Book excerpt: A review of climate science reports relevant to extreme precipitation planning for their appropriateness and application to extreme precipitation design was completed for the Ohio Department of Transportation (ODOT) Office of Hydraulic Engineering. The report responds to questions posed by ODOT related to the climate science reports, encompassing a range of topics, including context around the greenhouse gas emissions scenarios used in the reports, uncertainty associated with precipitation projections at various return periods, and interpretation of results. Points of clarifications are provided, and potential analyses or reviews are proposed in select responses.

This book was released on 1987-02-01 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surveying the dynamic field of engineering research, Directions in Engineering Research first presents an overview of the status of engineering research today. It then examines research and needs in a variety of areas: bioengineering; construction and structural design; energy, mineralogy, and the environment; information science and computers; manufacturing; materials; and transportation. Specific areas of current research opportunity are discussed in detail, including complex system software, advanced engineered materials, manufacturing systems integration, bioreactors, construction robotics, biomedical engineering, hazardous material control, computer-aided design, and manufacturing modeling and simulation. The authors' recommendations call for funding stability for engineering research programs; modern equipment and facilities; adequate coordination between researchers; increased support for high-risk, high-return, single-investor projects; recruiting of new talent and fostering of multidisciplinary research; and enhanced industry support. Innovative ways to improve the transfer of discoveries from the laboratory to the factory are also presented.

Available in PDF, EPUB and Kindle. Book excerpt: The Ohio Department of Transportation (ODOT) wishes to develop a design method for drilled shaft foundations of noise barriers, using the software program LPILE. To accomplish this task, the research team performed the following activities: 1) Determine appropriate design loads and design criteria, 2) Review and evaluate soil strength correlations for incorporation into the design method, 3) Develop the proposed design method, and 4) Compare the proposed design method to existing ODOT design tables. Using wind loads from the AASHTO LRFD Bridge Design Specifications (AASHTO, 2020), the p-y method of analysis for laterally loaded piles was used to determine the drilled shaft length for all the different cases that are included in the current noise barrier foundation design tables in the Bridge Design Manual (ODOT, 2022a). The comparison of results to the existing design tables generally found very good agreement for granular soils. In the majority of cases the difference is only 0.5 foot. However, for the cohesive soils, there are some significant differences. For soft cohesive soils with N=0-1 the existing design table appears to be unconservative when compared to the results from the current study. In some cases, the drilled shaft lengths should be increased by up to 3 feet. While for stiffer cohesive soils the existing design table is much more conservative than the results from the current study. Also considered was the effect that varying the axial load and the addition of ice loads had on the shear, moment, and percent deflection for a noise barrier foundation located in a granular soil with N=10-19 and the maximum panel spacing (24 ft) and barrier height (20 ft). The increase in axial load slightly increases the shear and moment in the foundation. The small moment created by the off-center ice loads does not have a significant effect on the shear and moment in the noise barrier foundation. The addition of ice load does show an increase in the percent deflection of the noise barrier. The proposed design method may also be used to design a noise barrier foundation that falls outside the limits of the design tables in the ODOT Bridge Design Manual. The proposed design method has been adapted for this purpose and described in a white paper. The white paper describes the loading, design procedure, and the method of interpreting the results. It is intended for ODOT design consultants to use when the standard design tables do not apply.

Book excerpt: Though faced with continuously increasing maintenance due to aging infrastructure and limited funding, Ohio Department of Transportation is striving to maintain and improve the efficiency and safety of the state highway system. One of the major tasks is reducing highway crashes. Skid resistance is currently the road surface characteristic that has the best-established relationship with crash risk. ODOT's Highway Safety Section monitors wet/dry pavement crash rates to identify areas of concern and the pavement friction testing are performed and the skid data is collected. It is known that pavement sections have varying friction demand based on the speed, type of facility, geometrics, ingress/egress, and a host of other factors. Unfortunately, there is no straightforward methodology that we are aware of to determine friction demand in terms of friction skid numbers (SN) for different roadway conditions in the current pavement friction management (PFM) system. In order to address this problem, in this project, a comprehensive review of the current practice of managing skid resistance to address safety concerns was carried out. Then a comprehensive database was constructed from four ODOT-maintained databases. Next, a preliminary friction demand site categories were proposed and discussed with ODOT Subject Matter Experts based on literature and existing pavement management practices. Some criteria in the definition of site categories have been further adapted by analyzing Ohio crash data. Then, based on the proposed friction demand site categories, two strategies have been employed to determine the friction demand for each site category, namely 1) AASHTO method III and 2) clustering analysis. Based on the clustering analysis results, investigatory levels of SN40S and SN40R for each friction demand site category were recommended.
