resources: partial collaboration and complete collaboration. The ...
