(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, ... -
Dynamic cone penetrometer user's guide
(March, 199)The Dynamic Cone Penetrometer (DCP) is a rapid and inexpensive device for characterizing unbound paving materials and subgrade soils. The DCP may be used to estimate the strength of these materials through the use of ... -
Effect of field variables and test procedures on silane weatherproofing performance (FHWA-OK-93-02) 2178
(1993-6)The performance of a generic silane penetrating water repellent material was evaluated using alternate test procedures . Field variables introduced into the laboratory tests included: 1) concrete mix design, 2) concret~ ... -
EFFECT OF Y-CRACKING ON CRCP PERFORMANCE (FHWA-OK-12-07 2230)
(2012-10)This report covers the investigation of the impact of Y-cracking on concrete pavements in Oklahoma. This study used field and analytical investigations to determine the impact of Ycracking on the long term performance of ... -
Effectiveness of riverbank protection and river control in Oklahoma (FHWA-OK-89-08)
(1989-8)Bank stabilization and protection from flood ravages have been a continuing problem in Oklahoma as well as in the surrounding states for a very long time. Bridges and hydraulic structures are situated at river sites where ... -
EFFICACY OF ROAD BOND AND CONDOR AS SOIL STABILIZERS (FHWA-OK-13-06 2242)
(2013-8)The Oklahoma Department of Transportation (ODOT) uses lime-based stabilizers including quick lime, hydrated lime, Class C fly ash (CFA) and cement kiln dust (CKD) to increase bearing capacity of fine-grained subgrade soils ... -
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 ... -
ENERGY DISSIPATION IN THIRTY-FOOT BROKEN-BACK CULVERTS USING LABORATORY MODELS
(2014-09)This research investigates the reduction in scour downstream of a broken-back culvert by forming a hydraulic jump inside the culvert. A broken-back culvert is used in areas of high relief and steep topography as it has one ... -
ENERGY DISSIPATION IN TWELVE-FOOT BROKEN-BACK CULVERTS USING LABORATORY MODELS (FHWA-OK-13-07)
(2013-9)This report represents Phase IV of broken-back culverts with a drop of 12 feet. The first phase of this research was performed with a drop of 24 feet, the second phase of this research was carried with for a drop of 6 feet, ... -
