Use of an H20 meter for determination of concrete moisture content in the field
(1994-10)The ability to accurately determine concrete bridge deck moisture content could increase the probability of satisfactory performance of water repellent treatment materials through choosing favorable conditions for material ... -
Breaking and seating - final report
(1995-10)A preliminary investigation of lJS 169 in Nowata county was completed in June 1988. The 9.9 km (6.2 mi) section of two-lane roadway is located 8.0 km (5.0 mi) north of the city of Nowata. The majority of the 4.5 m ( 15.0 ... -

Establishment of underdrain maintenance procedures (FHWA-OK-95-04)
(1995-5)Project #2183 analyzed the condition of underdrains and developed a method of classifying, maintaining, and, when necessary, replacing underdrain outlets. The project encompassed every region of Oklahoma and many different ... -
Expected life of Silane water repellant treatments on bridge decks (FHWA-OK-12-08)
(2012-12)This report covers techniques used to evaluate the presence of silane coatings on bridge decks in the lab and in the field. After these techniques are established they are then used to determine the effective service life ... -
Field performance monitoring and modeling of instrumented pavement on I-35 in McClain county - phase I
(2013-6)Flexible pavements comprise about 93 percent of paved roads in the United States. Although flexible pavements are widely used for reasons such as cost, constructability and consistent performance, they are often subject ... -
Energy dissipation in eighteen-foot broken-back culverts using laboratory models (FHWA-OK-12-05)
(2012-9)This report represents Phase III of broken-back culverts with a drop of 18 feet. The first phase of this research was performed for a drop of 24 feet and the second phase of this research was carried out for a drop of 6 ... -
Subgrade moisture variations interim report III Preliminary standardization and calibration procedure for nuclear depth
(1967-5)A preliminary procedure for standardization/calibration of nuclear depth backscatter moisture and density equipment is described# After a short discussion of theoretical considerations in nuclear measurement of moisture ... -
Oklahoma Department of Transportation sprayer equipment assessment & calibration workshops (FHWA-OK-09-08)
(2009-12)Oklahoma State University (OSU) Roadside Vegetation Management (RVM) Program personnel assessed and inventoried 82 ODOT herbicide spray units. At these workshops, 259 ODOT herbicide applicators were trained in sprayer ... -
Subgrade moisture variations interim report VII Subgrade temperature measurement
(1969-6)Measured moisture conditions at several existing field research sites could not be related to precipitation, and were thought to be temperature-dependent. Accordingly, subsurface thermistor probes were installed at six ... -
Subgrade moisture variations interim report VI Evaluation of collected data 1966-1967
(1968-5)Data collected at field test sites 1-30 during the period June, 1966 - August, 1967 are evaluated, relating measured subgrade moisture changes to soil, climate, and pavement conditions. Relevant data were coded on IBM cards ... -
Investigation of behavior of an embankment - final report
(1971-9)The Citadel building of the Salvation army, located at the north-west corner of Cheyenne Avenue and Easton Street in Tulsa, Oklahoma, has undergone severe structural damage since its construction in the late 1950's, from ... -
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, ... -
Revibration of concrete for bridge decks - final report
This Final Report contains the results of a study of the potential benefits of surface revibration on bridge deck concrete subiected to a wide variety of crack inducing conditions, among which are the effects of weather ... -
Roadside erosion control - final report
Experiments along Oklahoma highways on various soil materials and in the laboratory were established to find: (a) the best methods to establish bermudagrass by vegetative means; (b) the most satisfactory means of establishing ... -
Predictability of physical changes of clay-forming materials in Oklahoma
(1972-8)In cooperation with the Oklahoma Department of Highways and the Federal Highway Administration, Department of Transportation, a research project was undertaken on October 8, 1968 by the Oklahoma University Research Institute, ... -
Adaptation of the AASHO pavement design guides to Oklahoma highways
Data are reported on physical properties of roadbed structural materials from in-place samples of most of the flexible state highways built in Oklahoma over an 11-year period. Associated traffic volumes, load history and ... -
Evaluation of bituminous mixes in pavement structures interim report IV - Development of surface deformations at statehighway 51 pavement test sites
(Jul-76)The development of rutting and other deformations in the pavement surface of two sites on a new section of State Highway 51 was monitored for a two year period. Transverse profile tracings, core samples, surface nuclear ...
