Research Reports
View AllMany rural governments do not have an effective safety improvement program for their roads, yet crash rates are significantly higher on rural roads than on urban, state, and federal roads. Smaller agencies seldom have the financial resources or expertise to provide comprehensive roadway safety improvement... This report examines the feasibility of using the thermal stress restrained specimen test to evaluate low temperature cracking in asphalt pavement mixes. Data were collected from laboratory and field evaluations. Various mixing, aging, and compaction methods were used to prepare test samples with materials... Traffic control alternatives associated with reconstruction projects on a rural interstate have been investigated in this research. Slab replacement projects, milling/resurfacing projects, and traffic controls in the vicinity of interstate ramps were analyzed. The recommendations obtained from a national...

Traffic control alternatives associated with reconstruction projects on a rural interstate have been investigated in this research. Slab replacement projects, milling/resurfacing projects, and traffic controls in the vicinity of interstate ramps were analyzed. The... This report describes the development of a Standard Modular Data Storage System. Features such as inventory data, pavement management data, and other maintenance data can be organized as modules in a common data repository. This repository can be imported into an enterprise database such as Informix.... In this research, a practical approach to identifying street safety needs for local governments has been developed. These governments are responsible for high street mileage carrying relatively low traffic volumes. Improving safety on these streets is given only limited focus in most small cities. Due... This project evaluated the opinions of commercial vehicle drivers and safety inspectors regarding the roadside inspection process and motor carrier safety. Surveys were developed in cooperation with the Office of Motor Carriers and used to question a representative sample from each of the groups nationwide.... This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. This document is a compendium of motor carrier projects in progress (as of August 1998) and completed by the Upper Great Plains Transportation Institute, North Dakota State University. Each entry includes project title, investigator, and a brief description. In 1991 federal transportation legislation, Congress mandated that state DOT's develop and implement comprehensive bridge management systems (BMS). Related to this, a rigorous BMS software package, PONTIS, was developed via federal contracting to industry. |
