Sealing cracks in flexible pavements interim report I - flexible pavement crack sealing practices and research approach
(1977-2)In response to a request from the Research Division, a research proposal entitled "Sealing Cracks in Flexible Pavements" was presented to the Oklahoma Department of Transportation in February, 1976. This proposal was for ... -
The development of a portable steel reinforcing bar detection device for concrete bridge decks - second quarterly report
(1977-4)During the last quarter a variety of steel reinforcing bar (rebar) detection schemes were studied so that an optimum sensing device could be selected. It was found that magnetic techniques were superior to infrared, ... -
Evaluation of bituminous mixes in pavement structures - final report
(1977-6)A summary of the research methodology, results, conclusions and recommendations of a five-year study of bituminous mixtures used in Oklahoma flexible highway pavements is presented in this terminal report. The research ... -
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 ... -
Bridge deck rehabilitation part I - methods and materials
(1977-8)The bridge deck deterioration processes of freeze-thaw scale, popout, and corrosion induced spalling are defined and the popular theories accounting for their mechanism are explained. Included is a basic discussion of ... -
Experimental investigation of solar heating of bridge decks
(1978-10)The addition of monomers or the inclusion of wax within highway bridge decks are two methods being used to prevent salt penetration during winter deicing. Both of these methods require the addition of heat until the upper ... -
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 ... -
Bridge deck rehabilitation part II - Oklahoma's experience with bridge deck protective systems
(1978-6)The objectives of this project were to study the factors involved in bridge deck deterioration and to formulate and evaluate. techniques to prevent or halt such deterioration. Part II of this project was concerned with the ... -
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 ... -
Sealing cracks in flexible pavements interim report II - crack dynamics field study
(1979-5)The first interim report on Project 77-02-3. "Sealing Cracks in Flexible Pavements", was submitted to the Oklahoma Department of Transportation (ODOT) in February, 1977 (1). This report contained a review of literature on ... -
Sealing cracks in flexible pavements interim report III - laboratory tests of asphalt sealants
(1979-5)A survey of literature pertaining to materials and methods of sealing highway pavement cracks indicated a scarcity of information and a lack of standard testing procedures for asphalt pavement crack sealants. Therefore, ... -
Bearing capacities and characterization of compressible clayey and silty foundation soils in Oklahoma (FHWA-OK-81-3) 239
(1980-12)This study developes a characterization of alluvial soils in two river systems from the surface down to bedrock. Study sites were located in alluvial deposits where fill settlement is a problem. Continuous undisturbed soil ... -
Polymer impregnated concrete and polymer concrete overlays
(1980-4)The feasibility of impregnating bridge decks with methylmethacrylate for protection against freeze-thaw deteriorization and corrosion of the reinforcing steel is reported. Parameters such as monomer system, monomer loading, ... -
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 ... -
Final report on corrosion of reinforcing steel in concrete containing fly ash (79-11)
(1981-1)In July 1979, the Oklahoma Department of Transportation funded a research program at Oklahoma State University concerned with the performance of concrete containing fly ash (State Study No. 79-11-3), Initially, attention ... -
Epoxy coated reinforcing steel in bridge decks (FHWA-OK-81-3) 717
(1981-11)The objective of this project is to study the application ot fusionbonded epoxy coatings ot rebars in bridge decks. A thin fiim of epoxy resin is fusion bonded to the reinforcing steel as a prevention against corrosion. A ... -
Sealing cracks in flexible pavements final report - field and laboratory evaluation of crack sealants
(1981-12)This study is the terminal portion of a three phase research project entitled "Sealing Cracks in Flexible Pavements." The project was initiated in response to a request from the Research Division of the Oklahoma Department ... -
Implementation of research findings - drilled shaft investigation (FHWA-OK-81-06) 602
(1981-12)The purpose of this report is to establish soil properties of Oklahoma flood plain (alluvial) soils for drilled shaft design. Also, to establish a correlation between shear strength (Su) obtained from unconfined compression ... -
