USE OF MSE TECHNOLOGY TO STABILIZE HIGHWAY EMBANKMENTS AND SLOPES IN OKLAHOMA (FHWA-OK-11-04 2214)
(2011-3)
Departments of transportation across the U.S. are faced with the persistent problem of landslides and slope failures along roads and highways. Repairs and maintenance work associated with these failures cost these agencies ...
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, ...
SETTLEMENT BEHAVIOR OF COMPACTED OKLAHOMA SOILS (FHWA-OK 02(03) 2152)
(2003-2)
Numerous highway embankments experience post-construction settlement problems, such as bridge approach settlement that results in the "bump at the end of the bridge." One of the causes may be wetting-induced collapse ...
VALIDATION AND REFINEMENT OF CHEMICAL STABILIZATION PROCEDURES FOR PAVEMENT SUBGRADE SOILS IN OKLAHOMA – VOLUME I FINAL REPORT (FHWA-OK-11-02 2207)
(2011-7)
Additions of byproduct chemicals, such as fly ash or cement kiln dust, have been shown to increase the unconfined compression strength (UCS) of soils. To be considered effective, the soil must exhibit a strength increase ...
The Effects of Soil Suction on Shallow Slope Stability / Gerald A. Miller, Amy B. Cerato, Arash Hassanikhah, Maryam Varsei, Roy Doumet, Celine Bourasset, Rifat Bulut
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-12)
Research work described in this report was undertaken to improve understanding of desiccation cracking and shallow slope failures in clayey slopes subjected to seasonal variations in weather. Research involved field and ...
Calcium-Based Stabilizer Induced Heave in Oklahoma Sulfate-Bearing Soils (FHWA-OK-11-03 2210)
(2011-7)
The addition of lime stabilizers can create problems in soils containing sulfates. In most cases, lime is mixed with expansive soils rendering them non-expansive; however, when a certain amount of sulfate is present naturally ...
Prototype reinforced soil embankment for reconstruction of US 62 slope failure in Chickasha, OK
(Oklahoma City, OK : Oklahoma Department of Transportation, 2014., 2015-01)
One of the main concerns in internal stability of reinforced soil structures constructed with fine-grained or marginal quality soils is the change in shear strength of the soil-reinforcement interface when the soil gravimetric ...
VALIDATION AND REFINEMENT OF CHEMICAL STABILIZATION PROCEDURES FOR PAVEMENT SUBGRADE SOILS IN OKLAHOMA – VOLUME II (FHWA-OK-11-02(2))
(2011-10)
For projects involving a chemically stabilized layer as a part of the structural design of the pavement, it is typical to conduct a mix design to assess the additive content needed to achieve a certain unconfined compressive ...
Evaluation and Field Verification of Strength and Structural Improvement of Chemically Stabilized Subgrade Soil (FHWA-OK-07-09 2195)
(2007-7)
Often subgrade soils exhibit properties, particularly strength and/or volume change properties that limit their performance as a support element for pavements. Typical problems include shrink-swell, settlement, collapse, ...
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, ...
