The main objective of this research was to quantify the differences and similarities among Quality Control/ Quality Assurance (QC/QA) programs for three state highway agencies. By measuring these differences, conclusions were drawn as to which state was achieving the best results with their QC/QA program....

In this study, the researchers evaluated the effectiveness of quality control/quality assurance (QC/QA) specifications in decreasing hot mix asphalt (HMA) variability. A questionnaire was written to gather general information about the QC/QA specification programs that are being used in the United States...

A survey of the education and training needs was conducted and more than 2,000 questionnaire booklets were sent to highway contractors nationwide. Two hundred and eighteen responded. The objective of the survey was to determine the training and education needs of the construction industry and identify...

The present research suggests a new approach to the use of composite materials technology for repair of timber structural members. Due to the small aspect ratio of the typical railroad bridge span timbers, stiffness degradation can be related to decrease in the beam's shear performance. To rejuvenate...

Evaluation of Pavement Shoulders (May 1999, MPC-99-101)

In this study the researchers examined the effect of pavement shoulders on the safety and structural strength of highways in Wyoming. The costs of adding shoulders to various types of highways also was examined. The study consisted of selecting representative highway sections, collecting accident data...

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...

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...

Appendix for MPC-98-98A Volume 1. 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 study addresses the issue of retrofitting reinforced concrete column/cap joints with advanced carbon-fiber composites using full-scale laboratory specimens.

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...
