Determination of the Effective Bond Strength for Near-Surface Mounted Titanium-Alloy Bars in Reinforced Concrete
(2024-04-12)
The repair and strengthening of existing structures have become active research areas in civil engineering with the objective of developing efficient means to extend the service life of bridges to avoid the high cost of ...
Determining the Average Available Workdays for ALDOT Construction Projects
(2023-12-01)
Construction scheduling in the dynamic field of highway projects is complex and time-consuming, with project delays and cost overruns setting critical challenges. This study highlights the significance of accurately ...
Developing a Tool for the Design and Cost Optimization of Permeable Pavements in the Planning Stage of Stormwater Management
(2021-07-12)
Stormwater runoff, when not managed properly, can represent a threat to the environment especially in today’s urban setting. For small pavement applications such as parking lots, conventional pavements and best management ...
Developing an Active Transportation Assessment Scorecard for Rural and Suburban Communities
(2023-04-24)
In recent years, many communities have begun to focus on creating spaces for walking
and bicycling throughout their localities to reduce congestion, improve public health, and
promote economic growth. However, rural and ...
Development and Adjustment of MDOT’s Pavement Condition Ratings (PCRs)
(2022-11-30)
Pavement condition assessment is a fundamental activity of every pavement management system (PMS). It determines the overall road network condition, as well as possible maintenance and rehabilitation activities (M&R) for ...
Development and Application of Composite Beam Theory on FRP Reinforced Concrete Flexural Members
(2021-01-19)
Although there are specifications and approaches for the design of concrete flexural members reinforced with FRP, most of them were derived from empirical data. In order to obtain the rigorous theoretical definition of ...
Development and Demonstration of a Flexible Performance-based Resilience Evaluation Program (PREP) Framework to Support Transportation Planning and Decision-Making
(2023-05-04)
The past decade has seen an increase in the intensity and frequency of extreme weather events around the globe. The changes in weather and climate patterns can be linked to the increasing amount of greenhouse gases, GHGs, ...
Development and Validation of an Inertial Vehicle Barrier Calculator
(2021-11-11)
The danger of malevolent vehicle penetration attempts at the perimeter of protected facilities is an increasing threat across the globe. Passive, unanchored inertial vehicle barriers rely on their mass and friction with ...
Development of Crash Modification Factor for Low-cost Median Opening Treatments at Unsignalized Intersections of Rural Divided Highways
(2022-12-09)
An effective access management technique is such that it has the lowest level of access
control to balance traffic operation and safety. Increasing the level of control can increase the
overall delay. On the other hand, ...
Development of Criteria for Fatigue Design of Horizontally Curved Steel Bridges
(2022-12-05)
