(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 ... -
DEVELOPMENT OF RATING TOOL FOR PRESTRESSED CONCRETE BRIDGES VULNERABLE TO SHEAR (FHWA-OK-20-01 Revision 1 2280)
(2020-01)A study was conducted examining the factors affecting shear capacity and load rating, two potential methods for assessing condition of in-service prestressed concrete bridge girders, and a simple procedure for assessing ... -
Discarded tires in highway construction (FHWA-OK-82-4) 2411
(1982-11)This report discusses a single bituminous surface treatment using an asphalt-rubber binder and pre-coated aggregate over a bleeding and cracked asphalt concrete highway. Tests and evaluations include: a pavement condition ... -
DISTRESS MODELING FOR DARWIN-ME (FHWA-OK-13-10 2235)
(2013-12)Distress prediction models, or transfer functions, are key components of the Pavement M-E Design and relevant analysis. The accuracy of such models depends on a successful process of calibration and subsequent validation ... -
DRYING SHRINKAGE PROBLEMS IN HIGH PI SUBGRADE SOILS
(2014-1)The main objective of this study was to investigate the longitudinal cracking in pavements due to drying shrinkage of high PI subgrade soils. The study involved laboartory soil testing and modeling. The shrinkage cracks ... -
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, ... -
