This report is an interim report for the first phase of an ongoing project entitled "Moderate Weight Bridge Guardrail for Rural Sites." The objective is to examine the potential of a new bridge guardrail concept as a means of increasing the safety of travel over rural bridges. This project is conducted...
A research study was conducted to investigate the potential application of Intelligent Vehicle/Highway Systems (IVHS) technologies for reducing accidents on rural roads. After studying existing technologies, their present application to transportation, and approaches to identifying predominant accident...
This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus value. The objectives of this study were to first, investigate the importance of several fundamental...
This project included two laboratory studies and analytical work dealing with T-beams comprised of a concrete flange connected to a wood beam plus plywood sheathing. Based on the experimental results of tests of 72 slip specimens and 4 full-scale layered T-beams, the mechanical behavior of different...
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...
