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 ...
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, ...
Interpretation of In Situ Tests as Affected by Soil Suction / Gerald A. Miller, Rodney W. Collins, Kanthasamy K. Muraleetharan, Amy B. Cerato, Roy Doumet.
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-12)
In situ testing of soil with invasive methods such as the Cone Penetration Test (CPT) are increasingly used in geotechnical engineering practice. However, there has been very little work to develop methods for interpreting ...
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 ...
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 ...
