STAINLESS STEEL REINFORCEMENT AS A REPLACEMENT FOR EPOXY COATED STEEL IN BRIDGE DECKS (FHWA-OK-13-08 2231)
(2013-8)
The corrosion resistance of 2304 stainless steel reinforcement and stainless steel clad reinforcement was compared to conventional and epoxy-coated reinforcement (ECR). 2304 stainless steel was tested in both the as-received ...
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 ...
NEW ASPHALT MIX DESIGN SYSTEM FOR OKLAHOMA DEPARTMENT OF TRANSPORTATION (FHWA-OK-13-03 2238)
(2013-3)
Oklahoma Department of Transportation (ODOT) has been using the Superpave mix design software for several years. The original Superpave mix design software was built around Fox Database and did not meet ODOT requirements. ...
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 ...
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 ...
Analysis of Aggregates and Binders Used for the ODOT Chip Seal Program (FHWA-OK-10-03 2221)
(2010-11)
This project compared the results of laboratory characterization of chip seal aggregate samples for Oklahoma DOT Divisions 1,2,3,5 and 6 with performance data from the Pavement Management System (PMS) database. Binder ...
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 ...
OKLAHOMA ROADSIDE VEGETATION MANAGEMENT GUIDELINES - 4TH EDITION (FHWA-OK-09-02 2156)
(2010-1)
A fourth edition of the Oklahoma Roadside Vegetation Management Guidelines was developed. The guidelines serve as a training and reference manual for Oklahoma Department of Transportation (ODOT) employees that are responsible ...
INVESTIGATION OF OPTIMIZE GRADED CONCRETE FOR OKLAHOMA - PHASE 1 (FHWA-OK-13-12 2160)
(2013-10)
Optimized Graded Concrete has been a subject widely discussed through the history of concrete. Since aggregates make up over 70% of the volume in a mixture, gradation is critical to the strength, workability, and durability ...
