This study analyzes the economic impacts of load limits and the benefits of establishing a statewide program to coordinate the administration of load limits. The study reported truck size and weight regulations as well as state permitting policies and costs for various types of permits in North Dakota....
The focus of this study is on the potential role of transportation infrastructure in expanding sales of goods outside the state. Much of the freight exported from North Dakota moves by rail. Therefore, both highway and railroad system are analyzed. To the extent possible, the benefits and costs associated...
This research considers the influence of different construction materials on the dynamic impact factor of bridges. The general concept of the dynamic impact factor and typical evaluation methods are reviewed.
Lateral loading on pile groups often controls the design of these foundation systems, but their behavior when subjected to lateral loading is extremely difficult to predict. To compensate for this, factors of safety are increased, thus increasing the overall cost of a project. The purpose of this research...
The primary objective of this study was to investigate the effects of freeze-thaw conditioning and overloading on the resilient modulus (Mr) of subgrade soils susceptible to frost penetration. The Mr values of conditioned samples were compared to unconditioned samples. All Mr values were determined in...
