Evaluation of Paver Vibrator Frequency Monitoring and Concrete Consolidation, HR-1068, 1999

Identification of ways to enhance consistency and proper entrained air content in hardened concrete pavement has long been a goal of state highway agencies and the Federal Highway Administration. The work performed in this study was done under FHWA Work Order No: DTFH71-97-PTP-IA-47 and referred to as Project HR-1068 by the Iowa DOT. The results of this study indicate that the monitoring devices do provide both the contractor and contracting authority and are a good way of controlling the consistent rate of vibration to achieve a quality concrete pavement product. The devices allow the contractor to monitor vibrator operation effectively and consistently. The equipment proved to be reliable under all weather and paver operating conditions. This type of equipment adds one more way of improving the consistency and quality of the concrete pavement.

Examination of Highway Maintenance Garages in the U.S. 30 Corridor between Ames and Cedar Rapids, 1988

A linear programming model is used to optimally assign highway segments to highway maintenance garages using existing facilities. The model is also used to determine possible operational savings or losses associated with four alternatives for expanding, closing and/or relocating some of the garages in a study area. The study area contains 16 highway maintenance garages and 139 highway segments. The study recommends alternative No. 3 (close Tama and Blairstown garages and relocate new garage at Jct. U.S. 30 and Iowa 21) at an annual operational savings of approximately $16,250. These operational savings, however, are only the guidelines for decisionmakers and are subject to the required assumptions of the model used and limitations of the study.

Needs Assessment Study of the Iowa DOT Maintenance Facility Construction Needs, 1989

The purpose of this study is to provide recommendations relative to the location and construction needs for highway maintenance facilities within the state of Iowa. These recommendations were to be developed with consideration being given to the public's expectations and priorities for highway maintenance services. As a part of the study effort, a review was made of the methods used by other states to deliver highway maintenance services. To accomplish the study, Wilbur Smith Associates undertook a series of tasks. These efforts included gathering of data and information to characterize the various maintenance programs and the delivery of maintenance and operations services by the Department. We researched the delivery of highway maintenance services in other states. Interviews with Iowa DOT maintenance personnel were accomplished. A schedule of public hearings was developed and ten hearings were held. All the information was integrated and various analyses were made. From these analyses we drew conclusions and developed recommendations.

Un ordenador por alumno: reflexiones del profesorado de Cataluña sobre los entornos 1x11

En la primera parte de este trabajo se presentan algunas reflexiones en torno a las recientes políticas educativas estatales de incorporación de las TIC en los centros educativos siguiendo el modelo de un ordenador por alumno. En una segunda parte, se aborda la concreción en Cataluña del proyecto Escuela 2.0 y la valoración que realiza el profesorado de esta comunidad autónoma de los entornos 1x1.

Statistical Analysis of Highway Needs Condition Data: Manual vs. Automated, TR-494

This project examines similarities and differences between the automated condition data collected on and off county paved roads and the manual condition data collected by Iowa Department of Transportation (DOT) staff in 2000 and 2001. Also, the researchers will provide staff support to the advisory committee in exploring other options to the highway need process. The results show that the automated condition data can be used in a converted highway needs process with no major differences between the two methods. Even though the foundation rating difference was significant, the foundation rating weighting factor in HWYNEEDS is minimal and should not have a major impact. In terms of RUTF formula based distribution, the results clearly show the superiority of the condition-based analysis compared to the non-condition based. That correlation can be further enhanced by adding more distress variables to the analysis.
