Slope stability of certain selected colluvial soils
(1977-6)The objective of this study is to characterize natural clayey colluvial soils that occur in eastern Oklahoma. Three study sites were selected in areas of known landslides. Piezometers and permeability bore holes were placed ... -
Slope stability of certain selected colluvial soils - implementation package
(1978-11)The purpose of this report is to inform State Design, Construction, and Maintenance Engineers of accepted procedures for the investigation and design of potential landslide prone areas. State Materials and Geotechnical ... -
Slurry seal crack treatment
(1976-5)In the spring of 1975 the resurfacing project 1-35-3(88)126 was started. The experimental part of the project consisted of the use of an asphalt slurry to fill and seal cracks and spalls in the existing pavement, followed ... -
Solar energy heating of asphalt to 200 F in storage tanks - final report
(1980-9)A high-temperature (185 - 225°F) asphalt storage system has been designed and constructed at Perry, Oklahoma. This report documents the design process, construction procedures, and evaluates data gathered to date. The ... -
Solar heated maintenance building at Chickasha (80-07-1)
(1983-2)In December, 1980, a solar heating system was installed at the Oklahoma Department of Transportation Maintenance Building in Chickasha, Oklahoma. The system is based on an air type flat plate solar collector with an ... -
Splices in tensile reinforcing bars
(1965-8)The purpose of this project was to provide information on the relative merits of the various methods of connecting tensile reinforci ng bars in reinforced concrete construction. This project consisted of two parts. In Part ... -
Stability and Permeability of Proposed Aggregate Bases in Oklahoma (FHWA-OK-09-05 2196)
(2010-5)Aggregate base is an important component of a pavement structure. It supports the asphalt concrete (AC) layer and reduces the wheel load-induced stresses on the underlying layers. It also functions as a drainage layer. ... -
Stabilization of Oklahoma shales - final report
(1977-12)In cooporation with the Oklahoma Department of Transportation and the Federal Highway Administration, U.S. Department of Transportation, a research project was undertaken on June 1, 1973, by the University of Oklahoma to ... -
Stabilization of Oklahoma shales field implementation phases
(1984-9)The improvement of U.S. 77 north of Ponca City, Oklahoma, into a four-lane divided highway involves the use of expansive clay as a subgrade material. To stabilize it, Portland cement, fly ash, lime and their conjunctive ... -
STAINLESS STEEL REINFORCEMENT AS A REPLACEMENT FOR EPOXY COATED STEEL IN BRIDGE DECKS (FHWA-OK-13-08 2231)
(2013-8)The corrosion resistance of 2304 stainless steel reinforcement and stainless steel clad reinforcement was compared to conventional and epoxy-coated reinforcement (ECR). 2304 stainless steel was tested in both the as-received ... -
Statistical models for identification of problematic bridge sites and estimation of approach settlements (FHWA-OK-94-02) 2188
(1995-5)Bridge approach settlement is caused by the differential movements of the bridge abutment and the approach pavement. The resulting unsafe riding surface not only requires frequent and costly maintenance but also leads to ... -
Statistical quality control of Portland cement concrete pavements
(1968-6)The scope of this investigation was to study statistically the process of preparing concrete for Portland cement concrete pavements and to compare the data with the specifications in use. It encompassed the measurement of ... -
Strain gage data collection for determining effective stress and cycles for inspection intervals on bridges
(September,)The data logger was presented to Research, Development and Technology Transfer ( RD&TT) of the Oklahoma Department of Transportation (ODOT) in hopes of determining why readings could not be ascertained from the unit or ... -
Strength characteristics of the stabilized boggy shale (79-09-2)
(1979-11)In cooperation with the Oklahoma Department of Transportation and the Federal Highway Administration, U.S. Department of Transportation, a research project entitled "Field Application of the Stabilization of Oklahoma ... -
Strengthened earth wall (FHWA-OK-97-09) 2731
(1997-11)The Oklahoma Department of Transportation (ODOT) recently completed a project that included a Strengthened Earth Wall. The Mechanically Stabilized Earth (MSE) wall was constructed by Muskogee Bridge Company as a part of ... -
Study of the wearability and polish resistance of Oklahoma's coarse aggregates - final report
(1972-12)This report describes a laboratory attempt to evaluate the wearability and polishing characteristics of "nonpolishing" stones when blended with a sound, polish susceptible stone. The effects of crystallinity, grain size, ... -
