(June, 1997)Interim Report I presents the results of an in-depth literature review focusing on PCC pavement restoration techniques. Included in the report are general notes on full-depth repairs, partial-depth repairs, diamond grinding ... -
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 ... -
Use of asphalt millings in subbase applications
(April, 199)Asphalt Concrete (AC) pavements, after a certain period of their service life, exhibit various types of deterioration and damage. To remedy these problems and to increase road safety, they are often overlaid with a new ... -
Maintenance strategies for corroded structural steel
(February, )Maintenance strategies for steel highway structures Is an old topic revisited by the Involved agencies due to recent changes and Increasing awareness in the condition of the environment and the regulations relating to it. ... -
Evaluation of rutting potential of hot mix asphalt using asphalt pavement analyzer draft (original was missing pgs 19-23, 48, 49, 68-71, 82, 126-128)
(June, 2002)Rutting of flexible pavement is a widespread problem nationally, including Oklahoma. Rutting is defined as the longitudinal depression along the wheel path due to progressive movement of materials under repeated traffic ... -
Evaluation of rutting potential of hot mix asphalt using the asphalt pavement analyzer
(October, 2)A comprehensive study involving rut potential of Hot Mix Asphalt (HMA) was conducted. Both cylindrical and beam specimens of HMA were prepared using a Superpave Gyratory Compactor (SGC) and an Asphalt Vibratory Compactor ... -
Durability of chemically stabilized aggregate bases
(Aug-03)A comprehensive laboratory study was undertaken to investigate the effect of durability, namely, freeze-thaw (F-T) and wet-dry (W-D) cycles on raw and stabilized aggregate base. Four commonly used aggregates in Oklahoma, ... -
Methodology for determining the impact of highway bypasses in Oklahoma
(January, 1)Project #2160 develops a methodology for determining the impact of highway bypasses on small town business districts in Oklahoma. The focus is predicting likely impacts of proposed bypasses on US 70. Economic impacts are ... -
Laboratory and field evaluation of soil stabilization using cement kiln dust
(April, 199)A field and laboratory study was undertaken to evaluate Cement Kiln Dust (CKD) as a soil stabilizer. The perfonnance of CKD from three different sources, Holnam of Ada, Blue Circle Cement of Tulsa, and Lone Star Industries, ... -
Use of the dynamic cone penetrometer to verify and correlate with soil subgrade and aggregate base CBR values for the purposes of design of low volume traffic asphalt concete roadways
(March, 199)The use of the Dynamic Cone Penetrometer (DCP) has increased dramatically over the past several years. The primary reason for the increased use stems from improvements to the device and the development of correlation equations ... -
Impact of loaded trucks on highway infrastructure deterioration
(January, 1)Impact of loaded trucks on our transponation infrastructure system is becoming a growing concern for many State Departments of Transportation (DOTs) in the U.S. An increasing volume of loaded trucks due to the implememation ... -
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 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 IV Suggested nuclear depth gage calibration procedures
(1968-1)An experimental procedure for calibration of nuclear depth moisture and density gages is described. Calibration of the gages was accomplished utilizing laboratory standards constructed of native Oklahoma soils. The soil ... -
Subgrade moisture variations interim report II Access Tube Installation
A method for field installation of access tubes for nuclear depth moisture and density equipment is described. After review of previous installation methods, it was concluded that a special drilling unit was required to ... -
