Subgrade moisture variations interim report V Data Summary 1966-1967
(1968-4)All data collected at the first 30 field test sites during the period June 1966-August 1967 are presented. Procedures for data collection, reduction, and display are described and discussed but no evaluation or correlation ... -
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 ... -
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 ... -
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 IX Effectiveness of existing highway designs
(1970-5)The purpose of this study was to determine which existing Oklahoma highway designs give acceptable performance and why/how they resist the effects of subgrade moisture variations. After a review of pertinent factors to be ... -
Subgrade moisture variations interim report VIII Evaluation of collected data 1966-1969
(1970-6)A prime objective of this research is to related measured moisture changes to soil, climate, and pavement behavior in Oklahoma. Previous interim reports have described operational methodology, procedures for collection and ... -
Subgrade moisture variations Final Report
(1970-8) -
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, ... -
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, ... -
The use of heat pipes to prevent ice formation on highway bridge decks
(1973)Sufficient heat can be transported from the surrounding ground to a bridge deck by heat pipes to both reduce the number of freeze-thaw cycles and to reduce the time during which the surface is below freezing. In a computer ... -
Evaluation of continuously reinforced concrete pavement
(1976-5)This report compares the performance of continuously reinforced concrete pavement with and with transverse steel. The construction of a CRCP project without transverse steel was done at the insistence of the Division FHWA ... -
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 ... -
Feasibility evaluation of the implementation of concrete polymers for bridge deck applications - progress report
(1977-1)This report summarizes the work done on the project to date. The work has been divided into three phases: polymer concrete (use of polymer aggregate with no portland cement), polymer impregnated concrete, and a literature ... -
Evaluation of bituminous mixes in pavement structures interim report V - A study of transverse cracking in Oklahoma flexible highway pavements
(1977-1)Field and laboratory studies were made to investigate the nature and extent of transverse cracks on Oklahoma flexible pavements and to determine the possible causes of this form of distress. Only the influence and contribution ... -
Related studies to cathodic protection of reinforced concrete structures no. 2 - progress report
(1977-1)This progress report surnmarizes the work done on the project from its inception to the present time. The project has been divided into four sections: conductive layer, reference electrode, long-term current, and corrosion ... -
Feasibility of the implementation of solar heat sources for bridge deck applications
(1977-1)Deicing salts have caused damage and early failure of the concrete cover and corrosion of reinforcing steel of concrete bridge decks. The use of wax to internally seal Portlant Cement concrete bridge decks and the use of ... -
Bridge deck rehabilitation part III - Cathodic protection
(1977-10)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 III of this study addressed the use of ... -
An experimental product evaluation - Portland cement concrete contraction joint sealers
(1977-12)A final report by ODOT pertaining to the evaluation of Portland Cement Contraction Joint Sealers. The method of evaluation is described. These sealers were evaluated for their performance in sawed P.C. Concrete Joints. The ... -
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 ...
